4 0

Answer:

<h3>The mistake that Chelsea made was that she instead of adding 5 to both sides at step 4, she subtracted them. If she added the 5 instead of subtracting it, the answer she should've gotten was -2.</h3>

A circular sign is precisely designed to have an area of 50.24 square inches. What is the sign's circumference?
choli [55]

Step-by-step explanation:

First of all we need to know the formula for the circumference which is: c=2\pi r

We don't have the radius. What we only have is the area; therefore, we must use the area formula and extract the radius from it.

The formula for the area is: A=\pi r^2 Solve for r;

r^2=\frac{A}{\pi}\\ r=\sqrt[]{\frac{A}{\pi} }

r=\sqrt[]{\frac{50.24inch^2}{3.14} }

r=\sqrt[]{16inch^2}\\ r=4inch

Now that we've found the radius, we simply plug it into the circumference formula.

C=2\pi r\\C=2(3.14)(4)\\C=25.12inch

Polygon ABCD is defined by the points A(-4,2) B(-2, 4), C(1, 3) &amp; D(2,2). Match the coordinates of the points of the transfo
dalvyx [7]

Answer:

D'(-2, 2); C''(3, -1); A'''(4, -2); and B''(4, 2)

Step-by-step explanation:

See attachment for the figure.

<u>For D'</u>, rotating the point (2, 2) 90° counterclockwise. This maps each point (x, y)→(-y, x); it takes (2, 2)→(-2, 2).  

For C'', rotating the point (1, 3) 90° clockwise.  This maps each point (x, y)→(y, -x); it takes (1, 3)→(3, -1).

For A''', rotating the point (-4, 2) 180° clockwise.  This maps every point (x, y)→(-x, -y); it takes (-4, 2)→(4, -2).

For B'', rotating the point (-2, 4) 270° counterclockwise.  This is the similar as rotating the point 90° clockwise.  This maps every point (x, y)→(y, -x); it takes (-2, 4)→(4, 2).
