Find the annual percentage yield (APY) in the following situation. A bank offers an APR of 4.8% compounded daily. The annual per

sweet-ann [11.9K]

Answer:

4.92%

Step-by-step explanation:

First of all, recall that if you increase a number C in x%, then you will have $C+\frac{x}{100}C=C(1+\frac{x}{100})$

So increasing a number in x% is equivalent to multiply it by (1+x/100)

Now, suppose you have deposited $C where C is any amount > 0

If the bank offers an APR of 4.8% compounded daily, it means that your money increases $\frac{4.8}{365}\%=\frac{0.048}{365}$ daily.

So, after 365 days you will have

C multiplied by (1+0.048/365) 356 times, that is

(1) $C(1+\frac{0.048}{365})^{365}=C(\frac{365.048}{365})^{365}$

Now, you want to find a value x, such that C increased in x% equals the amount in (1).That would be the percentage your money increased in one year (APY)

$C(\frac{365.048}{365})^{365}=C(1+\frac{x}{100})\Rightarrow x=100[(\frac{365.048}{365})^{365}-1]$

Computing this amount, we get

x = 4.92 rounded to the nearest hundreth.

And the bank is offering an APY of 4.92%

wariber [46]

Answer:

$1/16$

Step-by-step explanation:

The formula for the sequence $a_n=\frac{1}{2}^n$ is used to find the $n$ th term of the sequence.

To find the fourth term, substitute $n=4$ :

$a_4=\left(\frac{1}{2})\right ^4,\\a_4=\frac{1^4}{2^4}=\boxed{\frac{1}{16}}$

Model 1.42 = 100% _% = _%

Aleks04 [339]

For the answer to the equation above, are you asking if what is the 1.42% of 100?
Because the 1.42 of 100% is 1.42

100/x=100/1.42
(100/x)*x=(100/1.42)*x multiply both sides of the equation by x
100=70.422535211268*x divide both sides of the equation by (
70.422535211268) to get x
100/70.422535211268=x 
1.42=x 
x=1.42
