Use the sine function here.

Each medal is different and is handed out depending on the outcome of the race/order of the racers, so we're counting the number of permutations. 4 medals are given to 4 runners, so there are
possible ways to do it.

Answer:
The amount is $8358.7 and the interest is $3858.7.
Step-by-step explanation:
STEP 1: To find amount we use formula:
A=P(1+rn)n⋅t
A = total amount
P = principal or amount of money deposited,
r = annual interest rate
n = number of times compounded per year
t = time in years
In this example we have
P=$4500 , r=7% , n=2 and t=9 years
After plugging the given information we have
A=4500(1+0.072)2⋅9A=4500⋅1.03518A=4500⋅1.857489A=8358.7
STEP 2: To find interest we use formula A=P+I, since A=8358.7 and P = 4500 we have:
Answer:
440
Step-by-step explanation:
305+ (45*3)= 440
350+ (30*3)= 440
