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:
D. The function f has 3 horizontal tangent lines
Step-by-step explanation:
Well whenever any function crosses the x-axis, it means that the y-value is equal to zero.
In this case when the derivative passes the x-axis it indicates the tangent line corresponding to that x-value has a slope of zero, which when plotted is a horizontal line.
This means that the graph f has 3 horizontal tangent lines.
Answer:
Step-by-step explanation:
Sum of the angles of a triangle is ALWAYS 180°.
2x+3x+5x = 180°
10x = 180°
x = 18°
2x = 36°
3x = 54°
5x = 90°
The angles are 36°, 54°, and 90°
You should do 1.0 divided by 7 and the answer would be 7
12.5 is your answer! Hope I helped! :D
