Amiraneli [1.4K]

To answer this item, note that what needs to be done is to substitute -4 to all x's in the equation. That is,
F(x) = 2^x
will become,
F(-4) = 2^(-4) = 1/16 or 0.0625

Which are rational and irrational? Thanks in advance :)

DochEvi [55]

Answer:

$3\frac{1}{2}-rational$

$\pi -irrational$

$-\frac{2}{3}-rational$

$\sqrt{16} -rational$

$\sqrt{3} -irrational$

$18-rational$

$0.625-rational$

$0.987987987...-rational$

Step-by-step explanation:

Rational numbers:

-are all numbers you can write as a quotient of integers $\frac{a}{b}$ , $b\neq 0$

-include terminating decimals. For example, $\frac{1}{8}=0.125$

-include repeating decimals. For example, $\frac{1}{3} =0.33333....$

Irrational numbers:

-have decimal representations that neither terminate nor repeat. For example, $\sqrt{2}=1.414213....$

-cannot be written as quotients of integers

A realtor's commission is directly proportional to the selling price of a house. Mr. Wiley earned a commission of $9,200 on a ho

Salsk061 [2.6K]

<span>Mr. Wiley earned a commission of $9,200 on a house that sold for $184,000.
</span><span>At this rate, Mr. Wiley's commission be on a house that sells for $250,000 = ?
commission = price of house sold
$9,200 = $184,000
multiply both sides with $250,000
$9,200 x </span>$250,000 = $184,000 x $250,000
when the price is $250,000, the commission will be;
($9,200 x $250,000) / $184,000 = $250,000
$2300000/$184 = $250,000
$12,500 = $250,000
Thus, the commission is $12,500.

two ships leave a port at the same time. the first ship sails on a bearing of 55° at 12 knots (natural miles per hour) and the s

Korvikt [17]

Answer:

37.59 nautical miles

Explanation:

Distance = Speed x Time

The speed of the first ship = 12 knots

Thus, the distance covered after 1.5 hours

$\begin{gathered} =12\times1.5 \\ =18\text{ miles} \end{gathered}$

The speed of the second ship = 22 knots

Thus, the distance covered after 1.5 hours

$\begin{gathered} =22\times1.5 \\ =33\text{ miles} \end{gathered}$

The diagram representing the ship's path is drawn and attached below:

The angle at port = 90 degrees.

The triangle is a right triangle.

Using Pythagorean Theorem:

$\begin{gathered} c^2=a^2+b^2 \\ c^2=18^2+33^2 \\ c^2=324+1089 \\ c^2=1413 \\ c=\sqrt[]{1413} \\ c=37.59\text{ miles} \end{gathered}$

The two ships are 37.59 nautical miles apart after 1.5 hours.
