Question 72776: I am in dire need or assitance with the following questions and if anyone could assist me i WOULD BE SO GREATFUL!!!
(1)you are traveling North for 35km the you travel East 65km. how far are you from your starting point? N and E ca be considered the direstions of the y and x axis. Round to the tenths place.

1) Use Pythagoreans theorem
%2835%29%5E2%2B%2865%29%5E2=d%5E2
1225%2B4225=d%5E2
5450=d%5E2
d=sqrt%285450%29
d=73.8Approximately


2)To undo a exponent of 3, take a cube root
3sqrt%28729%29=3sqrt%28s%5E3%29
s=9So the side's length is 9


3)
A)
For annual compounding let n=1 and t=2 (two years)
use the equation
A=P%281%2Br%2Fn%29%5E%28nt%29Where A is return
A=10000%281%2B.1%29%5E2
A=12100So the annual return is $12,100
B)
For interest compounded quarterly let n=4 and t=2 (two years)
A=P%281%2Br%2Fn%29%5E%28nt%29
A=10000%281%2B.1%2F4%29%5E%288%29
A=10000%281.025%29%5E8
A=12184.03
C)
For interest compounded monthly let n=12 and t=2 (two years)
A=P%281%2Br%2Fn%29%5E%28nt%29
A=10000%281%2B.1%2F12%29%5E%282%2A12%29
A=10000%281.008333%29%5E24
A=12203.81
D)
For interest compounded daily let n=365 and t=2 (two years)
A=P%281%2Br%2Fn%29%5E%28nt%29
A=10000%281%2B.1%2F365%29%5E%282%2A365%29
A=10000%281.0002739%29%5E730
A=12213.05
So as the frequency of compounding increases it approaches a finite number. Notice how the increase gets smaller as we increase the frequency of compounding. So as the compounding frequency increases, it approaches a finite number. It actually approaches the continuous value of the continuous compound formula. Continuous compounding has the form
A=Pe%5E%28rt%29 Where e is a constant e=2.71828...
So if it was contiuously compounded for 2 years at 10% then
A=10000%282.718%5E%28.1%2A2%29%29
A=10000%281.221403%29
A=10000%281.221403%29
A=12214.03
So over 2 years it continuously compounds to $12,214.03
Hope this helps. Feel free to ask about any step.
