Mark brainliest if you think i helped! Would really appreciate!
48x0.2= $9.6
$48-9.6=$38.40 Her friend is incorrect.
40/48 =0.83 or about 83% So, in this case she only got 17% off. :)

Answer:
-1/4x² + 3
Step-by-step explanation:
Given that:
Path of sprinkler is modeled by the quadratic function :
w(x) = -1/4(x^2 -12 )
w(x) = height of the water, in meters, at position x
The height of ceiling as a constant or Coefficient = w(x)
Expanding w(x)
-1/4(x^2 -12 )
-1/4 * x² + 1/4 * 12
-1/4x² + 3
The height of ceiling is -1/4x² + 3
8-9n=15 I believe
At least I hope
