Given that Meg invested $ 16,000 in a savings account, if the annual interest rate is 6%, to determine how much will be in the account in 5 years for quarterly compounding, the following calculation must be performed:
16,000 x (1 + 0.06 / 4) ^ 5x4 = X
16,000 x 1,015 ^ 20 = X
16,000 x 1.34685500 = X
21,549.68 = X
Therefore, in 5 years the account will be $ 21,549.68.
Let p (x) = 4x^4-13x^2-2x The zero of x-2 is 2 putting x = 2 in p (x), we get, p (2) = 4×2^4-13×2^2-2×2 = 64 - 52 - 4 = 64 - 56 = 8 Therefore, remainder = 8
You can multiply by 12 because to get rid of the fractions all terms should be divided by the LCM (ie the smallest multiple that is exactly divisible by 2, 4 and 3)
Multiples of 3 = 3, 6, 9, 12
Multiples of 4 = 4, 8, 12, 16
Multiples of 2 = 2, 4, 6, 8, 10, 12
Therefore the fractions should be multiplied by 12
