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
Domain: all x values between the ends of a line on the x- axis
Range: all y values between the ends of a line on the y-axis
Answer:
The answer is B.
Step-by-step explanation:
Solve for x.
-5x + 5 
160 - 10x
Add 10x to both sides, and subtract 5 from both sides.
5x 155
Now, divide by 5.
x 31 is the answer
