Find the three positive geometric means between 3 and 48/625

A. 9/5, 27/25, 81/125

B. 6/5, 12/25, 24/125

C. 3/5, 3/25, 3/125

D. 1, 1/3, 1/9

Step-by-step explanation:

Let the geometric means to be inserted be x, y and z. The geometric series will contain 5 terms as shown:

3, x, y, z, 48/625

Using the nth term of a geometric sequence to find the missing term.

where:

a is the first term

n is the number of terms and

r is the common ratio

From the sequence, a = 3

Since the fifth term is 48/625 then:

To get the 2nd, 3rd and 4th term, we will substitute the value of the first term and the common ratio in the equation given.

when n = 3;

when n = 4;

The three positive geometric mean are 6/5, 12/25, 24/125

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
