Answer:

9.76 years turns 900 dollars into 1200 dollars.

Step-by-step explanation:

A(t) = 900*(1.03)^t

1200 = 900 * (1.03)^t Divide by 900

1200/900 = (1.03)^t

1.333 = 1.03^t Take the log of both sides.

log(1.3333) = t * log(1.03)
log 1.3333 = .1249
log 1.03 = .0128

1.249 = 0.0128*t

1.249/0.0128 t = 9.76 years.

A number divided by eleven.

Sliva [168]

Answer:

Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.
