Answer:

$17,277.07

Step-by-step explanation:

Present value of annuity is the present worth of cash flow that is to be received in the future, if future value is known, rate of interest is r and time is n then PV of annuity is

PV of annuity = $\frac{P[1-(1+r)^{-n}]}{r}$

= $\frac{3000[1-(1+0.10)^{-9}]}{0.10}$

= $\frac{3000[1-(1.10)^{-9}]}{0.10}$

= $\frac{3000[1-0.4240976184]}{0.10}$

= $\frac{3000(0.5759023816)}{0.10}$

= $\frac{1,727.7071448}{0.10}$

= 17,277.071448 ≈ $17,277.07

Solve the equation |5-x|=2

Svet_ta [14]

Hi,

Work:

Equation;

$|5 - x| = 2$

Rewrite the absolute value equation as two separate equations, one positive and the other one negative.

$5 - x = 2 \\ 5 - x = - 2$

Solve both equations for x.

$x = 3 \\ x = 7$

Final solutions:

$x1 = 3 \\ x2 = 7$

Hope this helps.
