15 seconds at high speed
1 sec = 40 cm
15 sec = 40 x 15
15 sec = 600 cm
30 seconds at low speed
1 sec = 15 cm
30 sec = 15 x 30
30 sec = 450 cm
Total distance = 600 + 450 = 1050 cm
All cone-shaped cups have the same height in 8 inches. They just differ in their diameters. To solve for the volume of the regular and jumbo sizes, let's use the formula for the volume of cone
V = (1/3)*pi*(r^2)*h
r is just the half of the diameter, h is the height which is equal to 8
Regular size:
V = (1/3)*pi*((4/2)^2)*8
V = 33.5 cube inches
Jumbo size:
V = (1/3)*pi*((8/2)^2)*8
V = 134.0 cube inches
Answer:
maximum profit 
Step-by-step explanation:
Given that,
The company estimates that the initial cost of designing the aeroplane and setting up the factories in which to build it will be 500 million dollars.
The additional cost of manufacturing each plane can be modelled by the function.
Find the cost, demand (or price), and revenue functions.
Find the production level that maximizes profit.
Find the associated selling price of the aircraft that maximizes profit.
Find the maximum profit.
Manufacturing cost of one plane is:
maximum profit
