Answer:
His actual interest rate per year is 24.04%.
Step-by-step explanation:
Given : where n is the number of compounding periods per year. Benny’s credit card APR is 21.55% compounded daily.
To find : What is his actual interest rate per year—that is, his EAR?
Solution :
The formula of EAR is
Here, APR = 21.55%=0.2155
n=365 (compounded daily)
Substitute the value,
Therefore, His actual interest rate per year is 24.04%.

Step-by-step explanation:
Lines that are perpendicular will have slopes that are opposite reciprocals. The slope of y=7/6x+4 is 7/6. So we need to find the opposite reciprocal of 7/6. Opposite would make the number negative and reciprocal would switch the numerator with the denominator. So the slope of any line reciprocal to y=7/6x+4 would be -6/7. Then you can use any real number as the y intercept for the new equation.
An acceptable answer would be
y= -6/7x+10
But the number 10 could be replaced by any real number.
Answer:
Step-by-step explanation:
The volume of a cylinder is:
where is the radius and is the height.
The height is 4 inches greater that the radius, so:
Substituting this in the formula for volume:
the volume is
thus:
Dividing everything between pi:
We can see that the solution for this is
since
We have the radius, now we find the height:
