Looking at the figure, the rectangle has the vertexes (2,1), (3,-3), (-5,-5) and (-6,-1). The parallelogram has the vertexes (2,7), (3,3), (3,-3), and (2,1).

The area of a parallelogram is base times height. We have 2 vertical lines at x=2 and x=3, so the height is 1. And the length of the line from (3,3) to (3,-3) is 6, so the base is 6. Therefore the area of the parallelogram is 1*6 = 6.

The rectangle is a tad trickier since it's not aligned with either the x or y axis. But we can use the Pythagorean theorem to get the lengths.

L = sqrt((2 - -6)^2 + (1 - -1)^2)

L = sqrt(8^2 + 2^2)

L = sqrt(64 + 4)

L = sqrt(68) = 2*sqrt(17)

W = sqrt((2-3)^2 + (1- -3)^2)

W = sqrt((-1)^2 + 4^2)

W = sqrt(1 + 16)

W = sqrt(17)

And the area is length * width, so:

2*sqrt(17)*sqrt(17) = 2 * 17 = 34

And the total area is the sum of the areas, so

34 + 6 = 40

So the area of the figure is 40 square units.

Rate of change from X = 15 to X = 19.

vova2212 [387]

Answer:

26%

Step-by-step explanation:

Subtract the old amt from the new amt, then divide by the old amt:

19-15/15 = 4/15 = 26.6%. Rounded to the nearest tenth it would be 26%.

Determine the rate of change of the following linear equation as it translates from (-5, -1) to any other point on the line.

anzhelika [568]

The rate of change of the linear equation is $-\frac{2}{3}$

Explanation:

The given two coordinates are $(-5,-1)$ and $(1,-5)$

To determine the rate of change, let us use the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting the coordinates in the equation, we get,

$m=\frac{-5+1}{1+5}$

Simplifying, we have,

$m=\frac{-4}{6}$

Dividing, we get,

$m=-\frac{2}{3}$

Thus, the rate of change of the linear equation is $-\frac{2}{3}$
