The infinite geometric series is converges if |r| < 1.
We have r = 0.7 < 1, therefore our infinite geometric series is converges.
The sum S of an infinite geometric series with |r| < 1 is given by the formula :
We have:
Substitute:
Answer: c. Converges, 40.
Answer:
28 bees per square feet.
Step-by-step explanation:
The radius of the circle is 3 feet.
Therefore, area of the circle is equal to square feet.
Now, in this area of 28.28 square feet, there live 800 bees.
Therefore, the population density of bees per square foot will be bees per square foot ≈ 28 bees per square feet. (Answer)
