Tcecarenko [31]

Answer:

printer A- 36/1.5

printer B- 114/3

printer C- 115/5

first, multiply 1.5 x 10, 3 x 5, and 5 x3

you should get 15 for each.

once you have the denominators all done, multiply the numerators by the value you multiplied the denominator by and you should have your answer.

so all in all, printer B prints the fastest

if the circumference of a circle is 52 cm, what is the radius? round to the nearest tenth. PLESE HELP I DONT HAVE THAT MUCH TIME

Step2247 [10]

Answer:

8.3

Step-by-step explanation:

Given, 

Circumference of the circle = 52 cm

Therefore ,

By the problem, 

$= > 2\pi r = 52$

$= > 2 \times 3.14 \times r = 52$

$= > r = \frac{52}{3.14 \times 2}$

=> r = 8.2802547771

In 2-3 sentences describe why the only way an infinite geometric series has a sum is if |r| < 1.

alisha [4.7K]

Answer:

Step-by-step explanation:

A geometric series is one where each term is multiplied by a constant value known as r to get the next term

Sum of n terms of a geometric series is

$\frac{a(r^n-1}{r-1},|r|>1\\\frac{1-r^2}{1-r},|r|$

Sum of infinite series is obtained as the limiting value of this sum when n tends to infinity

We find that only when |r|<1, r power n tends to 0 as n tends to infinity.

Other r power n diverges.

Hence geometric series infinite sum formula is valid only when

|r|<1 since the series sum converges to a finite value
