Answer:
x = 17.9
Step-by-step explanation:
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
Answer:
x=58 degrees
Step-by-step explanation:
The angle DB is equal to 90 degrees, so if you subtract 32 from 90 you get x, which is 58.
Add the exponents if the bases are the same, multiply the bases if the exponents are the same, if nothing is the same just solve it.
The line is parallel to y axis
We know that if a line is parallel to y axis
So there is no slope
Here it has constant x value as -2
So the equation is
Option A
