An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.
The operation's arity is determined by the number of operands.
A mathematical action is called an operation.
Mathematical operations include addition, subtraction, multiplication, division, and finding the root.

So, the area of the figure:

Where x = 4, so the expression will become:

x² + x² + x + x

Now, do the mathematical operations to get the area of the figure as follows:

x² + x² + x + x
4² + 4² + 4 + 4
16 + 16 + 8
40

Therefore, using mathematical operations we can conclude that the area of the given figure is 40 units².

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.

I added a picture : Determine which of the lines, if any, are parallel or perpendicular. Explain.

exis [7]

Answer:

1. line a and c and parallel. line b is perpendicular with line a and c. 2. line b and c and parallel. line a is perpendicular to lines b and c. 3. y= -3x + 3 4. y=(5/3)x - 9

Step-by-step explanation:

To find parallel and perpendicular, make the slope opposite and find b by plugging in the points. Parallel is the same slope.
