Answer:
Relative minima at , and relative maxima DNE.
Step-by-step explanation:
The given function is f(x) = x (x + 7) ...... (1)
We have to calculate the relative maxima and relative minima at point (x, y).
Rearranging the function given above we get.
⇒
Now, this is an equation of parabola having vertex at and the axis is parallel to positive Y-axis.
Therefore, the function(1) has a relative minima at , and the relative maxima DNE. (Answer)
Answer:
(a) The future value after 9 years is $7142.49.
(b) The effective rate is .
(c) The time to reach $13,000 is 21.88 years.
Step-by-step explanation:
The definition of Continuous Compounding is
If a deposit of dollars is invested at a rate of interest
compounded continuously for
years, the compound amount is
(a) From the information given
Applying the above formula we get that
The future value after 9 years is $7142.49.
(b) The effective rate is given by
Therefore,
(c) To find the time to reach $13,000, we must solve the equation
