How to solve all of the practice problems

I have a final on Wed & this class online but this a print of the practice I don’t know how to do it I’ve been doing the textbook practices but i’m a visual learner so I need someone to solve these and show me the work please I don’t have time to go back to tutoring on campu

1. Solve: 40(0.996)’ = 4000
gebra
2. Solve:
1500 + (60.04x)= 4500
3. Solve: 106x-1 = 674
4. Let f(x)= 2x+3, 8(x)= x – 3. Use definition to check if f and g are inverse
functions
(3x – 4)
5. Expand In
(x+4)*(x+6)
6. Write into one logarithm In(2x – 1)-91n(x + 3)+2 In(2x + 4)
Let f(x) = 4x
7. Does f have an inverse function? Why?
8. If it does, find its inverse function
2x-1
9. Find the inverse of f(x) =
The number of bacteria in a culture is N(x) 1470(1.996)”, where x is measured in
hours
x +3
10. What is the initial population of the culture?
11. How many bacteria will the culture contain after 7 hours?
12. After how many hours will the culture contain 46590 bacteria?

14. How long will take for $30,000 to become $60,000 if it is invested at an annual
interest rate of 7%, compounded continuously for 20 years?
Quarterly
Weed for 20 years?
