What is the distance between (-2,2) and (2,-1) on coordinate plane
lawyer [7]

Answer:

d=\sqrt(x2-x1)^{2}  + (y2-y1)^{2}

Step-by-step explanation:

1- Identify the x and  the y

x1= -2

x2=2

y1= 2

y2= -1

2-

2- solve the equation:

d=\sqrt\(2-(-2))^{2}  + ((-1)-2)^{2}

d= \sqrt(4)^{2}        + (-3)^{2}

= \sqrt16        + 9

= \sqrt25

d=5 answer

<h2>Hello!</h2>

The answer is:

The area of this figure is 946 square inches.

<h2>Why?</h2>

We can see that the figure is composed by two rectangles with diferrent dimensions, so, to calculate the area of the entire figure.

So,

For the first rectangle, we have:

Base=7in\\Height=28in

The area will be:

Area=Base*Height=7in*28in=196in^{2}

For the second rectangle, we have:

Base=25in\\Height=30in

The area will be:

Area=Base*Height=30in*25in=750in^{2}

Now, calculating the area of the entire figure, we have:

TotalArea=FirstRectangleArea+SecondRectangleArea\\\\TotalArea=196in^{2}+750in^{2}=946in^{2}

Have a nice day!

A.Calculate the mean,median and mode.(3 points each) 1.)1,2,3,4,5 2.)2,3,4,5,6,6 3.)6,7,5,4,5,6,2,5
zlopas [31]

Answer:

Step-by-step explanation:

1.)1,2,3,4,5

mean=sum of all values/number of values

         =1+2+3+4+5/5

         =15/5

mean=3

Mode :

In the given data, no observation occurs more than once.

Hence the mode of the observations does not exist, means mode=0.

Median

1,2,3,4,5

Middle value is 3 so the median is 3.

2.)2,3,4,5,6,6

mean=sum of all values/number of values

         =2+3+4+5+6+6/6

         =26/6

mean =4.33

Mode

      is that value of the observation which occurs maximum number of times so here mode is 6.

Median

2,3,4,5,6,6

 4+5/2

9/2

median=4.5

3.)6,7,5,4,5,6,2,5

mean=sum of all values/number of values

         =6+7+5+4+5+6+2+5/8

        =40/8

mean =5

Mode

is that value of the observation which occurs maximum number of times so here mode is 5

Median

2,4,5,5,5,6,6,7

5+5/2

10/2

median=5

Type the correct answer in each box. Use numerals instead of words. Consider this expression. (x+5)(x-7) Complete the box to sho
Ne4ueva [31]

In the top right corner is -7x since we multiply the x and -7

In the bottom row, we'll have 5x for the first box and -35 for the second box. Each box is the result of multiplying the outer values.

In the top left corner, the x^2 is from multiplying the two copies of x.
