Answer:
7.87 years
Step-by-step explanation:
#First we determine the effective annual rate based on the 9% compounded semi annual;
#We then use this effective rate in the compound interest formula to solve for n. Given that the principal doubles after 2 yrs:
Hence, it takes 7.87 years for the principal amount to double.
Answer:
5 5/7

Answer:
C
Step-by-step explanation:
A) not true. Sin A = some decimal

B) Sin55 = cos55 is not true either only sin(45) = cos(45) is true. So B is not true.
That leaves C. I think if you check it, you'll find it is right. sin(A) = cos(90 - A)
