Answer:
32768x^5
Step-by-step explanation:
It should be 12×18. 1:3 means you take where it's at, at 1 and multiply it's size by 3.
Plug in 1 for n and solve, then plug in 2, and so on until you get to 3(6)-1=17
Answer:
(a) 8.15
(b) 12.92
Step-by-step explanation:
Given: P = $3000, r = 0.085

Where
A is the Amount
P is the Principal
r is the rate
t is the time
(a) For the amount to double, A = 2 × P
A = 2 × $3000
A = $6000



Take
of both sides

But 
∴ 


t = 8.15
(b) For the amount to double, A = 3 × P
A = 3 × $3000
A = $9000



Take
of both sides

But 
∴ 


t = 12.92
