Annette throws a ball upward. If this graph describes the trajectory of the ball, what is it’s corresponding function?

A. f(x)=x^2-6x+25
B. f(x)=-1.89x^2+11.33x+30
C. f(x)=1.89x^2-11.33x+4
D. f(x)=-x^2+6x+4
E. f(x)=x^2+6x+17

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
