Answer:
9 inches of rainfall produces the maximum number of gnats.
Step-by-step explanation:
Given : 
To Find :How many inches of rainfall produces the maximum number of gnats?
Solution:
G(x) =The number of gnats in millions.
x denotes the length of rainfall
To Find the maximum length find the mid point of zeroes .Since parabolas are symmetrical, the x value of the max falls 1/2 way between the zeros.
So, x = 0 , x= 18
Now Formula of midpoint : 
Hence 9 inches of rainfall produces the maximum number of gnats.
Answer:
8/27 is represented in decimal as 0.2962962963
3n + (4n - 2) = 15
is how this equation would be displayed.
Now let's solve for x.
We can distribute a 1 to each term in the parentheses (which doesn't do much) to allow us to combine like terms.
3n + 4n - 2 = 15
Combine like terms.
7n - 2 = 15
Add 2 to both sides.
7n = 17
Divide both sides by 7.
n = 17/7
Answer:
g = ±2h
Step-by-step explanation:
4g^2 -1= 16h^2 -1
Add 1 to each side
4g^2 -1+1= 16h^2 -1+1
4g^2 = 16h^2
Divide each side by 4
4/4g^2 = 16/4h^2
g^2 = 4 h^2
Take the square root of each side
sqrt(g^2) = ±sqrt(4h^2)
g = ±sqrt(4h^2)
g = ±2h
Answer:
1.56
