Answer:

Step-by-step explanation:

47- (2 x 4) first multiply what's in the parentheses

47 - 8 next subtract

39 then you have your answer

47 = 39 after you get your answer you check your work

47 = 39 + 8 you just add the number you subtracted

47 = 47 if the numbers match you know you got it right

Hope this helps

The length of the arc intercepted by a congruent central angle is proportional to the _______ in similar circles.

faltersainse [42]

Please find the attachment for a better understanding of the answer.

As we can clearly see from the diagram, as the radius of the circle reduces so does the length of the arc for the same congruent angle subtended at the center.

Thus the length of the arc intercepted by a congruent central angle is proportional to the radius in similar circles.

This can be mathematically proven as thus:

Let $l$ be the length of the arc

Let theta be the central angle

Let r be the radius.

We know that $l$ =(theta)r

Therefore, for a constant theta, the arc length will vary in the same proportion as the radius.

Determine whether the polygons are similar. If so, identify the correct similarity ratio and the similarity statement. HELP ASAP

Vilka [71]

Answer:

No, the triangles are not similar

Step-by-step explanation:

The (reduced) side length ratios, shortest to longest, are ...

12 : 18 : 20 = 6 : 9 : 10

and

5 : 12 : 13

These are not the same, so the triangles are not similar.

Find the distance between the two points in simplest radical form.

sweet-ann [11.9K]

Answer:

3 $\sqrt{13}$

Step-by-step explanation:

Calculate the distance using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = (- 9, 8) and (x₂, y₂ ) = (- 3, - 1)

d = $\sqrt{(-3-(-9))^2+(-1-8)^2}$

= $\sqrt{(-3+9)^2+(-9)^2}$

= $\sqrt{6^2+81}$

= $\sqrt{36+81}$

= $\sqrt{117}$

= $\sqrt{9(13)}$

= $\sqrt{9}$ × $\sqrt{13}$

= 3 $\sqrt{13}$
