Answer:

The expression represent the expected cost of the cell phone bill next year is: c=1.075b.

Step-by-step explanation:

With the information provided, you can say that the expected cost of the cellphone bill next year would be equal to the current bill multiplied for 1 plus the increase in decimal numbers, so the increased amount is added to the current cost. The equation would be:

c=b*(1+0.075)

c=b*1.075

c=1.075b

According to this, the answer is that the expression represent the expected cost of the cell phone bill next year is: c=1.075b.

A rectangular tank with a square​ base, an open​ top, and a volume of 8 comma 7888,788 ft cubedft3 is to be constructed of sheet
Vlad [161]

Answer:

  26 ft square by 13 ft high

Step-by-step explanation:

The tank will have minimum surface area when opposite sides have the same total area as the square bottom. That is, their height is half their width. This makes the tank half a cube. Said cube would have a volume of ...

  2·(8788 ft^3) = (26 ft)^3

The square bottom of the tank is 26 ft square, and its height is 13 ft.

_____

<em>Solution using derivatives</em>

If x is the side length of the square bottom, the height is 8788/x^2 and the area is ...

  x^2 + 4x(8788/x^2) = x^2 +35152/x

The derivative of this is zero when area is minimized:

  2x -35152/x^2 = 0

  x^3 = 17576 = 26^3 . . . . . multiply by x^2/2, add 17576

  x = 26

_____

As the attached graph shows, a graphing calculator can also provide the solution.
