The number of compact discs N purchased each year, in millions, can be
Aleonysh [2.5K]

Answer:

126.5 years

Step-by-step explanation:

N(t) = 384(1.13)^t

2,000,000,000 = 384(1.13)^t

(1.13)^t = 2,000,000,000/384

log [(1.13)^t) = log (2,000,000,000/384)

t × log 1.13 = log (2,000,000,000/384)

t = [log (2,000,000,000/384)]/(log 1.13)

t = 126.5

Find the value of z in the similar figures (round to the nearest tenth)
MrRa [10]
As they are similar figures,we can use the ratio of the side to find out the value of z.

The only side that both have the value indicated is 4 and 6,therefore we would use it to find the ratio.

The eqaution would be:
6/4 = z/8
3/2 = z/8
3×8 = 2z
z = 24/2
z = 12

Thus the value of z is 12.

Hope it helps!
