Answer:
$14,048.62
Step-by-step explanation:
The interest is 9% per year and compounded 3 times a year, so each compound will be 9%/3 = 3%
The time elapsed will be 15 years and the interest compounded 3 times a year, so the number of compounds happens will be = 15 years* 3 compounds/year= 45x compound.
So basically the money will get 3% interest 45 times. To put into the compounding interest formula, the final account balance will be:
A = P (1 + [ r / n ]) ^ nt
A= amount of the balance after a period of t
P= principal, the initial money deposit( $3,715)
r= rate(9%)
n= number of compound per unit of time(3 times per year)
t= time(15 years)
The calculation will be:
A = P (1 + [ r / n ]) ^ nt
A = ![$3,715(\frac{1+0.09}{3} )^{3*15}](https://tex.z-dn.net/?f=%243%2C715%28%5Cfrac%7B1%2B0.09%7D%7B3%7D%20%29%5E%7B3%2A15%7D)
A = $14,048.62
A) 4/36, or 1/9
b) 1-1/9=8/9
since there are 180 degrees in a triangle so :
65+72+y=180 add like terms
137 + y=180 now subtract 137
y= 180-137
y=43 degrees
Half of 126 is 63 because 63+63=126 and 126/2=63
