Answer:
what do you have to do this?
Step-by-step explanation:
what grade and type of math is this?
The answer would be 5.291 10 to the power of 12
V = 1/3Bh
B = 1/2(b1 + b2)t
V = 1/3[1/2(b1 + b2)t] * h
h = 24
b1 = 13
b2 = 29
t = ?
V = 2856
Substitute:
2856 = 1/3[1/2(13 + 29)t](24)
2856 = 1/6(42)(24)t
2856 = 7(24)t
2856 = 168t
t = 2856/168 = 17 in height of the trapeziod
The number of seconds it takes for the waste to hit the ground for the given function is: 5 seconds.
<h3>How to Evaluate a Function?</h3>
We are given the function of height to time as, h(t) = -16t² + initial height, and we have the following:
- h(t) = 0 (height of the ground is 0)
- t = seconds the waste takes to height the ground
- Initial height = 400 feet
Plug in the values into the equation of the function
0 = -16t² + 400
Solve for t
0 - 400 = -16t²
-400 = -16t²
-400/-16 = t²
400/16 = t²
√(400/16) = t
20/4 = t
5 = t
t = 5
The number of seconds it takes is: 5 seconds.

The rate of ascent is also known as the slope. To find the slope, we will follow the steps below.
Step 1) Choose two points on the line
Point 1: (4, 500)
Point 2: (8, 1000)
Step 2) Use the slope formula to find the slope
m = (y2 - y1) / (x2 - x1)
m = (1000 - 500) / (8 - 4)
m = 500 / 4
m = 125 feet per minute
Hope this helps! :)
