The correct answer is B. Pie chart

Explanation:

A graph refers to a diagram or image used to represent information, especially numerical data through lines, bars, among others depending on the type of graph. In the case of pie charts, these graphs include a circle that represents the100% of some variables, for example, students in a school, and that is divided into portions to represent specific data, for example, students that like volleyball, soccer, baseball, etc. This graph differs from others because most graphics include two axes, but pie charts only include a circle and portions on it representing data.

The number of gnats G(x), in millions, in a certain area depends on the May rainfall x, in inches. That relationship can be expr

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.
