H = -16t^2 + 40t + 11

we need to covert this to vertex form 

h = -16(t^2 - 2.5t) + 11

   = -16 [(t - 1.25)^2 - 1.5625] + 11
  
   = -16(t-1.25)^2 + 25 + 11

= -16(t - 1.25)^2 + 36

The answer is  36 feet

What is an equation of the line that is perpendicular to y=-3/4x+6 and passes through the point (3,9)
goldenfox [79]

Answer:

y=\frac{4}{3}x+5

Step-by-step explanation:

The line y= -3/4+6 in the comments has slope -3/4. A perpendicular line will have the negative reciprocal of -3/4. It's 4/3.

To write the equation, substitute 4/3 and the point (3,9) into

y-y_1 = m(x-x_1)

y-9=\frac{4}{3}(x-3)\\\\y-9=\frac{4}{3}x -\frac{4*3}{3}\\\\y-9=\frac{4}{3}x-4\\\\y=\frac{4}{3}x+5
