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

Answer:
B.62.8 inches
Step-by-step explanation:
just multiply the diameter by pi to get the circumference
20 x 3.14= 62.8
Answer:
<h2>
70cm/s</h2>
Step-by-step explanation:
Area of a square with side of length L is expressed as A = L². The rate at which the area is increasing will be expressed as dA/dt.
dA/dt = dA/dL * dL/dt where
dL/dt is the rate at which each side of the square is increasing.
Since dA/dL = 2L, dA/dt = 2L dL/dt
Given dL/dt = 5cm/s and the Area of the square = 49 cm²
49 = L²
L = √49
L = 7cm
dA/dt = 2(7) * 5
dA/dt = 14*5
dA/dt = 70cm/s
The rate at which the area of the square is increasing is 70cm/s
B sometimes
A rhombus MUST have 4 equal sides, but like a parallelogram,it can have matching pairs of angles that are supplementary
