The power rule for derivatives is  -26/5.

The derivative is a fundamental concept that measures how much a function changes as its input changes. It is a mathematical tool used to find the instantaneous rate of change of a function at a specific point. The derivative of a function f(x) at a point x=a, denoted by f'(a), is the slope of the tangent line to the graph of f(x) at the point (a, f(a)).

a. f(x) = 2x³

Using the power rule for derivatives, we have:

f'(x) = 6x²

So, f'(2) = 6(2)² = 24.

b. g(x) = 13x^(1/2)

Using the power rule for derivatives, we have:

g'(x) = (1/2) * 13x^(-1/2) = (13/2√x)

So, g'(3) = (13/2√3).

c. h(x) = hx

Using the power rule for derivatives, we have:

h'(x) = h

So, h'(4) = h.

d. j(x) = 130x^(-1)

Using the power rule for derivatives, we have:

j'(x) = -130x^(-2)

So, j'(5) = -130(5)^(-2) = -130/25 = -26/5.

It takes 30 minutes for 5 old printers to produce a batch of comic books.
It takes 18 minutes for 4 new printers to produce an identical batch of
comic books.
a) Which of the following would produce a batch of comic books in less
time:
6 old printers or 2 new printers?
b) How much less time would this take?

Answers

It should be noted that with the equations 6 old printers would produce a batch of comic books in less time.

Using 2 new printers is 27 minutes faster than using 6 old printers.

How to solve the information

6 old printers would produce 6*(1/150) = 2/75 of a batch per minute.

2 new printers would produce 2*(1/72) = 1/36 of a batch per minute.

(5/6) * t = 30

(4/2) * t' = 18

Solving for t and t', we get:

t = 36 minutes

t' = 9 minutes

Therefore, using 6 old printers would take 36 minutes to produce a batch of comic books, while using 2 new printers would take only 9 minutes. Using 2 new printers is 27 minutes faster than using 6 old printers.

Fran is training for her first marathon, and she wants to know if there is a significant difference between the mean number of miles run each week by group runners and individual runners who are training for marathons. She interviews 32 randomly selected people who train in groups, and finds that they run a mean of 49. 0 miles per week. Assume that the population standard deviation from group runners is known to be 4. 2 miles per week

Answers

Our calculated t-value (-2.54) is beyond this critical value, we can reject the null hypothesis and conclude that there is a significant difference between the mean number of miles run per week by group runners and individual runners.

To test if there is a significant difference between the mean number of miles run each week by group runners and individual runners who are training for marathons, we can use a two-sample t-test.

Let's assume that the population standard deviation for the individual runners is also 4.2 miles per week.

We can set up the hypotheses as follows:

Null hypothesis: The mean number of miles run per week by group runners and individual runners is the same.

Alternative hypothesis: The mean number of miles run per week by group runners and individual runners is different.

Mathematically, we can write:

H0: μ1 = μ2

Ha: μ1 ≠ μ2

where μ1 is the population mean for group runners and μ2 is the population mean for individual runners.

We are given the sample mean for the group runners, which is 49.0 miles per week. We do not know the sample mean for the individual runners. Let's assume that we collect a random sample of 32 individual runners and find that their sample mean is 52.0 miles per week.

We can calculate the test statistic as follows:

t = (X1 - X2) / sqrt((s1^2/n1) + (s2^2/n2))

where X1 and X2 are the sample means for group runners and individual runners, s1 and s2 are the population standard deviations for group runners and individual runners, and n1 and n2 are the sample sizes for group runners and individual runners.

Plugging in the values, we get:

t = (49.0 - 52.0) / sqrt((4.2^2/32) + (4.2^2/32))

t = -3.0 / 1.182

t = -2.54

Using a t-distribution table with 62 degrees of freedom (32 + 32 - 2), we can find that the critical value for a two-tailed test with a significance level of 0.05 is approximately ±2.0. Since our calculated t-value (-2.54) is beyond this critical value, we can reject the null hypothesis and conclude that there is a significant difference between the mean number of miles run per week by group runners and individual runners.

The loudest animal on earth is the blue whale. blue whales can emit sound with an intensity of 106.8 watts/meter2. the equation relates the sound level, , in decibels (db), of a noise with an intensity of i to the smallest sound intensity that can be heard by the human ear, (approximately watts/meter2).based on this information, which value is closest to the sound level, in decibels, of the vocalizations of a blue whale?

Answers

The sound level of the vocalizations of a blue whale is approximately 140.28 decibels.

How to find sound level?

The question asks us to find the sound level in decibels (db) of the vocalizations of a blue whale, given its sound intensity of 106.8 watts/meter2.

The formula for sound level in decibels is:

L = 10log(i/I0)

Where L is the sound level in decibels, i is the sound intensity in watts/meter2, and I0 is the smallest sound intensity that can be heard by the human ear (approximately 1x10⁻¹² watts/meter2).

Plugging in the given values, we get:

L = 10log(106.8/1x10⁻¹² )

Simplifying this expression, we get:

L = 10log(1.068x10¹⁴)

L = 10(14.028)

L = 140.28

Therefore, the sound level of the vocalizations of a blue whale is approximately 140.28 decibels.

The swamp has a perimeter 124 feet the length L of the swamp is 10 less than 5 times it width W

Answers

The width of the swamp is 12 feet, and the length is 50 feet.

How to solve for the length and the width of the swamp

length is 10 less than 5 times its width. We can write that as:

Equation for length:

L = 5W - 10

We also know that the perimeter of the swamp is 124 feet. The formula for the perimeter of a rectangle is:

Perimeter = 2(Length + Width)

So, we have:

124 = 2(L + W)

Now, we can substitute the expression for L from the first equation into the second equation:

124 = 2((5W - 10) + W)

Now, we can solve for W:

Step 2: solving for width

124 = 2(6W - 10)

62 = 6W - 10

72 = 6W

W = 12

Now that we have the width (W = 12 feet), we can find the length by plugging the width back into the equation for L:

Step 1: solving for length

L = 5W - 10

L = 5(12) - 10

L = 60 - 10

L = 50

So, the width of the swamp is 12 feet, and the length is 50 feet.

Cooper is studying two fractions that are both less than 1 the first fraction has a denominator of 4 and rounds to 1. the second fraction has a denominator of 6 and the same numerator as the first fraction is the second fraction closest to 1 or 17 explain

Answers

The first fraction is closer to 1, while the second fraction is closer to 17.

Let's first determine the value of the first fraction with a denominator of 4, which rounds to 1.

Since the fraction is less than 1 and rounds to 1, its numerator must be 3. Therefore, the first fraction is:

3/4 = 0.75

Now let's consider the second fraction, which has a denominator of 6 and the same numerator as the first fraction. So its value is:

3/6 = 1/2 = 0.5

To determine which fraction is closer to 1 or 17, we need to calculate the absolute difference between the value of each fraction and 1 or 17, and then compare those differences.

For the first fraction, the absolute difference between 0.75 and 1 is:

|1 - 0.75| = 0.25

The absolute difference between 0.75 and 17 is:

|17 - 0.75| = 16.25

For the second fraction, the absolute difference between 0.5 and 1 is:

|1 - 0.5| = 0.5

The absolute difference between 0.5 and 17 is:

|17 - 0.5| = 16.5

Therefore, the first fraction is closer to 1, while the second fraction is closer to 17.

Answers

Bristol is the cheapest city and Paul can drop from his plans to stay under budget.

To determine which city Paul can drop and still stay under budget, we need to find the total cost of visiting all four cities and compare it to Paul's budget of £300.

We do not have information about the cost of sightseeing in each city, so we will assume that the cost is the same for each city. In that case, the cost of visiting all four cities is:

Cost of visiting all cities = Cost of visiting one city x 4

Let's call the cost of visiting one city "x". Then:

Cost of visiting all cities = x * 4

To stay under budget, the cost of visiting all cities must be less than or equal to £300. So we can write the following inequality:

Simplifying this inequality, we get:

x ≤ £75

https://brainly.com/question/14124581

The answer is (c) Bristol, as it has the highest cost among the remaining cities and dropping it would leave Paul with 224 pounds, which is still within his budget.

What is budget?

A budget is whenever one plans on how to spend an estimated income. All the income should be considered as well as all the expenses. In other words, it is an expending plan.

The total cost of visiting all cities is:

76 + 66 + 91 + 60 + 72 = 365

To stay under budget, Paul must drop at least one city. To determine the cheapest city to drop, we can calculate the cost of the trip to each city if visited individually and compare it to the remaining budget:

- Bristol: 76 pounds

 Remaining budget: 300 - 76 = 224 pounds

- Leicester: 66 pounds

 Remaining budget: 300 - 66 = 234 pounds

- Glasgow: 91 pounds

 Remaining budget: 300 - 91 = 209 pounds

- Leeds: 60 pounds

 Remaining budget: 300 - 60 = 240 pounds

- Belfast: 72 pounds

 Remaining budget: 300 - 72 = 228 pounds

The city that Paul can drop while staying under budget is the one with the lowest cost.

Therefore, the answer is (c) Bristol, as it has the highest cost among the remaining cities and dropping it would leave Paul with 224 pounds, which is still within his budget.

Stevie has a yard cleanup business. He initially spent $175 for equipment (mower, rakes, bags, etc. ). He charges $12 hours for cleanup. How many hours of work will he need to do in order to make at least $1200? (Let hh = number of hours worked)

Answers

Stevie will need to work at least 150 hours to make at least $1200 after accounting for the initial cost of equipment.

How to find hours of work?

to find the business hours of work, Let's start by defining the variables given in the problem:

The initial cost of equipment is $175.

Stevie charges $12 per hour for cleanup.

Stevie wants to make at least $1200.

The number of hours worked is represented by h.

Now, we can set up an equation to solve for h:

Total earnings - Total cost = Desired profit

We can express the total earnings as the product of the hourly rate and the number of hours worked:

Total earnings = $12h

The total cost includes the initial cost of equipment plus any additional costs incurred during cleanup:

Total cost = $175 + additional costs

Since we don't know the value of the additional costs, we'll leave it as a variable.

Substituting these expressions into the equation, we get:

$12h - ($175 + additional costs) = $1200

Simplifying the equation, we get:

$12h - $175 - additional costs = $1200

$12h - $1375 = additional costs + $1200

$12h - $1375 = additional costs

Now we have an equation that relates the number of hours worked to the additional costs incurred during cleanup. We want to find the minimum value of h that satisfies this equation, since Stevie wants to make at least $1200.

To do this, we need to estimate the additional costs incurred during cleanup. Let's assume that Stevie spends an average of $4 per hour on additional costs (e.g., gasoline, trash bags, etc.). Then, the equation becomes:

$12h - $1375 = $4h + $175

Simplifying further, we get:

$8h = $1200

h = 150

Therefore, Stevie will need to work at least 150 hours to make at least $1200 after accounting for the initial cost of equipment and the estimated additional costs incurred during cleanup.

T = 2π/ω.

What is the explanation for the above response?


1a.
let's assume that the motion of the horse can be modeled by a simple harmonic motion. The equation for simple harmonic motion is:

y = A sin(ωt + φ)

where:

y is the displacement from the equilibrium position

A is the amplitude (maximum displacement)

ω is the angular frequency (2π times the frequency)

t is time

φ is the phase angle

Assuming that the horse's motion is in a vertical direction and that the highest point of its motion corresponds to y = 0, we can write the equation as:

y = A sin(ωt)

where A is the amplitude of the motion and ω is the angular frequency.

We can plot this function as a sine wave on a graph, where the horizontal axis represents time and the vertical axis represents displacement. The period of the motion is the time it takes for the horse to complete one full cycle of motion, and it is given by:

T = 2π/ω

To determine when Ivan will get his next opportunity to take a perfect shot, we need to know the period of the horse's motion. Without additional information, it's difficult to estimate the period accurately.


The graph of the carousel equation θ = A cos(ωt) can be labeled as follows:

The x-axis represents time, t, in seconds.The y-axis represents the angular displacement, θ, in degrees, from the midline.The midline is the horizontal axis at θ = 0 degrees.The amplitude, A, is the maximum angular displacement from the midline, which is the distance between the crest (maximum point) or trough (minimum point) of the wave and the midline.The period, T, is the time it takes for one complete cycle of the motion, which is the distance between two consecutive crests or two consecutive troughs of the wave.

r = annual interest rate = 5% or 0.05 (as a decimal)

n = number of times interest is compounded per year = 1 (since it is compounded annually)

t = time period = 5 years

Plugging in the given values, we get:

A = 47000(1 + 0.05/1)^(1*5)

A = 47000(1.05)^5

A ≈ $60,625.06

So, the amount in the account after 5 years, compounded annually, will be approximately $60,625.06.

(b) For compounding semiannually:

The only difference from the above calculation is the value of 'n', which is the number of times interest is compounded per year. In this case, 'n' will be 2, as interest is compounded semiannually (twice a year).

Plugging in the given values, we get:

A = 47000(1 + 0.05/2)^(2*5)

A = 47000(1.025)^10

A ≈ $61,588.88

So, the amount in the account after 5 years, compounded semiannually, will be approximately $61,588.88.

what is the range of the exponential function

Answers

Answer:

y > -1

Step-by-step explanation:

The range is about the y, not the x, so we can eliminate options B & D.

We see the y touch -1 and then go up to ∞, so the answer is y > -1

5. Daniel arrives at his campsite out of breath from his swim and jog. His sister tells him that he should have swam to the boat ramp that is only 200 feet from the campsite and then jogged. She claims that he would have arrived quicker this way. Is Daniel's sister correct? Support your answer mathematically

Answers

Since 2 is greater than 1, it would have been faster for Daniel to swim directly to the campsite. Therefore, Daniel's sister is incorrect.

We can solve this problem using the formula for distance, rate, and time, which is:

distance = rate x time

Let's assume that Daniel swims at a rate of s feet per second and jogs at a rate of j feet per second. If he swims directly to the campsite, the distance he needs to cover is the distance d between the campsite and the boat ramp, which is 200 feet. If he swims to the boat ramp and then jogs to the campsite, he will need to cover the distance d twice, once while swimming and once while jogging. The total distance he will cover is 2d = 400 feet.

If Daniel swims directly to the campsite, the time it will take him to cover the distance is:

time1 = d/s

If he swims to the boat ramp and then jogs to the campsite, the time it will take him to cover the distance is:

time2 = d/s + d/j

To compare the two times, we can take their ratio:

time2/time1 = (d/s + d/j)/(d/s) = 1 + j/s

If this ratio is less than 1, then Daniel's sister is correct, and he would have arrived quicker by swimming to the boat ramp and then jogging. If the ratio is greater than 1, then it would have been faster for him to swim directly to the campsite.

Substituting d = 200, we get:

time2/time1 = 1 + j/s = 1 + (j/s)*(200/200) = 1 + (200j)/(ds)

Since Daniel arrives at the campsite out of breath from his swim and jog, we can assume that his rates of swimming and jogging are roughly equal. Let's assume s = j = r, where r is the common rate of swimming and jogging. Substituting this into the ratio, we get:

time2/time1 = 1 + (200r)/(dr) = 1 + 200/d

To determine if Daniel's sister is correct, we need to compare this ratio to 1. If time2/time1 is less than 1, then Daniel's sister is correct. If it is greater than 1, then it would have been faster for Daniel to swim directly to the campsite.

Substituting d = 200, we get:

time2/time1 = 1 + 200/200 = 2

Since 2 is greater than 1, it would have been faster for Daniel to swim directly to the campsite. Therefore, Daniel's sister is incorrect.

The probability that a randomly selected house with 2 bathrooms has 3 is: 0.8.

So, the fourth option is correct.

We have given that,

The two-way table shows the number of houses on the market in the Castillos’ price range.

A 6-column table has 4 rows.

The first column has entries 1 bathroom, 2 bathrooms and 3 bathrooms, in total.

The second column is labeled 1 bedroom with entries 67, 0, 0, 67.

The third column is labeled 2 bedrooms with entries 21, 6, 18, 45.

We are only considering the houses that have 2 bathrooms.

There are a total of 30 of these houses.

Out of these 30, 24 have 3 bedrooms.  

What is the formula for probability?

The probability of an event can only be between 0 and 1 and can also be written as a percentage.

This makes the probability 24/30, which is 0.8.

Therefore, the probability that a randomly selected house with 2 bathrooms has 3 is: 0.8.

So, the fourth option is correct.

What is the vertex, Line of symmetry, and how many x intercepts are there?

Answers

The vertex is the highest or lowest point on the parabola, the line of symmetry is a vertical line passing through the vertex and dividing the parabola into two equal halves, and the number of x-intercepts depends on the discriminant of the quadratic equation.

The vertex is a point on a parabola where the curve changes direction. It is the highest or lowest point on the curve, depending on whether it opens up or down. The vertex is represented as (h, k), where h is the x-coordinate and k is the y-coordinate.

The line of symmetry is a vertical line that divides the parabola into two equal halves. It passes through the vertex and is equidistant from the two arms of the parabola. The equation of the line of symmetry is x = h.

The number of x-intercepts is determined by the equation of the parabola. If the discriminant of the quadratic equation is positive, then the parabola intersects the x-axis at two distinct points, and there are two x-intercepts. If the discriminant is zero, then the parabola touches the x-axis at one point, and there is one x-intercept. If the discriminant is negative, then the parabola does not intersect the x-axis, and there are no x-intercepts.

Answers

Bob's minimum monthly credit card payment needs to be B) $129.00 to reach his dti goal of 36%.

Bob's total monthly debt payments are $1,947.00 ($1,250.00 mortgage + $349.00 auto loan + $348.00 credit cards). To achieve a dti ratio of 36%, his total monthly debt payments should be no more than $1,728.00 ($4,800.00 * 36%).

Therefore, he needs to reduce his monthly credit card payment by $219.00 ($1,947.00 - $1,728.00). Since his current minimum monthly credit card payment is $348.00, he needs to reduce it to d) $129.00 ($348.00 - $219.00) to reach his dti goal.

Two events, E1 and E2, are defined for a random experiment. What is the probability that at least one of the two events occurs in any trial of the experiment?

Answers

P(E1) + P(E2) - P(E1 ∩ E2) is the probability that at least one of the two events occurs in any trial of the experiment.

The correct answer is D. P(E1) + P(E2) - P(E1 ∩ E2).

The probability that at least one of two events occurs can be calculated using the principle of inclusion-exclusion.

The formula for this is:

P(E1 or E2) = P(E1) + P(E2) - P(E1 and E2)

Where:

P(E1) is the probability of event E1 occurring.

P(E2) is the probability of event E2 occurring.

P(E1 and E2) is the probability of both events E1 and E2 occurring simultaneously.

This formula represents the probability that at least one of the two events (E1 or E2) occurs in any trial of the experiment.

It's derived using the principle of inclusion-exclusion.

P(E1) represents the probability of event E1 occurring.

P(E2) represents the probability of event E2 occurring.

P(E1 ∩ E2) represents the probability of both events E1 and E2 occurring simultaneously.

By adding the probabilities of each individual event and then subtracting the probability of their intersection, you're accounting for the possibility of double-counting the intersection when adding the probabilities of the individual events.

So, the formula accurately captures the probability of at least one of the two events occurring.

Hence, P(E1) + P(E2) - P(E1 ∩ E2) is the probability that at least one of the two events occurs in any trial of the experiment.

The correct answer is D. P(E1) + P(E2) - P(E1 ∩ E2).
