If 18.9 million computers were in use in 1980 and the number is rising by 19% annually, predict the number of computers in use in 2015. round to the nearest whole number of million. subject: exponential growth and decay

8329 millions.

Step-by-step explanation:

The exponential growth equation is modeled as :

, where A is the initial amount, r is rate of increase and x is the time period.

Given: The number of computers used in 1980= 18.9 million

The rate of growth = 19% =0.19

The number of years from 1980 to 2015= 35

Now, the number of computers in use in 2015 is given by :-

Hence, the number of computers in use in 2015= 8329 millions.

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
