1 answer:
iren [92.7K]3 years ago
3 0

Answer:

C

Step-by-step explanation:

The common ratio can be < 0

All that means is the entry's signs alternate.

For example

r = - 2

a = 3

Series = 3    -6    18     -54 etc. The members of the series become larger and larger in magnitude and the series diverges. It is not clear where it might stop.

-1 < r < 0 gives a much better behaved result.

The point is that c is incorrect.

Find the area of the right triangle. If necessary, round to the nearest tenth
Ad libitum [116K]

Answer:

B. 150 yards

Step-by-step explanation:

Area of a Triangle = .5 * Base * height

So we need the height of the triangle, or the missing side.

We have to use Pythagorean Theorem to solve this:

A^2 + B^2 = C^2

15 ^ 2 + B ^ 2 = 25 ^2

b^2 = 25^2 - 15 ^ 2

b^2 = 625 - 225

b^2 = 400

sqrt (400) = 20

The missing height is 20. Now we plug it into 1/2 * b * H

.5 * 15 * 20

7.5 * 20 = 150
