Answer:

  they are not inverses

Step-by-step explanation:

f(1) = 1/1 +3 = 1 +3 = 4

g(4) = 4/4 +2 = 1 +2 = 3 ≠ 1

If the functions were inverses, we would have g(f(1)) = 1, which we do not.

The given functions  are not inverses.

_____

The same would be true if your functions were

  f(x) = 1/(x+3) and g(x) = 4/(x+2)

  f(1) = 1/(1+3) = 1/4

  g(1/4) = 4/(1/4 +2) = 4/(9/4) = 16/9 ≠ 1

Hyla has blocks of clay that are each 4 centimeters by 4 centimeters by 2 centimeters. She needs to cover the bottom of a box wi
LenaWriter [7]

The number of blocks of clay needed by Hyla is 30 blocks

<h3>What is area?</h3>

Area is the region bounded by a plane shape.

To calculate the number of blocks of clay needed by Hyla, we find the area of the bottom of the box and divide it by the area of the block.

Formula:

  • n = LWH/lwh............... Equation 1

Where:

  • n = Number of blocks of clay needed by Hyla
  • L = Length of the bottom of the box
  • W = Width of the bottom of the box
  • H = Height of the box
  • l = Length of the bottom of the block
  • w = Width of the block
  • h = Height of the block.

From the question,

Given:

  • L = 24 cm
  • W = 20 cm
  • H = 2 cm
  • l = 4 cm
  • w = 4 cm
  • h = 2cm

Substitute these values into equation 1

  • n = (24×20×2)/(4×4×2)
  • n = 30

Hence, The number of blocks of clay needed by Hyla is 30 blocks
