Answer:
16 27/50
Step-by-step explanation:
<h3>Answer:</h3>
242 weeks
<h3>Explanation:</h3>
After n weeks at annual interest rate r, the principal amount P will result in account balance A according to ...
... A = P·(1 +r/52)^n
Taking logs, we get
... log(A) = log(P) +n·log(1 +r/52)
... (log(A) -log(P))/log(1 +r/52) = n . . . . . solve for n
Filling in the given informatin, we have ...
... (log(6700) -log(5000))/log(1 +.063/52) = n ≈ 241.71
Rounded to the next higher number of weeks, this is 242 weeks.
Answer: 83.3
Explanation: tan 73= x/ 27
27 tan 73=x
x=88.313 = 88.3 feet
Think of how arithmetic sequences act. They start at a given number, and then they march up or down by the same distance each time. For example:
3, 7, 11, 15, 19, ...
this one marches up by 4 each time.
If this is plotted on a graph, the first point is (1,3), then (2,7), then (3,11), then (4,15) and so on. You'll notice that the slope is the same between all the points. In other words, you get a straight line! This is true for any arithmetic sequence.
28 is the "100%" in this equation so all you need to do is take the number that is not the 100% and divide it by the 100% number. so
21/28
