And how we got the negative is because
-20 is the bigger number
So the amount of negatives took over the amount of positives
You got this:)

Examine the diagram and information to answer the question. Square ABCD has vertices at A(−2,1), B(2,7), C(8,3), and D(4,−3). Ho

BigorU [14]

Answer:

Option (1)

Step-by-step explanation:

Coordinates of the vertices are A(-2, 1), B(2, 7), C(8, 3) and D(4, -3)

Since ABCD is a square,

Perimeter of a square = 4 × (length of a side)

= 4 × (AB)

Formula to calculate the distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is,

d = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Therefore, distance between two points A(-2, 1) and B(2, 7) will be,

AB = $\sqrt{(2+2)^2+(7-1)^2}$

AB = $\sqrt{4^2+6^2}$

AB = $\sqrt{52}$

AB = $2\sqrt{13}$

Now area of square ABCD = 4 × $2\sqrt{13}$

= $8\sqrt{13}$ unit

Therefore, option (1) will be the answer.

Average rate of change

Ganezh [65]

Answer:

The average rate of change in that space would be 12.

Step-by-step explanation:

To find this, use the two ordered pairs (-1, 3) and (1, 27) in the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (27 - 3)/(1 - -1)

m = 24/2

m = 12

170 percent converted to a fraction equals: ...?

Verdich [7]

There are several ways to do this by converting the percentage to a fraction by placing thee expression over 100100. Percentage means out of 100 and it will look like this 170/100.
Reduced the expression. 17/10
or in whole number it is 1 17/10
