Step-by-step explanation:
Solution :
Given :
Principal amount deposited, P = $ 6000
Rate of interest, r = 5%
Number of years, t = 4 years
When the deposited amount is compounded semiannually, i.e. n = 2
Therefore,
Future value,



= 6000 x 1.2184
= 7310.4
Therefore, after 4 years there will be $ 7310.4 in the amount when compounded semi annually.
When the deposited amount is compounded quarterly, i.e. n = 4
Therefore,
Future value,



= 6000 x 1.219889
= 7319.334
Therefore, after 4 years there will be $ 7319.334 in the amount when compounded quarterly.
When the deposited amount is compounded monthly, i.e. n = 12
Therefore,
Future value,



= 6000 x 1.22089
= 7325.34
Therefore, after 4 years there will be $ 7325.34 in the amount when compounded monthly.
-sqa(3.24-sqa(1.44+sqa(12.25)))
= -sqa(3.24-sqa(4.94)) (since sqa(1.44+sqa(12.25))=sqa(4.94))
=-sqa(3.24-2.22261)
= - sqa(1.01739)
= - 1.00866
Answer:
1. 28
2. b = 7.06
2. c = 3.76
Step-by-step explanation:
1. m < C = 90 - B = 90 - 62 = 28 degrees
2. sin B = opposite/hypotenuse
sin (62o) = b/8
b = 8 x sin (62o) = 8 x 0.883 = 7.06
3. sin C = opposite/hypotenuse
sin (28o) = c/8
c = 8 x sin (28o) = 8 x 0.4695 = 3.76
6/7 times 6/7 equals 36/49
