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
Step-by-step explanation:
19 + 8 = n/3
27 = n/3 (multiply both sides with 3)
81=n
Answer:

Step-by-step explanation:
Use the exponential growth formula

Where A is the final amount in the account, P is the initial amount, r is the growth rate and t is the time in years
In this problem
We know that

So

Finally after 5 years the balance of the account is:
