Answer:
The equation that models the situation is 
Step-by-step explanation:
Exponential equation:
An exponential equation has the following format:

In which A(0) is the starting value and r is the growth rate, as a decimal.
Starting value of 13 and a growth rate of 0.78%.
This means that 
Write an equation to model the situation.



The equation that models the situation is 
Step-by-step explanation:
sin(x) = 1
cos(x) = 0
tan (x) = <u>sin(x)</u>
cos(x)
tan(x) = 1/ 0
Which can be considered as undefined or infinite
