Answer:

D. 154

Step-by-step explanation:

The area of the rectangle is 15*5= 75 inches

The area of the 2 semicircles combined, which make a circle, are:

π*r², where r is 5

r²=25

π*25=78.53981633

75 + 78.53981633 is about 154

What is the equation of the line in point-slope form that has a slope of -3 and passes through the point (5, 9)?

krek1111 [17]

Answer:

$y-9=-3(x-5)$

Step-by-step explanation:

The equation of the line in point-slope form is given as

$y-y_1=m(x-x_1)$

Here m=-3 and (x1, y1)=(5, 9)

Therefore,

$y-9=-3(x-5)$

Hello from MrBillDoesMath!

Answer:

The equations "are balanced"

Discussion:

Given that

4 + 4 = 8 => subtracting k from both sides

4 + 4 - k = 8 -k

so the equation shown IS correct. The answer should be the equations "are balanced"

Thank you,

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.
