Suppose the Sunglasses Hut Company has a profit function given by P ( q ) = − 0.02 q 2 + 5 q − 30 , where q is the number of tho

Andrew [12]

Answer:

A) Pairs of sunglasses should be sold to maximize profits is 100 thousand.

B) The actual maximum profits that can be expected is 180 thousands dollars.

Step-by-step explanation:

Given : Suppose the Sunglasses Hut Company has a profit function given by $P(q)=-0.02q^2+4q-20$

where, q is the number of thousands of pairs of sunglasses sold and produced and P(q) is the total profit, in thousands of dollars, from selling and producing q pairs of sunglasses.

To find :

A) How many pairs of sunglasses (in thousands) should be sold to maximize profits?

Profit is $P(q)=-0.02q^2+4q-20$

Compare with general quadratic equation $ax^2+bx+c$

a=-0.02, b=4, c=-20

The maximum value of quadratic function is at $x=-\frac{b}{2a}$

So, maximum profit occur at q is given by,

$q=-\frac{4}{2(-0.02)}$

$q=\frac{4}{0.04}$

$q=100$

i.e. 100 thousand pair of sunglasses.

Pairs of sunglasses should be sold to maximize profits is 100 thousand.

B) What are the actual maximum profits (in thousands) that can be expected?

Maximum profit occurs at q=100 thousand pairs is given by,

$P(100)=-0.02(100)^2+4(100)-20$

$P(100)=-0.02\times 10000+400-20$

$P(100)=180$

The actual maximum profits that can be expected is 180 thousands dollars.

Melissa's boyfriend gave her a 2-pound heart-shaped box of chocolates. The box had 68 pieces of chocolate. What was the average

Kobotan [32]

The average weight in ounce for each piece of chocolate is 0.03.

Step-by-step explanation:

The heart-shaped box containing the chocolates has the weight of 2 pounds

The box contains 68 pieces of chocolates.To find the weight of each piece of chocolate, you divide the weight of the box with the number of chocolate pieces in the box.

This will be 2/68 = 0.0294117647

To the nearest hundredth you check the thousandths value and round off

In this case; 0.0294117647 = 0.03 pounds

Pedro has created the function f(x)= 4x-3/2 to represent the number of assingments he has completed where x represents the numbe

Law Incorporation [45]

The given function is
f(x) = 4x - 3/2
where
f(x) = number of assignments completed
x = number of weeks required to complete the assignments

We want to find f⁻¹ (30) as an estimate of the number of weeks required to complete 30 assignments.
The procedure is as follows:

1. Set y = f(x)
y = 4x - 3/2

2. Exchange x and y
x = 4y - 3/2

3. Solve for y
4y = x + 3/2
y = (x +3/2)/4

4. Set y equal to f⁻¹ (x)
f⁻¹ (x) = (x + 3/2)/4

5. Find f⁻¹ (30)
f⁻¹ (30) = (30 + 3/2)/4 = 63/8 = 8 (approxmately)

Answer:
Pedro needs about 8 weeks to complete 30 assignments.
