I am having trouble with converges and diverges<br>​
inna [77]

Answer:

d. converges, -25

Step-by-step explanation:

An infinite geometric series converges if the absolute value of the common ratio is less than 1.

Here, the common ratio is 4/5:

| 4/5 | = 4/5 < 1

So the series converges.  The sum of an infinite geometric series is:

S = a₁ / (1 − r)

where a₁ is the first term and r is the common ratio.

Here, a₁ = -5 and r = 4/5:

S = -5 / (1 − 4/5)

S = -25

IRISSAK [1]

Answer:

Step-by-step explanation:

The carving was made from a scale model with a scale of 1 inch = 1 foot. This means that one foot on the actual carving is represented by one inch on the model. So the model is smaller than the actual carving.

On the model, Teddy Roosevelt's mustache was 1 foot by 8 inches long.

We would convert the 1 foot on the model to inches because the model is represented in inches

12 inches = 1 foot

This means that on the model, Teddy Roosevelt's mustache was 12 inches by 8 inches long. Therefore,

Teddy Roosevelt's mustache was 12 feets by 8 feets long on the monument or carving
