puteri [66]

Answer:

9 inches of rainfall produces the maximum number of gnats.

Step-by-step explanation:

Given : $G(x) = - x^2 + 18x$

To Find :How many inches of rainfall produces the maximum number of gnats?

Solution:

$G(x) = - x^2 + 18x$

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.

$0= - x^2 + 18x$

$0= x^2-18x$

$0= x(x-18)$

So, x = 0 , x= 18

Now Formula of midpoint : $x=\frac{x_1+x_2}{2}$

$x=\frac{0+18}{2}$

$x=9$

Hence 9 inches of rainfall produces the maximum number of gnats.

irina1246 [14]

Answer:

Hello!!

If a water bottle contains 500mL of water and your goal is to drink 4L of water each day then the water bottle is $\frac{1}{8}$ of your daily goal.

Step-by-step explanation:

500mL = 0.5L

1000mL = 1L

1500mL = 1.5L

2000mL = 2L

2500mL = 2.5L

3000mL = 3L

3500mL = 3.5L

4000mL = 4L

Hope this helps!!
