part a
which storage locker is bigger? use the drop-down menus to show and explain your answer.

locker is bigger. locker a has a volume of cubic feet, which is than the volume of locker b.

part b
the monthly rent for locker a is $0.35 per cubic foot. the monthly rent for locker b is $0.40 per cubic foot. how much does it cost to rent the largest locker each month? enter your answer in the box.

$

Part A:

Locker A is bigger

Locker A has a volume 324 of cubic feet

Part B:

$113.4 each month

Step-by-step explanation:

∵ The dimensions of locker A are 6 , 6 , 9 feet

∴ Its volume = 6 × 6 × 9 = 324 feet³

∵ The volume of locker B is 306 feet³

∴ Locker A is bigger

Part B:

∵ The monthly rent for locker A = $0.35

∴ The cost of rent of the largest = 0.35 × 324 = $113.4 each month

(3x-8) or (3x+8)

step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
