Answer:
The maximum volume of the box is:
Step-by-step explanation:
Given
Required
The maximum volume of the box
Let
The surface area of the box is:
So, we have:
Divide both sides by 2
Make b the subject
The volume of the box is:
Substitute:
Spit
Differentiate V with respect to a
Set to calculate a
Collect like terms
Multiply both sides by 2
Solve for a
Recall that:
Apply law of indices
So:

Answer:
$(8967/n + 8.4)
Step-by-step explanation:
0.4nx + 0.6n(x+21) = 8967
nx + 12.6n = 8967
x = 8967/n - 12.6
x+21 = 8967/n + 8.4
Where n is the no. of balls
Example: if total balls were 300
n = 300
More expensive one would cost:
8967/300 + 8.4 = $38.29
Answer:
60.6°
Step-by-step explanation:
Using trigonometry :
Opposite = Height of shadow = 42 feets
Adjacent = height of flagpole = 23.7 feets
Tan θ = opposite / Adjacent
Tan θ = height of shadow / height of flagpole
Tan θ = 42 / 23.7
Tan θ = 1.7721518
θ = tan^-1(1.7721518)
θ = 60.56
θ = 60.6°
