Answer:

The answer is 72 meters

Step-by-step explanation:

So we know that she can walk 16 meters in 10 secs. Therefore she can walk 64 meters in 40 secs and for the 5 secs remaining you just put half of 16 which is 8. We add the 64 and 8 together and we get 72

<span>Martin deposits $200 in a savings account that earns 5% annual interest.

year         interest                     balance

1              200 * 5%                    200(1.05)

2              200(1.05) * 5%          200(1.05)^2

=> m = 200 (1.05)^y

Step-by-step explanation:

Let's find the rate of change (slope):

$let:\\(x1,y1) =(2,50)\\(x2,y2)=(4,100)\\m=\frac{100-50}{4-2} =\frac{50}{2} =25 \\$

Which of the following sets of transformation provides sufficient information to prove the two circles described are similar?

Reika [66]

<h2>Explanation:</h2><h2></h2>

A circle is simply a curve made up of all the points that are the same distance from the center. This distance is called the radius of the circle. It's important to know that <em>all circles are similar to each other</em>, but what is similarity? It's simply, shapes are similar if we can turn one into the other by moving, rotating, flipping, or scaling. So every circle can match any other circle by moving it, rotating it, flipping it, or scaling it.

Then circles O and Q shown below are similar no matter what's the radii of them.
