Suppose you want to have $400,000 for retirement in 35years. Your account earns 4% interest.

Sedaia [141]

$\begin{equation*} \$437.76 \end{equation*}$

1) This is a question for Annuity usage. Note that we'll need the following formula below:

$\begin{gathered} P=\frac{A(\frac{r}{n})}{\lbrack(1+\frac{r}{n})^{nt}-1\rbrack} \\ P=\frac{400000(\frac{0.04}{12})}{\lbrack(1+\frac{0.04}{12})^{12\cdot35}-1\rbrack} \\ P=\frac{400000\cdot\frac{0.04}{12}}{\left(1+\frac{0.04}{12}\right)^{35\cdot\:12}-1} \\ P=\frac{400000\cdot\frac{0.04}{12}}{1.0033^{420}-1} \\ P=437.76563...\approx\$437.76 \end{gathered}$

Note that P is the value you'll need to deposit each month so that in 35 years you'll have $400,000 for your retirement.

If you bring every horizontal piece down they will cover whole side .also vertical pieces will cover whole side ,too. so 17+17=34

Answer:

E. 50%

Step-by-step explanation:

The shaded regions in the bottom can be 'moved' to the top since those pieces are the same size and if you do that, they cover the entire top half

Coordinates (x, y)
Midpoint Formula: $\displaystyle (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Step-by-step explanation:

Step 1: Define

Point A(8, 2) → x₁ = 8, y₁ = 2

Point B(3, 8) → x₂ = 3, y₂ = 8

Step 2: Find Midpoint

Simply plug in your coordinates into the midpoint formula to find midpoint

Substitute in points [Midpoint Formula]: $\displaystyle (\frac{8+3}{2},\frac{2+8}{2})$
[Midpoint] [Fraction] Add: $\displaystyle (\frac{11}{2},\frac{10}{2})$
[Midpoint] Divide: $\displaystyle (\frac{11}{2},5)$
