Let x be total hours of battery life. We have been given that battery life of Vera's phone is down to 2/5. So remaining battery life,

We have been also given that it drains another 1/9 every other hour. Now let us substitute our given information into an equation.

Now we will solve for x.


Let us convert 2/5 into minutes. We know 1 hour has 60 minutes.

Therefore, remaining battery life will be 5 hours and 24 minutes.
Answer:
The relation represents a growth when b>1 and a decay when 0<b<1
Step-by-step explanation:
Any function in the form
, where a > 0, b > 0 and b not equal to 1 is called an exponential function with base b. If 0 < b < 1. It is an example of an exponential decay. The general shape of an exponential with b > 1 is an example of exponential growth. An exponential function is expressed in the form
The relation represents a growth when b >1 and a decay when 0<b<1.
