The formula for compound interest is:
A=P(1+r/n)^(nt)
Where A represents the amount of money in the account after t years, P is the principal (investment), n is the number of compoundings per year, and r is the interest rate in decimal form.
P=11,100
r=.031
n=12 (monthly)
t=19
A=11,100(1+.031/12)^(12*19)
A=11,100(1+. 002583)^(228)
A=11,100(1.002583)^(228)
A=11,100(1.80082)
A=$19,989.10
200 is it the hundreds place so you round to there. The answer is 38,300 because 288 is closer to 300 than 200.

Hey do you need to show your work for these? I found an answer key
Step-by-step explanation:
We need to use law of cosines
c²=a²+b²-2abcos(C)
let x= angle xzy
plugging in what we have the equation looks like
17²=22²+20²-2*22*20*cos(x)
289=484+400-880cos(x)
.676136364=cos(x)
x=47.45754235
b.)
The smallest angle should be opposite to the smallest side
Using the law of cosines again we get
9²=13²+17²-2*13*17*cos(x)
81=458-442cos(x)
.852941176=cos(x)
x=31.46697634
Answer:
4 cups of milk are used with 3 cups of water
Step-by-step explanation:
The money has been in the account f<span>or 5 years. This means that the amount of deposit was increased for 5 times.
75*1.04*1.04*1.04*1.04</span>*1.04=75*1.04^5≈91.3 $
In this way i prefer to chose <span>D) $90.00 beacuse it's the nearest number</span>
