4. The drop that riders experience on Dr. Doom's Free Fall can be modeled by the quadratic function, h(t) = -9.8t2 - 5t + 39 where h is height in meters and t is time in seconds.
Part A: What is the starting height of riders?
Part B: According to the function, when will the height of the riders equal 0?
Part C: Will the height ever actually equal O? Why or why not?

hi

step-by-step explanation:

step-by-step explanation:

b is the correct answer

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
