what is the volume of the prism?

Vertex A: (90°, 3) and Vertex B: (90°, -1) of the sine function.

The vertex A of the curve y = sin x + 2 is obtained by shifting the vertex of y = sin x upward by 2 units. Since the vertex of y = sin x is (90°, 1), the vertex of y = sin x + 2 will be:

A = (90°, 1 + 2) = (90°, 3)

Therefore, the coordinates of the vertex A of the curve y = sin x + 2 are (90°, 3).

b) The curve y = -sin x is obtained by reflecting the curve y = sin x about the x-axis. Since the vertex of y = sin x is (90°, 1), the vertex of y = -sin x will be:

A = (90°, -1)

Therefore, the coordinates of the vertex A of the curve y = -sin x are

(90°, -1).

The domain of f(x) is equal to the range of inverse function g(x).

What are inverse functions?

A function from a set X to a set Y in mathematics assigns each element of X the exact same number of elements from Y. A function's inverse function reverses the action of a function or f. If and only if the function is bijective, the inverse of f is true.

Given two functions f(x) and g(x).

It is also said that g(x) is the inverse of f(x).

One of the properties of inverse functions is that only one-to-one functions are inverse. If g is equal to f's inverse, then f is equal to g's inverse.

Both f and g are one-to-one functions if they are the inverses of one another.

f and g are inverses of each other if (fog)(x) = x, x ∈ the domain of g.

The range of g equals the domain of f, and the domain of f equals the range of g.

Therefore the domain of f(x) is equal to the range of inverse function g(x).

The zeros of the polynomial function f(x) are:

x = -1, -3/2, -2 + i/2, -2 - i/2

To find the complex zeros of the given polynomial function f(x), we can use the fact that every polynomial with complex coefficients has at least one complex zero.

First, we can use the Rational Zeros Theorem to find any rational zeros. The possible rational zeros are of the form p/q, where p is a factor of the constant term 45 and q is a factor of the leading coefficient 2. Therefore, the possible rational zeros are ±1, ±3/2, ±5, ±9/2, ±15, and ±45/2. We can test each of these values using synthetic division or long division to see if they are actually zeros of the polynomial.

Using long division, we find that x=−1 and x=−3/2 are zeros of the polynomial. Therefore, we can factor out (x+1) and (x+3/2) from the polynomial to get:

f(x) = (x+1)(x+3/2)(2x^3+8x^2+14x+30)

Next, we can use the quadratic formula to find the zeros of the cubic factor 2x^3+8x^2+14x+30. The quadratic formula gives:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 2, b = 8, and c = 15. Plugging in these values, we get:

x = (-8 ± sqrt(8^2 - 4(2)(15))) / 4

= (-8 ± 2i) / 4

= -2 ± i/2

These are the exact values of the complex zeros of the polynomial function.

No, since interval contains 0, thus the difference between boys and girls is not significant.

This can be solved using the concept of standard deviation.

Data dispersion in regard to the mean is quantified by a standard deviation, or "σ". Data are said to be more closely grouped around the mean when the standard deviation is low and more dispersed when the standard deviation is high.

Because it makes measures easier to comprehend when the data is spread, standard deviation is significant. The data's standard deviation will increase as the data's distribution becomes more widely scattered.

We have given,

n₁ = 200,    n₂ = 150

x₁ = 48.4     x₂ = 48.9

s₁ = 12.96    s₂ = 11.85

95% confidence interval for difference of mean scores of boys and girls

since, n₁ and n₂ are very large therefore we may use standard normal variate , thus 95% CI is given by:

x₁ - x₂ ± 2μ₂ √(s₁²/n₁ + s₂²/n₂)

now, 2μ₂ = 1.96

∴ CI = (48.4 - 48.9) ± 1.96 √(12.96)²/ 200 + (11.85)²/150

or, CI = (-3.119, 2.1119)

Area and Perimeter of Similar Polygons:

Polygons are said to be similar when their corresponding angles are equal and their corresponding sides are in the same proportion. The perimeters and areas of identical polygons have a unique relationship, just as their corresponding sides do.

Perimeters: The scale factor and the perimeters ratios of perimeters are similar. In reality, the scale factor is identical to any ratio between any two similar forms (diagonals, medians, midsegments, altitudes, etc.).

Areas: If the scale factor of the sides of two similar polygons is [tex]\frac{m}{n}[/tex]

, then the ratio of the areas is [tex](\frac{m}{n} )^{2}[/tex].

(Area of Similar Polygons Theorem). Because area is a two-dimensional quantity, you square the ratio.

It is given that ,

the ratio of perimeters of two similar quadrilateral is 2:4.

now,

to find the ratio of area , we can take two quadrilaterals, say square.

Square ABCD of side 2 units and Square PQRS of side 4 units.

now ratio of areas,

[tex]=\frac{area of square ABCD}{area of square PQRS} \\\\=\frac{2*2}{4*4} \\\\=\frac{4}{16}[/tex]

If the given ratio of perimeters can be further solved as 1:2, then we can see that the ratio of areas can also be further solved as 1:4.

Step-by-step explanation:

Answer:

Step-by-step explanation:

The system of equations can be written as a matrix and then used to solve for the variables x, y, and z.

The augmented matrix of the system is:

-3 -2  1 | -8

0  4 -2 | -8

0  0  7 | 26

We can use row operations to find the row reduced echelon form of the matrix, which will give us the solutions to the system.

Starting with the first row:

1. Multiply row 1 by -3 to get a leading 1 in the first column:

3  6 -3 | 24

0  4 -2 | -8

0  0  7 | 26

2. Add row 1 to row 2:

3  6 -3 | 24

0  4  0 | 16

0  0  7 | 26

3. Add 3 times row 1 to row 3:

3  6 -3 | 24

0  4  0 | 16

0  0  7 | 26

The row reduced echelon form of the matrix is:

1  2 -1 | 8

0  1  0 | 4

0  0  1 | 9

From this, we can see that the solutions to the system are:

x = 8 - 2y

y = 4

z = 9

So the system has a unique solution: x = 8 - 2y = 8 - 2 * 4 = 0, y = 4, z = 9.

22 feet

Step-by-step explanation:

As the given measurements are not all in the same units, convert all measurements to inches using the conversion 1 ft = 12 inches:

Therefore:

Draw a diagram using the given information (see attachment).

From the diagram, we can see that the flagpole and the person are parallel.  Therefore, the two triangles are similar.

In similar triangles, corresponding sides are always in the same ratio.

Therefore, set up a ratio of height to shadow length and solve for h:

[tex]\implies \sf Flagpole\;height:Flagpole:shadow=Person\;height:Person\;shadow[/tex]

[tex]\implies \sf h:168=66:42[/tex]

[tex]\implies \sf \dfrac{h}{168}=\dfrac{66}{42}[/tex]

[tex]\implies \sf h=\dfrac{66}{42} \cdot 168[/tex]

[tex]\implies \sf h=\dfrac{11088}{42}[/tex]

[tex]\implies \sf h=264\;inches[/tex]

Convert the height into feet by dividing by 12:

[tex]\implies \sf h=\dfrac{264}{12}=22\;feet[/tex]

Therefore, the height of the flagpole is 22 feet.

The following statements are true:

A:The car makes a complete revolution in 10 seconds

B:The maximum height of the Ferris wheel is 65 feet

A full rotation or turning around a focal point is referred to as a revolution. Revolution is the act of rotating around a fixed point or axis . Examples of this include the rotation of a planet around its star or a wheel around its axle.

A. The car makes a complete revolution in 10 seconds:

This can be deduced from the fact that the height of the Ferris wheel car returns to 35 feet after 10 seconds, which means that it has completed one full revolution.

B. The maximum height of the Ferris wheel is 65 feet:

This can be seen from the table, where the height of the Ferris wheel car reaches 65 feet at 2.5 seconds and 12.5 seconds.

C. If the car is loaded at 0 seconds, then the people are loaded at the lowest point of the Ferris wheel: This can be seen from the table, where the height of the Ferris wheel car is 35 feet at 0 seconds.

The profit the PTO makes from selling raffle tickets can be calculated by subtracting the cost of the tickets from the total revenue generated from ticket sales.

Let's first calculate the total revenue:

Number of tickets sold = 200

Price per ticket = $4

Total revenue = 200 * $4 = $800

Next, let's calculate the cost of the tickets:

Number of tickets sold = 200

Price per ticket = $4

Total cost = 200 * $4 = $800

Finally, we can calculate the profit by subtracting the cost of the tickets from the total revenue:

Profit = Total revenue - Total cost

Profit = $800 - $800 = $0

So, the PTO makes no profit from selling the raffle tickets. This is because the cost of the tickets and the prize are equal, and there are no other expenses. In this scenario, the prize money of $76 is given away to the winner, so the PTO does not get to keep the money for classroom supplies.

a. The number of ounces of oat flakes in the box is 15 ounces - a ounces, or 15 - a ounces.

b. The cost of the almonds (in cents) is 30 cents * a ounces, or 30a cents.

c. The cost of the oat flakes (in cents) is 15 cents * (15 - a) ounces, or 15 * (15 - a) cents.

d. The total cost of a box of Almond Oats (in cents) is the cost of the almonds plus the cost of the oat flakes, or 30a + 15 * (15 - a) cents.

The correct answer is that the probability is 2/3. To see why, we can count the number of codes that do not have D in the first position, which is 6 (two options for the first position, and three options for the second position).

The size of the sample space is 4 options for the letter, 2 options for the first number, and 1 option for the second number, giving a total of 4x2x1=8 possible codes. To calculate the probability that a code has a letter that immediately follows an odd number, we first need to count the number of codes that meet this condition. There are two odd numbers to choose from (5 and 6), and two letters that can immediately follow an odd number (B and D). For each odd number, there is only one even number that can come before it, so there are 2x1x2=4 possible codes that meet this condition. Therefore, the probability that a randomly chosen code has a letter that immediately follows an odd number is 4/8, which simplifies to 1/2, or 0.5. To calculate the probability that D is in the code but is not in the first position, we need to count the number of codes that meet this condition. There are two places that D could appear (second or third), and three options for the first position (A, B, or C). Once the first position is chosen, there are two options for the remaining number (5 or 6). Therefore, there are 2x3x2=12 possible codes that meet this condition. The total number of possible codes is 8, so the probability that a randomly chosen code has D but not in the first position is 12/8, which simplifies to 3/2, or 1.5. However, probabilities must always be between 0 and 1, so this answer is not valid.

The correct answer is that the probability is 2/3. To see why, we can count the number of codes that do not have D in the first position, which is 6 (two options for the first position, and three options for the second

position). Of these 6 codes, 4 have D in the second position, and 2 have D in the third position. Therefore, the probability that a randomly chosen code has D but not in the first position is (4+2)/8, which simplifies to 2/3.

It is given that:

20% of the students earned an A in STA 2023.

12% of the students didn't bring their phones to class.

85% of the students who didn't bring their phones to class earned an A.

To answer the following questions, we assume whether all students took STA 2023 and brought their phones to class or not.

a) Let's assume that x% of the students earned an A and brought their phones to class. Then, since the remaining (100% - 12%) = 88% of students brought their phone to class but their grade is not specified, we can set up the following equation:

x% + 85% of 12% = 20%

x% + 0.102 = 0.20

x% = 0.098

Therefore, 9.8% of students earned an A and brought their phones to class.

b) Let's assume that y% of the students didn't earn an A and didn't bring their phones to class. Then, we can set up the following system of equations:

x% + y% = 100% - 12%

0.85*(12%) = y%

Solving for y, we get:

y% = 9.6%

Therefore, 9.6% of students didn't earn an A and didn't bring their phones to class.

STA 2023 is a course code used by some colleges and universities to refer to an introductory course in statistics.
