Calculate the cost of manufacturing a standard cereal box if cardboard costs $0.05 per square inch.

1 answer:

7 0

The volume of the box in this problem doesn't really matter, considering that a cereal box is hollow. Assuming the surface area is 174 inches², then you can simply multiply 0.05 x 174, which is 8.7. Then put that number in the form of money to get $8.70. (seems a bit pricey for one cereal box to me ;P)

F(x)=2x-4. F(x)=2x-4 f-1x=_x+_. Complete the inverse function

natita [175]

Answer:

$f^{-1}(x) = \frac{1}{2}(x +4)$

Step-by-step explanation:

Given

$f(x) = 2x - 4$

Required

Determine the inverse function

Start by replacing f(x) with y

$y = 2x - 4$

Swap the positions of y and x

$x = 2y - 4$

Make y the subject: Add 4 to both sides

$x+4 = 2y - 4+4$

$x+4 = 2y$

Make y the subject: Divide through by 2

$\frac{1}{2}(x + 4) = y$

$y = \frac{1}{2}(x + 4)$

Replace y with f-1(x)

$f^{-1}(x) = \frac{1}{2}(x +4)$

I count five 'k's there, so that part of the expression is

k⁵ .

Two 'n's form the rest of it, so that part is n² .

The parts are multiplied, so the simplest form of the expression is

k⁵ n² .
