The answer is d as for any given length you could have any given volume by altering the cross sectional area of the pool and vice versa
Answer:
f(x)=13x[+4. that one is the Correct answer. I hope it help.
Answer:
x = 8 is the answer :)
Step-by-step explanation:
Slope(m) = -2/5
slope is passing through the points: (x,1) and (3,3)




-2(3 - x) = 2 × 5
-6 + 2x = 10
2x = 10 + 6
2x = 16
x = 8
Hopefully, this answer helped :)
Answer:

Step-by-step explanation:
f(x) = 9x³ + 2x² - 5x + 4; g(x)=5x³ -7x + 4
Step 1. Calculate the difference between the functions
(a) Write the two functions, one above the other, in decreasing order of exponents.
ƒ(x) = 9x³ + 2x² - 5x + 4
g(x) = 5x³ - 7x + 4
(b) Create a subtraction problem using the two functions
ƒ(x) = 9x³ + 2x² - 5x + 4
-g(x) = <u>-(5x³ - 7x + 4)
</u>
ƒ(x) -g(x)=
(c). Subtract terms with the same exponent of x
ƒ(x) = 9x³ + 2x² - 5x + 4
-g(x) = <u>-(5x³ - 7x + 4)
</u>
ƒ(x) -g(x) = 4x³ + 2x² + 2x
Step 2. Factor the expression
y = 4x³ + 2x² + 2x
Factor 2x from each term
y = 2x(2x² + x + 1)
