If the profit desired is $24,000 and the revenue is $112,250, then the cost is $88,250.

To find the cost, we need to use the formula:

Revenue - Cost = Profit

We can rearrange this formula to solve for the cost:

Cost = Revenue - Profit

Substituting the given values, we get:

Cost = $112250 -$ 24000

Cost = $88250

Therefore, the cost is $88250.

Answer:

Danielle will need 27 gallons of blue paint.

Step-by-step explanation:

If the shade of green paint requires 2 parts yellow and 3 parts blue, that means for every 2 gallons of yellow paint, we need 3 gallons of blue paint.

So to find how many gallons of blue paint Danielle will need, we can set up a proportion:

2/3 = 18/x

where x is the number of gallons of blue paint.

To solve for x, we can cross-multiply:

2x = 54

x = 27

Therefore, Danielle will need 27 gallons of blue paint.

Answer:  To make the special shade of green paint, Danielle needs 2 parts yellow and 3 parts blue. This means that for every 2 gallons of yellow paint, she needs 3 gallons of blue paint.

If Danielle uses 18 gallons of yellow paint, we can set up a proportion to find how many gallons of blue paint she needs:

2/3 = 18/x

where x is the number of gallons of blue paint she needs.

To solve for x, we can cross-multiply and simplify:

2x = 3 * 18

2x = 54

x = 27

Therefore, Danielle will need 27 gallons of blue paint to make the special shade of green paint.

Answer:

Step-by-step explanation:

To find the perimeter of the classroom, we need to calculate the distance between each pair of adjacent corners and add them up.

Using the distance formula, the distance between the first two corners is:

√[(-12 - (-12))^2 + (15 - (-9))^2] = √(0^2 + 24^2) = 24 feet

The distance between the second and third corners is:

√[(-12 - 9)^2 + (-9 - 15)^2] = √(21^2 + 24^2) ≈ 31.8 feet

The distance between the third and fourth corners is:

√[(9 - 9)^2 + (15 - (-9))^2] = √(0^2 + 24^2) = 24 feet

Finally, the distance between the fourth and first corners is:

√[(9 - (-12))^2 + (-9 - 15)^2] = √(21^2 + 24^2) ≈ 31.8 feet

Therefore, the perimeter of the classroom is:

24 + 31.8 + 24 + 31.8 = 111.6 feet ≈ 112 feet (rounded to the nearest foot)

So the closest option to this answer is 90 feet.

The rate at which the depth is changing at 2 am is given as follows:

D'(2) = 0.4354 feet per hour.

The equation giving the depth of the water in t hours after midnight is given as follows:

D(t) = 2cos(πt/3 + 2π/5) + 3.

The derivative of the cosine is negative sine, while the inner derivative is of π/3, hence, applying the chain rule, the derivative is given as follows:

D'(t) = -2π/3sin(πt/3 + 2π/5)

2 am is 2 hours after midnight, hence the numeric value of the derivative is given as follows:

D'(2) = -2π/3sin(2π/3 + 2π/5)

D'(2) = 0.4354 feet per hour.

The equation of the oblique asymptote of g(x) = x²+x+4/x-1 is y=x+1.

Synthetic division is a shorthand method for dividing polynomials. It is similar to long division, but simplified by removing all the steps except for the division, such as a linear factor with a leading coefficient of one.

To find the equation of the oblique asymptote, we need to divide the numerator (x²+x+4) by the denominator (x-1) using synthetic division.

To do this, we must first create a synthetic division setup, as shown above. The first number in the setup is the number that is being divided by the polynomial in the denominator.

In this case, it is 1. The other numbers in the setup are the coefficients of the polynomial in the numerator.

The synthetic division setup has 1 as the number being divided and 1, 1, and 4 as the coefficients of the numerator.

After dividing, the quotient is x+1 and the remainder is 0. Since the remainder is 0, the equation of the oblique asymptote is y = x+1.

This means that the line with the equation y = x+1 is the oblique asymptote of g(x) = x²+x+4/x-1.

The value of x in the right triangle is 10.43 units.

A right triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in the triangle is 180 degrees. Therefore, let's find the value of x in the right triangle.

tan 41 = opposite / adjacent

opposite side = x

The domain and range of y = Q(-t) are [-3,-1] and [-4,7], respectively.

The domain and range of y = -Q(t) are [1,3] and [-7,4], respectively.

The domain and range of y = -Q(-t) are [-3,-1] and [-4,7], respectively.

a) In the domain of Q(t), we must replace t with -t for the transformation y = Q(-t). The domain of y = Q(-t) will be [-3,-1] because the domain of Q(t) is [1,3]. The range of Q(t), which is [-4,7], will not change.

As a result, the domain and range of y = Q(-t) are [-3,-1] and [-4,7], respectively.

b) For the transformation y = -Q(t), we must take the negative of Q(t)'s range. Because Q(t) has a range of [-4,7], y = -Q(t) has a range of [-7,4]. The domain of Q(t), [1,3], will remain unchanged.

As a result, the domain and range of y = -Q(t) are [1,3] and [-7,4], respectively.

c) We must take the negative for the transformation y = -Q(-t). in the domain of Q(t) and replace t with -t in the range of Q(-t). Because Q(t) has the domain [1,3], Q(-t) has the domain [-3,-1]. Reflecting the range of Q(t) about the y-axis yields the range of Q(-t). As a result, the range of Q(-t) is [-7,4]. Taking the inverse of the range, we get [-4,7] for y = -Q(-t).

As a result, the domain and range of y = -Q(-t) are [-3,-1] and [-4,7], respectively.

Answer: 58.72 degrees Celsius.

Step-by-step explanation:

We can use the following formula to estimate the temperature of the coffee when t = 10:

T(t) = T(room) + [T(initial) - T(room)] * e^(-r(t) * t)

where T(t) is the temperature of the coffee at time t, T(room) is the temperature of the room, T(initial) is the initial temperature of the coffee, and r(t) is the rate of change of the coffee's temperature.

Substituting the given values, we get:

T(10) = 20 + [90 - 20] * e^(-(-7 e^(-0.1 * 10)) * 10)

T(10) = 20 + 70 * e^(0.7)

T(10) ≈ 58.72 degrees Celsius (rounded to two decimal places)

Therefore, the estimated temperature of the coffee when t = 10 is 58.72 degrees Celsius.

The average speed at which the canoe traveled toward the lighthouse was approximately 14.1 feet per minute.

We can solve this problem using trigonometry. Let's call the distance between the canoe and the lighthouse "x", and let's call the average speed of the canoe "s".

From the first measurement, we know that:

tan(6.5°) = (115 - 1.3) / x

x = (115 - 1.3) / tan(6.5°)

x ≈ 1012.6 feet

From the second measurement, we know that:

tan(48.7°) = (115 - 1.3) / (x - 5/60 * s)

x - 5/60 * s = (115 - 1.3) / tan(48.7°)

x ≈ 166.2 feet

Now we can use these two equations to solve for "s". We can start by solving the second equation for "x" and substituting the result into the first equation:

x = 5/60 * s + (115 - 1.3) / tan(48.7°)

x ≈ 5/60 * s + 80.2 feet

(115 - 1.3) / x = tan(6.5°)

x = (115 - 1.3) / tan(6.5°)

Substituting the first equation into the second equation and simplifying, we get:

5/60 * s + 80.2 = (115 - 1.3) / tan(6.5°)

Answer: D

Step-by-step explanation:

The speed of P when t = 3 seconds is  95.00 m/s

We can find the speed by finding the net force acting on the particle P. Let F_net be the net force acting on P, then we have:

F_net = F₁ + F₂

where:

F₁ = (-i + 2j)N

F₂ = the direction of the vector (i + j).

Let's find the magnitude and direction of F₂. We know that F_net is in the direction of the vector (i + 3j), so we can write:

F_net = F₂ + k(i + 3j)

where:

k = some constant. Since F₂ is in the direction of (i + j), we can write:

F₂ = a(i + j)

where:

a = constant.

Substituting the into the equation for F_net:

F_net = a(i + j) + k(i + 3j)

To find the values of a and k, we use the acceleration of P which is (31 + 9j) m/s². The net force on P is:

F_net = m*a

where m = the mass of P.

Equating the two expressions for F_net:

a(i + j) + k(i + 3j) = m(31 + 9j)

Expanding both sides:

(ai + aj) + (ki + 3kj) = 31m + 9mj

Equating the coefficients of i and j, we get two equations:

a + k = 31m (1)

a + 3k = 9m (2)

Solving these equations:

a = 9m

k = 22m

Substituting these values back into the expression for F_net, we have:

F_net = 9m(i + j) + 22m(i + 3j) = 31mi + 69mj

Now, we can use the equation for acceleration to find the mass of P:

F_net = m*a

31mi + 69mj = m(31 + 9j)

m = 31 / (31 + 9j) = 31 / (31 - 9i)

Next, we shall use the initial velocity and acceleration to find the velocity of P after 3 seconds.

Let v(t) be the velocity of P at time t, then:

v(t) = v(0) + a*t

where v(0) = 3i - 22j and

a = (31 + 9j) m/s²

Substituting t = 3 seconds:

v(3) = (3i - 22j) + (31 + 9j)(3)

= 96i - 1j

Therefore, the speed of P at t = 3 seconds is the magnitude of v(3):

v(3)| = ([tex]\sqrt{96^{2} }[/tex] + (-1)²) = [tex]\sqrt9217[/tex] = 95.00 m/s
