Answer:

21. An= 100 (2)^n-1

22. $51,200

23. n= 15

Step-by-step explanation:

21. 100, 200, 400, 800, 1600...

An= A r ^n-1

22. a10= 100(2)^10-1

a10= 100(2)^9

23. n=14

a14= 100(2)^14-1= 819200

n= 15

a15= 100(2)^15-1= 1638400

this is about similar triangles :)which of the following statements is true about similar triangles?the measurements of correspo

GenaCL600 [577]

Similar triangles:

Similar triangles have two important properties:

1. The corresponding sides of the triangles are proportional.

2. The corresponding angles of the triangles are congruent.

Let us analyze each of the given options.

1. The measurements of corresponding angles differ between the two triangles.

False, since the corresponding angles must be congruent.

2. Two triangles are similar if their corresponding sides are proportional.

True, since the corresponding sides are proportional in similar triangles.

3. If two triangles are similar, both their corresponding sides and angles are always congruent.

False, since only the angles need to be always congruent not the sides.

4. Similar triangles differ in shape but are the same in size.

False, since similar triangles are the same shape, but not necessarily the same size.

Find the sum +5+(-2)

Nana76 [90]

Answer: +3

Step-by-step explanation: The answer is positive 3 because if you look on a number line, you will only move 3 spaces to the right. You could also look as this problem as a subtraction problem. 5-2=3. Tip: While adding positive and negative numbers, look at the bigger number in the problem. In this case it's 5. The five is positive so the answer is positive. If the five were to be negative, the answer would be negative. In adding the larger number dictates whether the sum will be positive or negative.
