explain how to find the growth rate of this equation:

y=5(1.034)^x

To find A when given the growth rate, you convert the percentage to a decimal and then add 1. so to do it the other way around, you subtract 1 to get 0.034. then you convert to a percentage to get a 3.4% growth rate.

The cat enjoys unrolling the toilet paper roll, and as it keeps unrolling the toilet paper the speed increases by a certain percent every 10 seconds. There are 100 squares on the roll, and in 20 seconds the whole was unrolled. The cat started out unrolling it with 1 square per second. this can be modeled with 100=a(b)^x. fill in a and b using the information to make and equation. 
A=1

B=10

the equation is y=(10)^x

bacteria started to grow on Jason's shower floor. it increases by a certain percent each day, but Jason ignores it because he will "deal with it later" His shower floor is 7.5 square feet in area. In 4 days the bathtub was completely covered and Jason started showering at his gym. What is the equation for this situation. (Hint: on day 3, about 3/5 of the floor was covered. And we will take the closest answer due to the fact that a lot of the values were rounded)
y=(1.65)^x
