Lena [83]

Answer: A. 87 feet


Step-by-step explanation:

1. You can find the t value of the vertex of the parabola as following:

t=-\frac{b}{2a}

2. Substitute values:

a=-16

b=70

Then:

 t=-\frac{70}{2(-16}

t=2.18

3. Substitute the vaue obtained into the equation given in the problem. Therefore, you obtain the following result:

h=-16t^{2}+70t+10\\h=-16(2.18)^{2}+70(2.18)+10\\h=86.56

4. To the nearest foot:

h=87 feet
