Step-by-step explanation:
Step-by-step explanation:
commision = 7% of $9000
commision = 7/100 * $9000
commision = $630
The answer will be narrow
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
784.5+(784.5×0.065)
=784.5+50.9925==835.4925 round the answer=835.5
