Answer:
1312.5 cubic feet
Step-by-step explanation:
Let the swimming pool be a rectangular prism
The volume of a rectangular prism is:
Volume = length * width * depth
Length = 25 (given)
Width = 15 (given)
The depth is 4ft, but they want the volume when water is 6 inches FROM THE TOP, that is, out of 4 feet, 6 inches (1/2 feet) IS NOT FILLED. So the depth of water is
4 - 1/2 = 3.5 feet
So, we can say
Depth = 3.5 (found)
Hence, the volume would be:
Volume = 25 * 15 * 3.5 = 1312.5 cubic feet
(3s^13)(9s^-5) is simply a matter of multiplication.
First, multiply the coefficients, or the numbers in front of the s. In this case, 3s x 9s = 27s.
When multiplying exponents, you simply add them, so the next step is 13-5 or 8. Therefore your answer is 27s^8

<span>If a and h are real numbers, find the following values for the given function.
f(x) = 7 − 3x
(a)
f(a) = 7-3a
------------------------
(b)
f(−a) = 7-3(-a) = 7+3a
------------------------
(c)
−f(a) = -(7-3a) = 3a-7
------------------------
(d)
f(a + h) = 7 -3(a+h) = 7-3a-3h
------------------------
(e)
f(a) + f(h) = (7-3a)+(7-3h) = 14-3a-3h
------------------------
(f)
if h ≠ 0,
[f(a + h) − f(a)]/h = {[7-3a-3h]-[7-3a]}/h = [-3h]/h = -</span></span>
