Answer:
$3644675.9
Step-by-step explanation:
The initial investment is $100000. The interest rate is 12%.
We are asked to determine the final amount the investment will become after 30 years if the interest is compounded weekly.
The weekly interest rate is %.
Assuming 1 year equivalent to 52 weeks.
Hence, using the formula of compound interest the final sum will be
= $3644675.9 (Approximate)

In calculus, we use derivatives to find the instantaneous rate of change at any point on a graph. To find the average rate of change, we just find the slope of the secant line that intercepts two points on the graph.
We find slope with the following equation:
In this case, we are looking for the slope from x = -1 to x = 1. We have both x values, so next we need the y values.
F(-1) = (-1)^2 - (-1) - 1 = 1
F(1) = (1)^2 - (1) - 1 = -1
Now plug in the x and y values to find the slope:
The answer is -1.

Step-by-step explanation:
The formula needed to solve this question by hand is:
256^(5/8) = 8th root of 256^5
256^(5/8) = 8th root of 1280
<u>256^(5/8) = 32</u>
