Have a great day!
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 = 4
Step-by-Step explanation:
4x5 = 20
2x5 = 10
20+10=30.
(4x5) + (2x5) = 30
or
(yx5) + (2x5) = 30
Brainliest would be appriciated :) have a nice day!
