Answer:

120 people/sq. mile

Step-by-step explanation:

Population Density is the concept of how "crowdy" a place is. The more the population density, the more crowded that place is.

The population density is found by dividing the "number of people" by the "land area" (in sq mile or sq km).

Here, it is given there are 600 million people, so

Number of People = 600,000,000

And, the land area is given as 5 million square miles, so

Land Area = 5,000,000 sq. miles

Hence,

Population Density = 600,000,000/5,000,000 = 120 people/sq. mile

What is the equation of the line in slope-intercept form? Line on a coordinate plane. The line runs through points begin ordered
Marrrta [24]

Find the equation of the line connecting (0, 5) and (-2, 0).

As we go from the first point to the second, x decreases by 2 and y decreases by 5.  Thus, the slope of this line is m = rise / run = -5/(-2), or 5/2.

Starting with the general equation of a line in slope-intercept form, y = mx + b, substitute the knowns as appropriate to determine the value of b:

y= mx + b => 5 = (5/2)(0) + b.  Then b = 5, and the desired equation is

y = (5/2)x + 5.

Check this!  If we subst. the coordinates of (-2,0) into this equation, is the equation true?

0 = (5/2)(-2) + 5

Yes.  So, y = (5/2)x + 5 is the desired equation.

I need the solution and the work for it... for each of the multiple choices.
Vlad1618 [11]

For this case we have the following equation:

x ^ 3 = 375

We must find the value of "x":

We apply cube root on both sides of the equation to eliminate the exponent:

x = \sqrt [3] {375}

We can write 375 as 5 ^ 3 * 3

So:

x = \sqrt [3] {5 ^ 3 * 3}\\x = 5 \sqrt [3] {3}

Then, the correct options are:

x = \sqrt [3] {375}\\x = 5 \sqrt [3] {3}

Answer:

Option A and B
