Answer:an=9⋅(2/3)^n−1






irga5000 [103]3 years ago

Answer:

The answer is an= 2/3 * 9^n-1

or D

Step-by-step explanation:

The explicit rule is an=a1 * r^n-1

the question tells us that a1 is 2/3, so we plug that into the rule

the question uses the recursive rule ( an=r * an-1) to tell us what r is

r= 9 and a1= 2/3

now lets plug it into our rule

an= 2/3 * 9^n-1

4 2/3 divide by 1 2/3
sladkih [1.3K]

Answer:

14/5

Step-by-step explanation:

I'd suggest rewriting both mixed numbers as improper fractions.  Then we'd have:

14/3 and 5/3

Dividing 14/3 by 5/3 is equivalent to dividing 14 by 5, since the denominators are the same (3).

Quotient is 14/5.

Need help on this question too hard :((​
andrew-mc [135]

Answer:

2/3

Step-by-step explanation:

Convert the fractions to decimals.

2/3 = 0.666

4/5 = 0.8

14/18 = 0.777

34/50 = 0.68

From the decimals, 0.666 is the only option which falls between 0.5 and 0.75.
