nexus9112 [7]

Answer:

In 5 years the account will be $ 21,549.68.

Step-by-step explanation:

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.

GenaCL600 [577]

Answer:

slope = 0

Step-by-step explanation:

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (4, - 1 ) and (x₂, y₂ ) = (3, - 1 )

m = \frac{-1-(-1)}{3-4} = \frac{-1+1}{-1} = \frac{0}{-1} = 0
