Answer:

principal square root

Step-by-step explanation:

Let $x^2=a$ .

Then $x=\pm\sqrt{a}$

We have a negative square root for x, which is $x=-\sqrt{a}$ and a nonnegative square root,which is $x=+\sqrt{a}$

The nonnegative square root is callled the principal square root .

Therefore the best complete to the statement;

A -------- is the nonnegative Square root of a number, is principal square root.

<h3> The missing graph is attached.</h3>

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" the y-intercept.

We can pick two points on the line graphed and substitute the coordinates into this formula to find the slope:

$m=\frac{y_2-y_1}{x_2-x_1}$

Choosing the points (0,4) and (2,10), we get:

$m=\frac{4-10}{0-2}=3$

We can susbstitute the point (0,4) and the slope into $y=mx+b$ and solve for "b":

$4=3(0)+b\\\\b=4$

Then, the equation of this line is:

$y=3x+4$

Since the distance in miles is represented on the y-axis and the time in hours is represented on the x-axis. we can rewrite the equation as:

$d=3h+4$

Finally, in order to calculate the distance in miles that the campers will be from their car after 12 hours, we need to subsitute $h=12$ into the equation and evaluate. Then we get:

$d=3(12)+4\\\\d=40$

Which function has two x-intercepts, one at (0,0) and one at (4,0)?

Tcecarenko [31]

Answer:

$f(x)=x(x-4)$

Step-by-step explanation:

Given: Function has two x-intercepts, one at (0,0) and one at (4,0)

To choose: the correct option

Solution:

x-intercepts of are the points whose x-coordinate is 0.

Consider $f(x)=x(x-4)$

Put $x=0$

$f(0)=0(0-4)=0$

Put $x=4$

$f(4)=4(4-4)=0$

So, the function $f(x)=x(x-4)$ has two x-intercepts, one at (0,0) and one at (4,0).
