Answer:

1) n^2 – 3 n + 8 4^2 – 3*4 + 8 = 12

2) (x^2 – 4 y) / 2 (16 + 12) / 2 = 14

3) 4 * |-7 – 2| = 4 * 9 = 36 Abs -9 = 9

4) 19 – x^2 = 19 – 25 = -6 (-5)^2 = 25

5) S^2 t – 10 = -8^2 * ¾ -10 = 64 * ¾ - 10 = 38

6) 4 p^2 + 7 q^3 = 4 * 9 + 7 * (-8) = - 20 (-2)^3 = -8

Abby Mia wants to know how much must be deposited in her local bank today so that she will receive yearly payments of $18,000 fo

muminat

We are not given tables, so will just use the amortization formula.
$P=\frac{A*((1+i)^n-1)}{i*(1+i)^n}$
where
P=amount to be deposited today, to be found
A=amount withdrawn each year=18000
i=Annual interest=9%
n=number of years = 20

Substituting values,
$P=\frac{A*((1+i)^n-1)}{i*(1+i)^n}$
$=\frac{18000*((1+0.09)^{20}-1)}{0.09*(1+0.09)^{20}}$
=164313.82 to the nearest cent
