What common ratio would cause a geometric series to converge

Mathematics
1 answer:
iVinArrow [24]2 years ago
6 0

Answer:0

Step-by-step explanation:

The sum of a convergent geometric series can be calculated with the formula a ⁄ 1 – r, where “a” is the first term in the series and “r” is the number getting raised to a power. A geometric series converges if the r-value (i.e. the number getting raised to a power) is between -1 and 1. So the answer is 0

If f(x) equals 3X -2 what is f(5.9)
Ivanshal [37]

Answer:

f(5.9)= 15.7

Step-by-step explanation:

f(x) = 3x -2

f(5.9) = 3(5.9) -2

f(5.9) = 17.7 -2

f(5.9) = 15.7

Word Explination

If the (x) in f(x) is replaced by another variable (in this case, a number) any other x seen in the equation is replaced by that variable. For this question, the x in f(x) is replaced by 5.9. And so any other x in this equation needs to be replaced by 5.9 as well. From there on out, you solve.

Find the probability of drawing two diamonds in a row from a standard deck of 52 cards. After the first card is drawn it is set
Rina8888 [55]

Answer: 1/17

Step-by-step explanation:

First and foremost, we should note that there are 13 diamonds in a standard deck of 52 cards.

If the first card is drawn, the probability of picking a diamond is 13/52. Since it's not replaced, when another one is picked, the probability that it will be diamond will be 12/51.

We then multiply both together. This will be:

= 13/52 × 12/51

= 1/4 × 4/17

= 1/17

Roberto got $30 for his birthday. He decides to save that
shutvik [7]

After 10 weeks, the boys will have same amount in savings.

Step-by-step explanation:

Given,

Roberto already have $30.

Amount saved each week = $5

Let,

x be the number of weeks.

R(x) = 30+5x

Amount saved by Jack each week = $8

J(x) = 8x

For same amount, the functions will be equal.

R(x) = J(x)

30+5x=8x\\30=8x-5x\\30=3x\\3x=30

Dividing both sides by 3

\frac{3x}{3}=\frac{30}{3}\\x=10

After 10 weeks, the boys will have same amount in savings.
