Answer 1

Answer:

Explicit rule formula: a(n) = a · rⁿ⁻¹

a(n) = ⁿth term

a = first term

r = common ratio

ⁿ⁻¹ = the previous term

In the recursive rule a₁ = 2/3; aₙ = 9 · aₙ₋₁ the first term is 2/3 and the common ration is 9. We can fill in the explicit formula with what we know.

Thus, the correct answer is [ aₙ = 2/3 · 9ⁿ⁻¹ ]

Best of Luck!

Answer 2

Answer:

Answer:

$a_(n) =(2)/(3)*9^(n-1)$

Step-by-step explanation:

a1 = 2/3

an = 9*a(n-1)

a2 = 9 *a1 = 9* 2/3

a3 =9*a2 = 9 *(9*2/3) = 9²*2/3

a4 = 9*a3 = 9* (9²*2/3) = 9³*2/3

PLEASE HELP!!! I WILL UPVOTE-MEDAL U!!The following graph shows the amount of water remaining in a ten-liter water jug t minutes after it started leaking. How many minutes did it take until the ten-liter jug was half empty?

Graph with t in minutes on the x axis and liters of water left in jug on y axis. Line hitting (0, 10), (4, 8), (8, 6), (12, 4), (16, 2), and (20, 0)

4 minutes

10 minutes

12 minutes

20 minutes

Answers

It is B 10 minutes. Because every 4 min 2 litters leaked out since half of 10 litters is 5 liters and 5 divide by 2 is 2.5 then 4 time 2.5 is 10 so 10 min.

How do you work this problem? 5+1/7b=-2

Answers

b= -49
5+1/7b=-2
1/7b=-2-5
1/7b=-7
B= -7 divied by 1/7
B= -7 x 7/1
B= -7 x 7
B= -49

b=-7x7 = b=49
so 7 times 7 equals 49
