The distance between points A and B is 6 units.

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

[tex]D = √[(x-p)² + (y-q)²] D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]

We are given that;

The points= (-1.4) and B (5.-2)

Now,

To find the distance between points A (-1.4) and B (5.-2), we can use the distance formula:

d = [tex]\sqrt((x2 - x1)^2 + (y2 - y1)^2)[/tex]

where (x1, y1) and (x2, y2) are the coordinates of points A and B, respectively.

Substituting the values we have:

[tex]\sqrt{(5 - (-1))^2 + (-2 - (-4))^2}[/tex]

d = [tex]\sqrt{(5 + 1)^2 + (-2 + 2)^2}[/tex])

d = [tex]\sqrt{(6^2 + 0^2)}[/tex]

d = [tex]\sqrt{36}[/tex]

d = 6

Therefore, by the distance formula answer will be 6 units.

Step-by-step explanation: because the numbers of cars are not less nor greater than 7

The image triangle has vertices after the dilation by a scale factor of 3 are M'(0,12), N'(12,6), and P'(6,-6).

To find the image coordinates of a triangle after dilation, we need to multiply the coordinates of each point by the scale factor.

In this case, the scale factor is 3.

So the image coordinates of the triangle with vertices M(0,4), N(4,2), and P(2,-2) after dilation by a scale factor of 3 are:

M' = (3 * 0, 3 * 4) = (0, 12)

N' = (3 * 4, 3 * 2) = (12, 6)

P' = (3 * 2, 3 * (-2)) = (6, -6)

Hence, the image triangle has vertices M'(0,12), N'(12,6), and P'(6,-6).

In summary, the image coordinates of the triangle after dilation by a scale factor of 3 are M'(0,12), N'(12,6), and P'(6,-6).

In this problem we find the representation of a point and a line on Cartesian plane. There is a least distance between the point and the line when the line segment between them is perpendicular to the line. The line segment AC fulfill these features. Given the location of points A and C, we can determine the distance by means of Pythagorean theorem:

First, we need to find the number of people who went to the pool in the second, third, and fourth weeks.

Number of people in second week = 1,120 - 125 = 995

Number of people in third week = 995 + 145 = 1,140

Number of people in fourth week = 1,140 - 132 = 1,008

To find the percent decrease, we need to find the difference between the number of people in the first week and the fourth week, and then divide by the number of people in the first week.

Difference between first and fourth weeks = 1,120 - 1,008 = 112

Percent decrease = (112/1,120) x 100% = 10%

Therefore, the percent decrease in the number of people who went to the pool over these four weeks is 10%.

Using the equation, we found the following:

1) Expected Population in the year 2014 = 41100

2) Predicted year when the population will reach 54000 = 2020

3) The rate of population changes = 2150

4) The number of years for the population doubled since 2008 =9.12

What is a linear equation?

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant.

Given,

the population in 2008 = 28,200

the population in 2012 = 36,800

The population is growing linearly.

Assume a linear equation,

p(x) = 36800 + kx

where,

   p(x) = population

  x = years since 2012.

k = increase in population

p(0) = 36800

p(-4) = 36800 - 4k

28200= 36800 -4k

4k = 36800 - 28200

k = 2150

Then the linear equation becomes,

p(x) = 36800 + 2150x

1) Population in 2014

x = 2014 - 2012 = 2

From the equation,

p(2) = 36800 + 2150 * 2 = 41100

2) x when p(x) = 54000

From the equation,

54000  = 36800 + 2150x

2150x = 17200

x = 8

Year = 2012 + 8 = 2020

3) Rate of population change = (population in 2012 - population in 2008) / number of years = 36800-28200 / 4 = 2150

4) Population doubled since 2008

p(x) = 2 * 28200 = 56400

We have to find x , when p(x) = 56400

Using the linear equation,

56400 = 36800 + 2150x

x = 9.12

Therefore using the equation, we found the following:

1) Expected Population in the year 2014 = 41100

2) Predicted year when the population will reach 54000 = 2020

3) The rate of population changes = 2150

4) The number of years for the population doubled since 2008 =9.12

The centroid of the region is at the point (0, 2/5).

To find the centroid of the region bounded by the curves y=2-x² and y=x, we first need to find the limits of integration and the expressions for the x-coordinate and y-coordinate of the centroid.

The curves intersect at (1,1) and (-1,1), so we will integrate over the interval [-1,1].

To find the x-coordinate of the centroid, we need to evaluate the following integral:

x' = (1/A) ∫[a,b] xf(x) dx

where;

A = ∫[a,b] (f(x) - g(x)) dx

In this case, f(x) = 2 - x² and g(x) = x, so

A = ∫[-1,1] (2 - x² - x) dx

= [2x - (1/3)x³ - (1/2)x²] | from -1 to 1

= (4/3)

Now we can evaluate the x-coordinate of the centroid:

x' = (1/A)∫[-1,1] x*(2-x²-x) dx

= (1/(4/3))∫[-1,1] (2x - x³ - x²) dx

= (3/4) [(x²/2) - (1/4)x⁴ - (1/3)x³] | from -1 to 1

= 0

So the x-coordinate of the centroid is 0.

To find the y-coordinate of the centroid, we need to evaluate the following integral:

y' = (1/A) ∫[a,b] (1/2) [f(x)² - g(x)²] dx

y' = (1/(4/3)) ∫[-1,1] (1/2)[(2-x²)² - x²] dx

= (3/4)[(8/15)x⁵ - (2/3)x³ + (1/2)x] | from -1 to 1

= (2/5)
