Answer:
Lesser x is -13.
Greater x is 1.
Step-by-step explanation:
We have the function:
And we want to find the zeros of the function.
So, set f(x) to 0 and solve for x:
Add 49 to both sides:
Take the square root of both sides. Since we're taking an even root, we will need plus/minus:
Subtract 6 from both sides:
Evaluate for each case:
Case 1; 7 is positive:
Case 2; 7 is negative:
So, our zeros are:
Our lesser x is -13, and our greater x is 1.
And we're done!
Answer:
Step-by-step explanation:
Set this up as a proportion with the number of inches of rain on the top and the number of hours it rained on the bottom.
and cross multiply to solve for x:
15x = 13125 so
x = 875 inches
Answer:
8+5x=24

I'm just guessing but try -7
Answer:
9.936
Step-by-step explanation:
V = Bh
B = base
base = Lengh x width
base = 4.8 x 2.3
base = 11.04
V = 11.04h
H = height
H = .9
V = .9 x 11.04
V = 9.936
