Answer:
42.25 feet
Step-by-step explanation:
The height function is a parabola. The maximum value of a negative parabola is at the vertex, which can be found with:
x = -b/2a
where a and b are the coefficients in y = ax² + bx + c.
Here, we have y = -16t² + 52t. So a = -16 and b = 52. The vertex is at:
t = -52 / (2×-16)
t = 13/8
Evaluating the function:
h(13/8) = -16(13/8)² + 52(13/8)
h(13/8) = -169/4 + 169/2
h(13/8) = 169/4
h(13/8) = 42.25

Answer:
y=-1
Step-by-step explanation:
use point slope formula y-y₁=m(x-x₁)
find m which is slope -1--1/-4--1= 0/-3= 0
plug in the equation and use the first point
y--1=0(x--1)
y=-1
