Answer:
b) π /16 (1-1/e^2)
Step-by-step explanation:
For this case we have the following limits:
And we have semicircles perpendicular cross sections.
The area of interest is the enclosed on the picture attached.
So we are assuming that the diameter for any cross section on the region of interest have a diameter of
And then we can find the volume of a semicircular cross section with the following formula:
And for th volum we can integrate respect to x and the limits for x are from 0 to 1, so then the volume would be given by this:
And evaluating the integral using the fundamental theorem of calculus we got:
And then the best option would be:
b) π /16 (1-1/e^2)
We have been given that a credit card had an APR of 14.86% all of last year, and compounded interest daily. We are asked to find the effective interest rate of the credit card.
We will use effective interest rate formula to solve our given problem., where
= Annual interest rate in decimal form,
m = Number of times interest is compounded per year,
n = Number of compounding periods the rate is required for.
We need rate for 1 year, so n will be 365 times 1.
Let us convert effective rate in percent.
Therefore, the effective interest rate would be .
