The value of x in the equation y = 9 sec(2x) at [0, π/4) ∪ (π/4, π/2] is x = 1/2[sec₋¹(y/9)]

Calculating the values of x

From the question, we have the following parameters that can be used in our computation:

y = 9 sec(2x)

The interval of x is also given as

[0, π/4) ∪ (π/4, π/2]

This means that the values of x is from 0 to π/2, however, the function is undefined at x = π/4 i.e. there is a hole at x = π/4

Next, we set the equation to y

So, we have

9 sec(2x) = y

Divide both sides by 9

sec(2x) = y/9

Take the arc sec of both sides of the equation

2x = sec₋¹(y/9)

Divide both sides by 9

x = 1/2[sec₋¹(y/9)]

Hence, the value of x is x = 1/2[sec₋¹(y/9)]

Types of discontinuities

Identify and Classify the discontinuities in the function, please

Answers

The discontinuity at x = -2 is a removable discontinuity or a hole in the graph of the function.

To identify the discontinuities in the function f(x), we first need to find the values of x that make the denominator zero, since division by zero is undefined.

The denominator of f(x) is x² + x - 2, which can be factored as (x - 1)(x + 2). Therefore, the function f(x) is undefined at x = 1 and x = -2, since they would make the denominator zero.

Now we need to determine the type of discontinuity at these points.

At x = 1, the function f(x) approaches infinity as x approaches 1 from both sides of the graph.

At x = -2, the function f(x) has a hole in the graph.

This means that the function is undefined at x = -2, but if we "plug in" x = -2, we can factor the numerator and cancel out the common factor with the denominator, resulting in a new function that is continuous at x = -2. The new function is:

f(x) = (x⁴ - 5x² + 4) / (x² + x - 2)

= [(x² - 1)(x² - 4)] / [(x - 1)(x + 2)]

= (x - 1)(x + 1)(x - 2), for x ≠ -2

Therefore, the discontinuity at x = -2 is a removable discontinuity or a hole in the graph.

12 A quality control inspector at a plant has found the probability of randomly selecting a defective
battery from a batch of batteries being produced is 0.02. The probability of rain that day has been
projected to be 0.75. If these two events are independent, what is the probability that on that particular
day, it rains, and the inspector chooses a defective battery from the batch being produced?
(1) 0.77
(3) 0.015
(2) 0.5
(4) 0.95

Answers

Answer:

The answer is (3) 0.015.

Step-by-step explanation:

This is because to find the probability of finding both independent events happening at the same time, we must multiply them.

The independent events are:

- Randomly selecting a defective battery: 0.02

- Raining tomorrow: 0.75

0.02 x 0.75 = 0.015

Therefore, the answer is (3) 0.015.

If Kayla has a 73% in her history class and she took a test 20% of her grade and got a 60 on it. What would her grade be?

Answers

Answer:

70.4%

Step-by-step explanation:

Assuming the test is the only graded assignment, and the remaining 80% of her grade is still at 73%, we can calculate Kayla's new overall grade as follows:

New overall grade = (0.80 x 73) + (0.20 x 60)

New overall grade = 58.4 + 12

New overall grade = 70.4

Therefore, Kayla's new overall grade is 70.4%

Answer:

70.4% or a C-.

Step-by-step explanation:

To calculate Kayla's new grade after taking the test, you need to first find out what percentage of her overall grade the test is worth. If the test is worth 20% of her grade, then the remaining 80% of her grade is based on other factors, such as homework, quizzes, and other tests.

To calculate Kayla's new grade, you can use the following formula:

New grade = (Current grade x Weight of current assignments) + (Grade on test x Weight of test)

Plugging in the numbers given in the problem, we get:

New grade = (0.73 x 0.80) + (0.60 x 0.20)

New grade = 0.584 + 0.12

New grade = 0.704

Therefore, Kayla's new grade after taking the test would be approximately 70.4%, or a C-.

If the ratio of a circle's circumference to the circle's area is 2/9, then find the circles area.

Answers

The area of the circle is 81π. Option A.

What is area of a circle?

The area of a given circle is the amount of space that the circle will cover when considered in a 2 dimensional plane. It can be determined by;

area of a circle = πr^2

where r is the radius.

The circumference of a circle is the curved boundary of a circle. It can be determined by;

circumference of a circle = 2πr

where r is its radius.

From the given information in the question, we have a circle's circumference to the circle's area;

circumference/ area = 2/ 9

But,

circumference/ area = 2πr/ πr^2

                                  = 2/ r

Then;

2/ r = 2/ 9

2r = 2*9

   = 19

r = 18/ 2

r = 9

Thus,

area of the circle = πr^2

                             = π(9)^2

                             = 81π

Answers

According to the information, Hannah donated b/50 books in total.

How  to calculate how many books did Hannah donate?

First, we need to find the average number of books donated by each student. We can do this by dividing the total number of books donated by the number of students:

average number of books per student = b / 150

Hannah donated 3 times this amount, so we can multiply the average by 3 to find how many books she donated:

Hannah's donation = 3 * (b / 150)

Simplifying this expression, we get:

Hannah's donation = b / 50

Therefore, Hannah donated b/50 books in total.

(d) $35.70​

Answers

Jim must pay tax  $3.57.

The correct answer is (a) $3.57.

To calculate the sales tax that Jim must pay, we need to find 7% of the total cost of the shoes and laces.

The total cost of the shoes and laces is $50 (shoes) + $1 (laces) = $51.

To calculate the sales tax, we multiply the total cost by the tax rate:

Sales tax = 7% of $51

[tex]= 0.07 \times $51[/tex]

= $3.57.

Therefore, Jim must pay $3.57 in sales tax.

Answers

The calculated values of the angle measures when converted to radians are 1.31π rad and 3.34π rad

Converting the angle measures to radians.

To convert angles from degrees to radians, we multiply the number of degrees by π/180.

This means that

Angle = Degree measure * π/180

Using the above as a guide, we have the following:

Angle 236 = 236 * π/180

Evaluate the products

Angle 236 = 1.31π rad

Next, we repeat the same process for the second angle 601 degrees

Angle 601 = 601 * π/180

Evaluate the products

Angle 601 = 3.34π rad

A local store was offering a discount of 25% on original parice on older model laptops. Gina bought an older model laptop for $963 that includes a 7% tax on the discounted price

Answers

Answer:

Step-by-step explanation:To solve this problem, we need to work backwards from the final price that Gina paid and determine the discounted price before tax was added.

Let x be the original price of the laptop. After a 25% discount, the discounted price is:

Discounted price = x - 0.25x = 0.75x

Next, we add 7% tax to the discounted price:

Final price = (0.75x) + 0.07(0.75x) = 0.8025x

We know that the final price that Gina paid was $963, so we can set up an equation:

0.8025x = 963

Solving for x, we get:

x = 1200

Therefore, the original price of the laptop was $1200, and the discounted price before tax was:

Discounted price = 0.75x = 0.75(1200) = $900

To check, we can add the 7% tax to the discounted price:

Final price = $900 + 0.07($900) = $963

This matches the price that Gina paid, so we can be confident in our answer.

In how many distinct ways can the digits in the number 2,563,183,083 be arranged?
(If there are any zero digits then assume they can be placed in any position)

Answers

There are 10 digits in the number 2,563,183,083. If we ignore the fact that there are three occurrences of the digit 3 and two occurrences of the digit 8, then there would be 10! = 3,628,800 distinct ways to arrange the digits.

However, we need to account for the fact that three of the digits are 3s and two of the digits are 8s. To do this, we need to divide out the number of arrangements of those duplicates.

There are 3! = 6 ways to arrange the three 3s among themselves, and 2! = 2 ways to arrange the two 8s among themselves. So, we divide the total number of arrangements by these permutations of the duplicates:

10! / (3! * 2!) = 10 x 9 x 8 x 7 x 6 x 5 x 4 = 604,800

Therefore, there are 604,800 distinct ways to arrange the digits in the number 2,563,183,083, assuming that any zero digits can be placed in any position.

Of the 22 students in a classroom, 10 are transfer students, 7 are nursing students, 4 are AAS students and 1 student is undecided. If 5 students are chosen randomly, with replacement, find the probability that at least one student is a transfer student.

Answers

To solve this problem, we can use the complement rule, which states that the probability of an event occurring is equal to 1 minus the probability of the event not occurring. In this case, we want to find the probability that at least one student is a transfer student, so we can find the probability that no students are transfer students and subtract that from 1.

The probability that a randomly chosen student is not a transfer student is 12/22, since there are 12 students who are not transfer students out of a total of 22 students. Therefore, the probability that none of the 5 students chosen are transfer students is:

(12/22)^5 = 0.068

To find the probability that at least one student is a transfer student, we can subtract this from 1:

1 - 0.068 = 0.932

Therefore, the probability that at least one student is a transfer student is 0.932.

Answers

We can evaluate log_10^3 using the definition of logarithms:

log_b(x) = y if and only if b^y = x

In this case, we have log_10^3, which means that 10 is the base and 3 is the argument. We want to find the exponent y such that 10^y = 3.

However, there is no integer exponent that satisfies this equation, since 10^1 = 10 and 10^2 = 100 are both greater than 3, while 10^0 = 1 is less than 3.

Therefore, the value of log_10^3 is not an integer and cannot be expressed in the form of one of the answer choices. We can, however, approximate the value of log_10^3 as approximately 0.477, using a calculator or logarithm table.

The design includes four plot types: dry with native only, dry with exotic only, dry with both algae, and wet with both algae. When grown together on dry plots, the native grew well while the exotic went extinct. When grown together on wet plots, the exotic grew well while the native went extinct. Both algae grew in dry plots when grown alone. You note that his experimental design is incomplete and, as a result, he cannot support one of the following conclusions. Which conclusion is NOT supported?a. Dry habitats are part of the fundamental niche of the native alga. b. Dry habitats are part of the fundamental niche of the exotic alga. c. The native alga competitively excludes the exotic alga in dry habitats. d. The exotic alga competitively excludes the native alga in wet habitats Write the coordinates of the vertices after a reflection over the x-axis.yx-1010-10100TUVT(-1, 7) T(, )U(-1, 8) U(, )V(9, 6) V(, ) The table shows the home state of the 175 high school students who attended a tri-state debate tournament.
