Which infinite geometric series can you NOT find the sum?

Mathematics
1 answer:
Oksanka [162]2 years ago
4 0

Answer: C) 127, 152.4, 182.88, 219.456,...

Step-by-step explanation:

You can only find the sum of an infinite geometric sequence if it converges.

One criterion to see if the series converges is if:

aₙ < aₙ₋₁

This means that, as n increases, the value of the terms decreases.

This means that as n tends to infinity, aₙ tends to zero.

Then we only can find the sum of those series where the terms are decreasing.

in A, B and D the terms are decreasing, then we can find the sum of those 3 series.

Now in the case of C, the terms are increasing, then we can not find the sum of that series.

Rosa is picking out fabric for her bedroom. She has 6 fabric samples, and 2 of them are floral. What is the probability that a r
Vlada [557]

Answer:

Probability of selected sample is floral = 1 / 3

Step-by-step explanation:

Given:

Number of fabric sample = 6 sample

Number of floral sample from all samples = 2 samples

Find:

Probability of selected sample is floral

Computation:

Probability of a sample = Favorable outcome / Total outcomes

Probability of selected sample is floral = Number of floral sample / Number of fabric sample

Probability of selected sample is floral = 2 / 6

Probability of selected sample is floral = 1 / 3

Need #47 and #48 asap!!<br> 20 pts!!
sergey [27]

Answer:

47-Step-by-step explanation:

X=121 because they are vertical angles

48- first divide 96 by 6 together the surface area of each side which is equal 16 then to find the length and the width find the square root of 16 which is 4 because it is a cube the length/width/height are all equal to four. So do 4 x 4 x 4 to find the volume of one cube. Which is equal to 64 then multiple by 8 to get the total volume 512cm^3

How to write the inverse of 3x+4y=12 in f^-1 (x)?
mojhsa [17]
3x+4y=12

4y=12-3x

y=(12-3x)/4   <---------- This is f(x)

---------------------

3x+4y=12

3x=12-4y

x=(12-4y)/3

Therefore:

f⁻¹(x)=(12-4x)/3

=[4(3-x)]/3

HEYYYY GUYYYSSS HELPP MEEE, ILL MARK YOU BRAINIEST. PLEEEAAASEEEE
pentagon [3]

Answer:

C = 100 + 40n

The independent variable is n (number of months) and the dependent variable is C ( total cost)

Step-by-step explanation:

Let the total cost of the fitness center = C

Given fixed cost = $100

given cost per month = $40

let number of month = n

The total cost of the fitness center in a given 'n' month is calculated as;

C = 100 + 40n

From the above equation;

the independent variable is n (number of months) and

the dependent variable is C ( total cost)
