Could you please show work so I can understand the question

 

13. Find x as a function of z when z³Â Â· e^x = 2. Then calculate the rate of change of x with respect to z.

14. Find x as a function of y when y = y²Â + ln x. Then calculate the rate of change of x with respect to y

15. Find the slope of the line tangent to y = 5^x at x = 1

17. Find the maximum value of f(x) = ln(9 − x²). Suggestion: first consider the domain of f.

20. Find the maximum value of f(x) = ln(1 + x − x²Â ) one the interval [2, 6].

21. The value of a certain machine at time t is V = 50, 000e^−0.08t dollars. (Here t is measured in years and t ≥ 0). At what time will the machine have a value of $10,000?

22. The value of a certain machine at time t is V = 50, 000e^−0.08t dollars. (Here t is measured in years and t ≥ 0). At what rate is the value changing over time?

24. The population of a certain country, in millions, at time t years is P(t) = 55e^0.03t . At what rate is the population increasing with time? What is the population’s relative rate of growth?

25. The capital in a certain country, in billions of dollars, at time t years is K(t) = 800e^0.02t . At what rate is capital increasing with time? What is the relative rate of growth of capital?

28. The population of a certain country, in millions, at time t years is P(t) = 12e^0.015t . The capital, in billions of dollars, is K(t) = 800e^0.03t . Suppose that personal income is W(t) = 0.01K(t)/P(t). Is personal income increasing over time?
