The height of the building comes to be 81 feet.
Initial velocity u= 0 feet/sec
Final velocity v= 72 feet/sec
The acceleration due to gravity g =32ft /sec²
Height of the building h= suppose h
<h3>What is the equation of motion?</h3>
The equation of a motion is:
![v^{2} =u^{2} +2gh](https://tex.z-dn.net/?f=v%5E%7B2%7D%20%3Du%5E%7B2%7D%20%2B2gh)
Where u and v are the initial and final velocities.
![72^{2} =0+2*32*h\\144 = 64h\\h=81](https://tex.z-dn.net/?f=72%5E%7B2%7D%20%3D0%2B2%2A32%2Ah%5C%5C144%20%3D%2064h%5C%5Ch%3D81)
So, the height of the building = 81 feet.
Therefore, the height of the building comes to be 81 feet.

Answer:
$62.05 for 20 gallons
Sorry if I didn't get it correct. I don't really understand how you worded your question. <3
Step-by-step explanation:
$81 for 25 gallons =
81/25 = $3.24 for 1 gallon
$62.05 for 20 gallons =
62.05 / 20 = $3.10 for 1 gallon
Answer:
4n²+2n as a factorial is given as:
![= (2n+1)!/(2n-1)!](https://tex.z-dn.net/?f=%3D%20%282n%2B1%29%21%2F%282n-1%29%21)
Step-by-step explanation:
We are given an expression which has to be converted into factorial form.
The expression is as follows:
![4n^{2} + 2n\\ = 2n(2n+1)\\ = (2n+1)2n\\](https://tex.z-dn.net/?f=4n%5E%7B2%7D%20%2B%202n%5C%5C%20%3D%202n%282n%2B1%29%5C%5C%20%3D%20%282n%2B1%292n%5C%5C)
Now we know that 2n+1 and 2n differs by '1' and the next smaller term is '2n-1'.
Hence, multiplying and dividing by '(2n-1)!'; we get:
![= ((2n+1)(2n)(2n-1)!)/(2n-1)!](https://tex.z-dn.net/?f=%3D%20%28%282n%2B1%29%282n%29%282n-1%29%21%29%2F%282n-1%29%21)
we know that x(x-1)(x-2)! = x!, so:
![= (2n+1)!/(2n-1)!](https://tex.z-dn.net/?f=%3D%20%282n%2B1%29%21%2F%282n-1%29%21)
