A small refrigerator is a cube with a side length of 12 inches use the formula S= 6s2 to find the surface area of the cube

Luda [366]

Answer:

Surface area of the refrigerator is 864 in².

Step-by-step explanation:

Formula to calculate the surface area of a cube is,

Surface area = 6s²

Here, s = length of a side of the cube

If side length 's' = 12 inches

By substituting this value in the formula,

Surface area = 6(12)²

= 6 × 144

= 864 inch²

Therefore, surface area of the refrigerator is 864 in².

A linear revenue function is R = 12x. (Assume R is measured in dollars.) what is the slope? What is the revenue received from se

kherson [118]

Answer:

12 ; 12 dollars

Step-by-step explanation:

Data provided in the question:

Revenue function, R = 12x

R is in dollars

Now,

The slope can be found out by differentiating the above revenue function w.r.t 'x'

thus,

$\frac{\textup{dR}}{\textup{dx}}$ = $\frac{\textup{d(12x)}}{\textup{dx}}$

slope = 12

Now, for the second case of selling one more unit i.e x = 1, the revenue can be obtained by substituting x = 1 in revenue function

therefore,

R = 12 × 1 = 12 dollars
