Answer:
- The lowest point = 20 ft
- The highest point = 60 ft
- The diameter of the wheel = 40 ft
Step-by-step explanation:
<h3>Given</h3>
- The radius = 20 ft
- Distance from the ground to the center = 40 ft
<h3>To find</h3>
- The lowest point
- The highest point
- The diameter of the wheel
<h3>Solution</h3>
- The diameter = 2*radius = 2*20 ft = 40 ft
- The lowest point = distance to the center - radius = 40 ft - 20 ft = 20 ft
- The highest point = the lowest point + diameter = 20 ft + 40 ft = 60 ft

Step-by-step explanation:
Answer:
(A) 100 (in thousands)
(B) 180 (in thousand dollars)
Step-by-step explanation:
Given:
profit function as P(q) = -0.02q² + 4q - 20
where,
q is the number of thousands of pairs of sunglasses sold and produced,
P(q) is the total profit in thousands of dollars
To find the point of maxima differentiating the above equation and equating it to zero
P'(q) = - (2)0.02q + 4 - 0 = 0
or
⇒ - 0.04q + 4 = 0
or
⇒ - 0.04q = - 4
or
⇒ q = 100
Hence,
(A) 100 pairs of sunglasses (in thousands) should be sold to maximize profits
(B) Substituting the value of q in the profit function to calculate the actual maximum profit
P(q) = -0.02(100)² + 4(100) - 20
or
P(q) = - 0.02(10000) + 400 - 20
or
P(q) = - 0.02(10000) + 400 - 20
or
P(q) = 180 (in thousands dollar)
