Answer:
<h2>S = 11.4</h2>
Step-by-step explanation:
To find s we use the cosine rule
That's
s² = SU² + ST² - 2(SU)(ST) cos S
From the question
SU = 5
ST = 13
S = 60°
Substituting the values into the expression we have
s² = 5² + 13² - 2(5)(13) cos 60
s² = 25 + 169 - 130cos 60
s² = 194 - 65
s² = 129
Find the square root of both sides
s= √129
s = 11.357816
We have the final answer as
<h3>s = 11.4 to the nearest tenth</h3>

Answer:
A is approximately 200.86 square units.
Step-by-step explanation:
Answer:
C. But be careful. It depends if you have been told what I was having trouble with.
Step-by-step explanation:
The question is a little unclear. If the actual interest is constant for all situations, the answer is C. The more times you compound, the more interest you will accumulate. Banks don't do it that way. It they compound every three months, then they cut the interest rate by a quarter.
So the interest would look like (1 + 0.022/4)*principle. Whoever made the question has to make clear what is going on. My guess is the intended answer is C.
