I like area questions.

On the left we have a triangle, base apparently 9 cm, height 7 cm.

In the middle it's a 3 cm by 9 cm rectangle.

Then it's a parallelogram, base 9. We have to figure out the height; it must be 16 - 7 - 3 = 6 cm.

Adding up the areas,

A = (1/2) 9×7 + 3×9 + 6×9 = 112.5 sq cm

Answer: 112.5 sq cm

TIMED***Which equation is represented by the graph below?

Anuta_ua [19.1K]

From the graph we observe:
If x = 0 then y = 1/2 (because e⁰ = 1)

$\displaystyle \bf \\
\Longrightarrow~~\boxed{\bf y = \frac{1}{2} e^x}$

Prove that the two circles shown below are similar.

s344n2d4d5 [400]

The circles B and D are similar since the radius of the former is as twice as the radius of the latter.

<h3>Are the two circles shown in the figure similar?</h3>

By geometry we know that circles are defined by only one characteristic: radius. If two circles are similar, then the radii must be <em>different</em>. After a quick look at the figure, we conclude that the radii are $r_{B} = 4$ and $r_{D} = 2$ . Hence, the circles B and D are similar since the radius of the former is as twice as the radius of the latter.
