You might need:
Oduvanchick [21]

Answer:

The maximum possible number of mosquitoes is 25 millions

Step-by-step explanation:

Let

m(x) -----> the number of mosquitoes in Minneapolis, Minnesota (in millions of mosquitoes)

x ----> the rainfall in centimeters

we have

m(x)=-(x-5)^{2} +25

This is a quadratic equation (vertical parabola) open downward

The vertex is the maximum

we know that

The maximum possible number of mosquitoes is equal to the y-coordinate of the vertex

Find out the coordinate of the vertex

The general equation of a vertical parabola in vertex form is equal to

y=a(x-h)^{2} +k

where

a is a coefficient

(h,k) is the vertex

so

In this problem

a=-1 (open downward)

(h,k)=(5,25)

The y-coordinate is 25

therefore

The maximum possible number of mosquitoes is 25 millions

Which of the following is a like radical to 3 sqrt 7x?
san4es73 [151]

Answer:

Options A and B

i.e., A. 4(3\sqrt{7x}) and B. \sqrt{7x}

Step-by-step explanation:

Like radicals are similar to like terms.

For example,

x, 2x, -10x, \frac{1}{2} x, 7.3x are like terms.

xy^{2} , -9xy^{2} , 13y^{2} x are some more examples of like terms.

Similarly, like radicals are:

\sqrt{2} , -5\sqrt{2} , 1.1\sqrt{2} etc.

Hence, from the given options, like radicals to 3\sqrt{7x} are:

A. 4(3\sqrt{7x} ) and B. \sqrt{7x}
