Answer:

Step-by-step explanation:

A series is said to be convergent if |r| < 1. Where r is the common ratio of the series.

If |r| ≥ 1 then the geometric series diverges.

-5 + 25 - 125 + ..

r = -5/25 = -1/5

r = 25/-125 = -1/5

|r| = 1/5

In the series is |r| less than 1. So the series is convergent.

If r=10 and s=31, find R. Round to the nearest tenth.

Answer:

C. R = 17.9 degrees

Step-by-step explanation:

We have a rectangle triangle with the adjacent side and the opposite side (neither of which are the hypotenuse).

The relation between those elements is the tangent:

$tan(angle) = \frac{Opposite side}{Adjacent side}$

So, to isolate the angle, we modify the formula as such:

$angle = arctan(\frac{Opposite side}{Adjacent side}) = arctan(\frac{10}{31}) = arctan(0.3225) = 17.87$

If we round 17.87 degrees to the tenth... we get 17.9 degrees.
