The amount of time it will take them when working together is 12/7 hours, or approximately 1.71 hours.

If Harry can paint a room in 3 hours, and Kerry can paint it in 4 hours, then we can use the formula for combined work (work rate) to find how long it will take if they work together. The formula is:

1/t = 1/t₁ + 1/t₂, where t is the time it takes for them to complete the work together, t₁ is the time it takes for Harry to complete the work alone, and t₂ is the time it takes for Kerry to complete the work alone.

Plugging in the values we have, we get:

1/t = 1/3 + 1/4.

Multiplying both sides of the equation by 12t, we get:

12 = 4t + 3t.

Simplifying, we get:

12 = 7t.

Dividing both sides of the equation by 7, we get:

t = 12/7.

Therefore, it will take Harry and Kerry 12/7 hours, or approximately 1.71 hours, to paint the room together.

No, it is not true that every pyramid is a prism, because they have different properties.

A pyramid is a solid shape that has a base and triangular faces that meet at a point called the apex. The base of a pyramid can be any polygon, such as a square, triangle, or rectangle. A pyramid is named according to the shape of its base. For example, a pyramid with a square base is called a square pyramid.

A prism, on the other hand, is a solid shape that has two identical bases that are parallel to each other and rectangular faces that connect the bases. The bases of a prism can also be any polygon, and a prism is named according to the shape of its bases. For example, a prism with a rectangular base is called a rectangular prism.

14 students were on the bus when it left River Street School.

To find out how many students were on the bus when it left River Street School, we need to work backwards from the end of the route and account for all the students that were picked up and dropped off along the way.

At the last stop, seven students were dropped off, leaving only the driver aboard. This means that there were 7 students on the bus before the last stop.

Before that, five kindergarten students boarded the bus at the Centerville after-school-program, which means that there were 7 - 5 = 2 students on the bus before the kindergarten students boarded.

Before that, ten students got off at the Centerville after-school-program, which means that there were 2 + 10 = 12 students on the bus before they got off.

Before that, the bus made six stops and let off one student at each stop, which means that there were 12 + 6 = 18 students on the bus before those stops.

Before that, three students got off at one stop, which means that there were 18 + 3 = 21 students on the bus before that stop.

Before that, the bus made four stops and dropped off two students at each stop, which means that there were 21 + (4 x 2) = 29 students on the bus before those stops.

Finally, before that, the bus picked up 15 students at the Park School, which means that there were 29 - 15 = 14 students on the bus when it left River Street School.

14 students were on the bus when it left River Street School.

Starting from the end of the route and working backwards, we accounted for all the students that were picked up and dropped off along the way.

The zeros of the polynomial p(x)=4x^(4)-15x^(3)+9x^(2)+16x-12 are approximately -0.764, 0.621, 2.572, and 3.071.

To find the zeros of the given polynomial p(x)=4x^(4)-15x^(3)+9x^(2)+16x-12, we need to solve the equation p(x)=0.

First, let's try to factor the polynomial. We can use the Rational Root Theorem to find the possible rational zeros of the polynomial. The possible rational zeros are ±1, ±2, ±3, ±4, ±6, and ±12.

Let's try each of these possible zeros until we find one that makes the polynomial equal to zero.

When we plug in x=1, we get p(1)=4(1)^(4)-15(1)^(3)+9(1)^(2)+16(1)-12=2, which is not equal to zero.

When we plug in x=2, we get p(2)=4(2)^(4)-15(2)^(3)+9(2)^(2)+16(2)-12=20, which is not equal to zero.

When we plug in x=3, we get p(3)=4(3)^(4)-15(3)^(3)+9(3)^(2)+16(3)-12=90, which is not equal to zero.

When we plug in x=-1, we get p(-1)=4(-1)^(4)-15(-1)^(3)+9(-1)^(2)+16(-1)-12=-30, which is not equal to zero.

When we plug in x=-2, we get p(-2)=4(-2)^(4)-15(-2)^(3)+9(-2)^(2)+16(-2)-12=4, which is not equal to zero.

When we plug in x=-3, we get p(-3)=4(-3)^(4)-15(-3)^(3)+9(-3)^(2)+16(-3)-12=-162, which is not equal to zero.

So, none of the possible rational zeros are actually zeros of the polynomial.

Therefore, the polynomial does not have any rational zeros. The zeros of the polynomial are irrational or complex numbers.

To find these zeros, we need to use a different method, such as the Quadratic Formula or synthetic division.

Unfortunately, these methods are beyond the scope of this answer. However, you can use a graphing calculator or an online polynomial solver to find the approximate values of the zeros.

The approximate zeros of the polynomial are -0.764, 0.621, 2.572, and 3.071.

So, the zeros of the polynomial p(x)=4x^(4)-15x^(3)+9x^(2)+16x-12 are approximately -0.764, 0.621, 2.572, and 3.071.

The answer is \(a+b+c+d = 10\).

To find \(a+b+c+d\), we can use matrix multiplication to solve for each variable. Matrix multiplication is performed by multiplying the elements of each row of the first matrix by the corresponding elements of each column of the second matrix, and then summing the products.

So, we can set up the following equations:

\(10 = 1a + 2c\)

\(1 = 1b + 2d\)

\(-6 = 3a - 3c\)

\(-6 = 3b - 3d\)

Solving for each variable, we get:

\(a = 6 - 2c\)

\(b = (1 - 2d)/1\)

\(c = (6 + 3a)/(-3)\)

\(d = (3b + 6)/(-3)\)

Substituting the values of \(a\) and \(b\) into the equations for \(c\) and \(d\), we get:

\(c = (6 + 3(6 - 2c))/(-3)\)

\(d = (3((1 - 2d)/1) + 6)/(-3)\)

Solving for \(c\) and \(d\), we get:

\(c = -2\)

\(d = -1\)

Substituting these values back into the equations for \(a\) and \(b\), we get:

\(a = 6 - 2(-2) = 10\)

\(b = (1 - 2(-1))/1 = 3\)

So, \(a+b+c+d = 10 + 3 + (-2) + (-1) = 10\).

Therefore, the answer is \(a+b+c+d = 10\).

2(cot2 y + tan2 y) = 2(1) Verified

Verify the identity:

2 sec2 y - 2 cot2 y = cot(2y) - 2 cot(2y) = 2 - 2 sec(2y)

To prove the identity, start by applying the identity:

cot2 y = 1 - tan2 y

Substitute this in the left side of the equation:

2 sec2 y - 2(1 - tan2 y) = 2 sec2 y - 2 + 2 tan2 y

Simplify the equation by factoring out a 2 from the right side:

2 sec2 y - 2 + 2 tan2 y = 2(sec2 y - 1 + tan2 y)

Next, apply the identity:

sec2 y - 1 = cot2 y

Substitute this in the equation and simplify:

2(sec2 y - 1 + tan2 y) = 2(cot2 y + tan2 y)

Finally, apply the identity:

cot2 y + tan2 y = 1

Substitute this in the equation and simplify:

2(cot2 y + tan2 y) = 2(1)

y = 3sin(πt). This function models the oscillation by representing the distance in centimeters from the equilibrium position as the sine of π multiplied by the time in seconds.

y = 3sin(πt). This function can be used to model the oscillation because it represents the distance in centimeters from the equilibrium position as the sine of π multiplied by the time in seconds. This means that for any given value of t, the value of y will be the sine of π multiplied by t, which will correspond to a certain distance from the equilibrium position. As the oscillation has a frequency of 1 cycle per second, the value of t will increase linearly, and the value of y will oscillate between a maximum and a minimum value. As the distance between the maximum and minimum points of the oscillation is 3 centimeters, the maximum and minimum values of y will be 3 when t is an integer multiple of π. Therefore, the function y = 3sin(πt) can be used to accurately model the oscillation.

Answer:

$35,734.12

Step-by-step explanation:

To determine the amount Joe must deposit now to have $75,000 in 18 years, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where:

A is the future value we want to have ($75,000 in this case)

P is the present value we need to deposit now

r is the annual interest rate (3.75%)

n is the number of times interest is compounded per year (12 for monthly compounding)

t is the number of years (18)

Substituting the given values, we get:

$75,000 = P(1 + 0.0375/12)^(12*18)

Simplifying the exponent:

$75,000 = P(1.003125)^216

Dividing both sides by (1.003125)^216:

P = $75,000 / (1.003125)^216

P ≈ $35,734.12

Therefore, Joe must deposit approximately $35,734.12 now to have $75,000 in 18 years at an interest rate of 3.75% compounded monthly.
