Let g(x) be continuous with g(0) = 3. g(1)
8, g(2) = 4. Use the Intermediate Value Theorem to ex-
plain why s(x) is not invertible.

Answers

Answer 1

The Intermediate Value Theorem states that if a function f(x) is continuous on a closed interval [a,b], and if M is any number between f(a) and f(b), then there exists at least one number c in the interval [a,b] such that f(c) = M.

In this case, we are given a continuous function g(x) with g(0) = 3, g(1) = 8, and g(2) = 4. Let s(x) be the inverse of g(x), which means that s(g(x)) = x for all x in the domain of g(x).

Suppose s(x) is invertible. Then for any y in the range of g(x), there exists a unique x such that g(x) = y, and therefore s(y) = x. In particular, let y = 5, which is between g(1) = 8 and g(2) = 4. By the Intermediate Value Theorem, there exists a number c in the interval [1,2] such that g(c) = 5.

However, this means that s(5) is not well-defined, since there are two values of x (namely c and s(5)) that satisfy g(x) = 5. Therefore, s(x) is not invertible.

The Intermediate Value Theorem states that if a function is continuous on a closed interval [a, b], and k is any number between f(a) and f(b), then there exists a number c in the interval [a, b] such that f(c) = k.

Let g(x) be continuous with g(0) = 3, g(1) = 8, and g(2) = 4. Since g(x) is continuous, the Intermediate Value Theorem applies. However, to show that s(x) is not invertible, we need to show that g(x) is not one-to-one.

Notice that g(0) = 3 and g(2) = 4, with g(1) = 8 in between. This means that there must exist a point c1 in the interval (0, 1) such that g(c1) = 4, and another point c2 in the interval (1, 2) such that g(c2) = 3, due to the Intermediate Value Theorem.

Since g(c1) = g(c2) = 4 and c1 ≠ c2, g(x) is not one-to-one. Therefore, its inverse function s(x) does not exist, and s(x) is not invertible.

Answers

Solving the equation, Boris needs to read 34 novels in 17 months.

Given that Boris needs to read 2 novels each month.

To relate the number of novels Boris needs to read (n) to the number of months he has to read them (m), we can use the equation:
n = 2m

This equation states that the number of novels (n) is equal to two times the number of months (m) since Boris needs to read 2 novels each month.

Now, to find the number of novels Boris needs to read in 17 months, we can substitute m = 17 into the equation:
n = 2m
n = 2(17)
n = 34

Therefore, Boris needs to read 34 novels in 17 months to meet his goal of reading 2 novels each month.

If arc wvx=(13x+9) and angle wxz=(5x+36) find angle wxy

Answers

Angle WXY is vertical to angle WXZ, they are equal, therefore, angle WXY is also 141 degrees.

How to find the angle WXY using information about the arc WVX and angle WXZ in a circle?

To find the angle WXY, we need to use the properties of angles formed by intersecting chords in a circle. The angles formed by intersecting chords are related to the arcs intercepted by those chords.

Given that the arc WVX is equal to (13x + 9) and the angle WXZ is equal to (5x + 36), we can set up an equation:

Angle WXZ = [tex]\frac{1}{2}[/tex] * Arc WVX

(5x + 36) = [tex]\frac{1}{2}[/tex] * (13x + 9)

To solve for x, we'll multiply both sides of the equation by 2 to eliminate the fraction:

2(5x + 36) = 13x + 9

10x + 72 = 13x + 9

Subtracting 10x and 9 from both sides, we get:

72 - 9 = 13x - 10x

63 = 3x

Dividing both sides by 3, we find:

x = 21

Now that we have the value of x, we can substitute it back into the equation for the angle WXZ to find its value:

Angle WXZ = 5x + 36 = 5(21) + 36 = 105 + 36 = 141 degrees

Since angle WXY is vertical to angle WXZ, they are equal. Therefore, the angle WXY is also 141 degrees.

Answers

577 square feet is the area of the painted part of the wall.

To calculate the area of the painted part of the wall, you'll first need to find the total area of the wall and then subtract the areas of the windows and door. Let's assume the wall has a height of 33 ft and a width of 20 ft (since the other dimensions aren't provided).

1. Calculate the total area of the wall:
Area of wall = Height x Width = 33 ft x 20 ft = 660 sq ft

2. Calculate the areas of the windows and door:
Window A = 6 ft x 5 ft = 30 sq ft
Window B = 3 ft x 4 ft = 12 sq ft

Assume that selection is to be done without replacement Set up the problem as if it were to be solved, but do not solve. P(4 criminal justice majors selected) N​

Answers

The probability that each of the 4 is a criminal justice major is equal to 0.0003 (rounded to four decimal places).

The probability of selecting 4 criminal justice majors from a group of 125 students, without replacement,

Using the hypergeometric probability distribution.

Start by calculating the total number of ways to choose 4 students from the group of 125.

C(125,4) = 125! / (4! (125-4)!)

              = 125 x 124 x 123 x 122 / (4 x 3 x 2 x 1)

              = 9,691,375

Next, calculate the number of ways to choose 4 criminal justice majors from the group of 18.

C(18,4) = 18! / (4! (18-4)!)

           = 18 x 17 x 16 x 15 / (4 x 3 x 2 x 1)

           = 3060

Finally,

Probability of selecting 4 criminal justice majors

=  number of ways to choose 4 criminal justice majors / total number of ways to choose 4 students:

P(4 criminal justice majors selected) = C(18,4) / C(125,4)

⇒P(4 criminal justice majors selected) = 3060 / 9,691,375

                                                                = 0.0003157

Therefore, probability that each of the 4 students selected at random from the group of 125 students are criminal justice majors, without replacement is 0.0003 (rounded to four decimal places).

George says his bicycle has a mass of 15 grams. If he takes the front wheel off what could be the mass?

Answers

If George's bicycle has a mass of 15 grams, then it is highly unlikely that he has stated the correct mass, as 15 grams is an extremely low mass for a bicycle.

If George`s bicycle weighs 15 grams, what would be the resulting weight of it if he removes the front wheel?

Determine if the givens mass of 15 grams is reasonable for a bicycle.

A typical bicycle weighs anywhere from 7 to 15 kilograms. It is highly unlikely that a bicycle would weigh only 15 grams, as this is much lighter than the lightest bicycle ever made.

Therefore, it is reasonable to assume that George made a mistake and meant to say 15 kilograms instead of grams.

Calculate the mass of the bicycle without the front wheel.

Assuming the mass of the bicycle is 15 kilograms, removing the front wheel will decrease the mass slightly, but not by a significant amount.

The front wheel typically accounts for around 1-2 kilograms of the total mass of the bicycle, so removing it would leave a mass of approximately 14 kilograms.

However, assuming he made a mistake and meant to say 15 kilograms, then the mass of the bicycle without the front wheel would be approximately 14 kilograms.

Dylan has a square piece of metal that measures 17 inches on each side. He cuts the metal along the diagonal, forming two right triangles. What is the length of the hypotenuse of each right triangle to the nearest tenth of an inch?

Answers

The length of the hypotenuse of each right triangle to the nearest tenth of an inch is 24 inches.

Here, two right triangles with legs each measuring 17 inches are created when the square piece of metal is sliced diagonally.

We will apply the Pythagorean Theorem to find the length of the hypotenuse.

The Pythagorean theorem states that square of hypotenuse is equal to the sum of the squares of opposite side and adjacent side.

Now,

[tex]Hypotenuse^{2} = 17^{2}+ 17^{2} \\Hypotenuse^{2} =289+289\\Hypotenuse^{2} =578\\Hypotenuse=\sqrt{ 578}\\Hypotenuse=24.04[/tex]

⇒ Hypotenuse ≈ 24 inches (to the nearest tenth of an inch)

Therefore, the length of the hypotenuse of each right triangle to the nearest tenth of an inch is 24 inches.

Hanif is 14 years old. he plans to do up to 70% training intensity. while jogging, hanif took his resting pulse rate for two days in a row. so hanif found that his resting heart rate was 76 beats per minute. what is hanif's training pulse rate?​

Answers

Hanif's training pulse rate at 70% intensity is approximately 142 beats per minute.

To find Hanif's training pulse rate at 70% intensity, we first need to calculate his maximum heart rate (MHR) using the formula:

MHR = 220 - age

Substituting Hanif's age, we get:

MHR = 220 - 14 = 206

Next, we need to calculate Hanif's target heart rate (THR) range at 70% intensity. This range is between 70% and 85% of his MHR. To calculate the lower end of the range, we multiply his MHR by 0.7:

THR lower = 0.7 × MHR = 0.7 × 206 = 144.2 (rounded to one decimal place)

To calculate the upper end of the range, we multiply his MHR by 0.85:

THR upper = 0.85 × MHR = 0.85 × 206 = 175.1 (rounded to one decimal place)

So Hanif's target heart rate range at 70% intensity is between 144.2 and 175.1 beats per minute.

To find his training pulse rate, we add his resting pulse rate (76 beats per minute) to the percentage of his target heart rate range which corresponds to 70% intensity. This is given by:

Training pulse rate = resting pulse rate + (0.7 × (THR upper - resting pulse rate))

Substituting the values we calculated, we get:

Training pulse rate = 76 + (0.7 × (175.1 - 76)) ≈ 142

Therefore, Hanif's training pulse rate at 70% intensity is approximately 142 beats per minute.

Solve the following problems:
given: circle k(o), diameter us, mru=50°, mut=30°
find: m

Answers

The measure of angle M is 20°.

To solve the problem, we need to find the measure of angle M, given the information about Circle K with center O, diameter US, angle MRU = 50°, and angle MUT = 30°.

Step 1: Determine the relationship between angles MRU and MUT.
Since MRU and MUT are both inscribed angles in Circle K, they share the same intercepted arc, which is arc MU.

Step 2: Calculate the measure of arc MU.
The measure of an intercepted arc is twice the measure of the inscribed angle. Since angle MRU = 50°, the measure of arc MU will be 2 * 50° = 100°.

Step 3: Find the measure of angle M.
We know that angle MUT = 30°, and the measure of an intercepted arc is twice the measure of the inscribed angle. Therefore, the measure of arc MT = 2 * 30° = 60°. Now, since arc MU = 100°, we can determine the measure of arc MS (arc MS = arc MU - arc MT) which is 100° - 60° = 40°.

Step 4: Calculate the measure of angle M.
Finally, the measure of angle M can be found using the intercepted arc MS. Since the measure of an intercepted arc is twice the measure of the inscribed angle, angle M = 1/2 * arc MS = 1/2 * 40° = 20°.

Answers

There are 6 cute numbers in total which are 14, 19, 49, 55, 79, 85.To find the cute numbers, we need to check all numbers greater than 9 and see if they satisfy the cute condition.

Let's start by analyzing the digits of a number. Suppose the number has two digits, x and y. The cute condition requires:

x + y + xy = 10x + y

Rearranging this equation, we get:

xy - 9x = y - x

xy - x - y = -9x

(x - 1)(y - 1) = 9x - 1

For a number to be cute, the right-hand side of the equation must be divisible by the left-hand side. Since 9x - 1 is odd, the left-hand side must also be odd, which means one of the factors (x - 1) or (y - 1) must be odd and the other even.

We can now check all possible pairs of (x,y) that satisfy this condition. We find that the cute numbers are:

If Wendy is 63 inches tall and her hand is 6. 5 inches long, what is the residual if the formula to predict h, height in inches, from x, hand length in inches?

Answers

If the formula predicted Wendy's height to be 65 inches based on her hand length of 6.5 inches, the residual would be -2 inches

A residual is the difference between the predicted value of a variable (in this case, height) and the actual value of that variable. Residuals are often used in statistical analysis to assess the accuracy of a prediction or model.

In this case, if we were given the formula for predicting height from hand length, we could use it to predict Wendy's height and compare that to her actual height of 63 inches. The residual would be the difference between the predicted height and her actual height. If the prediction overestimated her height, the residual would be negative. If it underestimated her height, the residual would be positive.

For example, if the formula predicted Wendy's height to be 65 inches based on her hand length of 6.5 inches, the residual would be -2 inches (predicted height minus actual height). If the formula predicted her height to be 61 inches, the residual would be +2 inches.

Overall, residuals are a useful tool for assessing the accuracy of predictions or models, but the specific calculation of a residual depends on the formula being used to make the prediction.

b = 8z

Step-by-step explanation:

Expanding the given expression, we get:

(4y + z)^2 = (4y + z) × (4y + z)

= 16y^2 + 8yz + z^2

Comparing this with the general form of a quadratic expression, ax^2 + bx + c, we can see that:

a = 16

b = 8z

Therefore, the value of a is 16 and the value of b is 8z.

Engineers built an arch bridge across a river. The arch bridge


makes a parabola shape that has the equation


y=-0. 1(x – 5)2 + 12, where x and y are measured in


meters. If the bridge makes contact with both banks at a height


of 4 meters, how long is the distance between the two banks


of the river where the bridge is? Round your answer to the


nearest whole number.

Answers

To find the distance between the two banks of the river where the arch bridge is, we first need to determine the points where the bridge makes contact with the banks at a height of 4 meters.

We are given the parabola shape of the arch with the equation y = -0.1(x - 5)^2 + 12.

1. Set the height y equal to 4 meters:


4 = -0.1(x - 5)^2 + 12

2. Subtract 12 from both sides:


-8 = -0.1(x - 5)^2

3. Divide both sides by -0.1:


80 = (x - 5)^2

4. Take the square root of both sides:


sqrt(80) = x - 5

5. Now, we find the two x-values where the bridge contacts the banks:


x1 = sqrt(80) + 5


x2 = -sqrt(80) + 5

6. Calculate the distance between the two banks by subtracting x2 from x1:


Distance = x1 - x2 = (sqrt(80) + 5) - (-sqrt(80) + 5)

7. Simplify the expression:


Distance = 2 * sqrt(80)

8. Round your answer to the nearest whole number:


Distance ≈ 18 meters

The distance between the two banks of the river where the arch bridge is, is approximately 18 meters.

What is the measure of an angle that goes through 2/8 of a circle?

Answers

The measure of an angle that goes through 2/8 of a circle is 90°

A circle is a 2-dimensional shape that is round in shape it is equidistant from the center.

A circle has a total angle of 360°

That is the whole complete angle of the circle = 360°

The 2/8 th of the complete angle of the circle = 360 * 2/8

= 360 * 1/4

= 360/4

=90°

Thus, the 90° of the circle is given as 2/8th of an angle of the circle or we can say that the quarter angle of a circle comes out to 90°.

how do you know when to use the Rule of Sum or Fundamental Counting Principle for probability problems?

Answers

If the events are exclusive, use the Rule of Sum. If the events are independent, use the Fundamental Counting Principle.

The Rule of Sum and the Fundamental Counting Principle are two common methods used in probability to calculate the total number of possible outcomes. Knowing which method to use depends on the nature of the problem and the type of events involved.

The Rule of Sum is used when we have two or more exclusive events. This means that only one of the events can happen at a time. For example, when rolling a die, the events of rolling a 2 or a 4 are exclusive because you cannot roll both at the same time.

The rule of sum states that the total number of possible outcomes is the sum of the number of outcomes for each event.

On the other hand, the Fundamental Counting Principle is used when we have a sequence of events that are independent of each other. This means that the outcome of one event does not affect the outcome of the next event.

For example, when flipping a coin, the outcome of the first flip does not affect the outcome of the second flip. The fundamental counting principle states that the total number of possible outcomes is the product of the number of outcomes for each event.

Pls help with these two equations. Pls

Answers

Answer:

11. x = 16

12. x = 26

Step-by-step explanation:

11. ∠1 + ∠2 = 90°

   ∠1 = 42°

   ∠2 = 90° - 42° = 48°

   3x = 48

   x = 16

12. ∠C + ∠D = 180°

∠C = 128°

∠D = 180° - 128° = 52°

2x = 52

x = 26

1. If Cos A = 1/4, what is Sin B?

2. Simplify Sin A + Cos B ÷ 2

3. If Tan B = 1/5, what is Tan A? Which angle is bigger, angle A or angle B?

Please answer all 3

Answers

a. Sin A = opposite/hypotenuse = √15/4

b.  (Sin A + Cos B) ÷ 2 = (Sin A + Cos B)/2

c.  Tan A  = 1/5

The both angle could be of same size

How do we calculate?

Since Cos A = adjacent/hypotenuse,

Applying  the Pythagorean theorem,

we can find the opposite side:

opposite^2 + 1^2 = 4^2

opposite^2 = 16 - 1

opposite = √15

Now we can find the value of Sin A:

Sin A = opposite/hypotenuse = √15/4

b.

Sin A + Cos B = (Sin A) + (Cos B)

(Sin A + Cos B) ÷ 2 = (Sin A + Cos B)/2

c. Since Tan B = opposite/adjacent,  

we use  Pythagorean theorem to  find the hypotenuse:

hypotenuse^2 = 5^2 + 1^2

hypotenuse = √26

Tan A = opposite/adjacent = 1/5
