The number of subscribers to a streaming video service doubles each week.
the function f(x) = 2* represents the number of subscribers in week x. when
are there 64 subscribers?

a. week 6
b. week 32
c. week 4
d. week 7
submit

Step-by-step explanation:

This is an exponential equation that is solved by taking the natural log of both sides.  The equation is

If we are looking for x when f(x) = 64, then

Take the natural log of both sides:

The rules of logs allows us to bring the x down in front:

Divide both sides by ln(2) to get:

Do this on your calculator to get that x = 6.

You could also have just gone right to your calculator and started raising 2 to consecutive powers starting at like 3 or 4 to eventually get that 2 to the 6th power is equal to 64, but for the basics of solving log equations, you need to know how to do this.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
