Answer:

A = 20.25π sq meters

Step-by-step explanation:

C = 2πr

9π = 2πr

divide π from each side to get:

9 = 2r

r = 9/2 or 4 1/2

A = πr²

A = π (4.5²)

A = 20.25π

<h3>f(x) = -3·2^(x-1) -1</h3>
  • reflection across the x-axis (multiplication by -1)
  • vertical expansion by a factor of 3 (multiplication by 3)
  • shift to the right 1 unit (replace x with x-1)
  • shift down 1 unit (add -1 to the function value)

_____

<h3>f(x) = -1/4·2^(x+1) -1</h3>

You may notice this is the same as the previous question, but with the vertical expansion factor 1/4 instead of 3, and the horizontal shift left instead of right.

  • reflection across the x-axis (multiplication by -1)
  • vertical compression by a factor of 4 (multiplication by 1/4)
  • shift to the left 1 unit (replace x with x+1)
  • shift down 1 unit (add -1 to the function value)
