Answer:

40 inches

Step-by-step explanation:

To find the area of a trapezoid, you have to multiply the longest base (10 inches in this case) by the highth (i can't spell lol) (the highth is 4 inches in this case). So, A= Bh Area=10*4 Area =40 inches.

Are these polygons similar ? Explain why or why not.

Answer:

Yes, the polygons are similar.

Step-by-step explanation:

A similar polygon is a polygon that shares the same scale factor as another polygon. A scale factor is a number you can multiply each side by to get a similar figure,

Step 1:

Divide a few of the sides. You do not need to divide every side to find the ratio, but do at least 2 or 3 to guarantee that the scale factor remains the same throughout the sides. Let’s divide a few pairs of sides.

$27/18=1.5$

$30/20=1.5$

$21/14=1.5$

Step 2:

To really be safe, even though we can clearly tell this is a similar figure, is we can multiply each side on the right figure by 1.5, our scale factor, and see if we generate the sides on the left figure.

$18*1.5=27$

$20*1.5=30$

$14*1.5=21$

And this is why the polygons are similar :)

Which best describes the range of the function f(x)=2/3(6)^x after it's been reflected over the x-axis

Norma-Jean [14]

The function $6^x$ is an exponential with base greater than 1. So, its range is $(0,\infty)$ , with 0 being the horizontal asymptote as $x \to -\infty$ .
