Find the unit vector in the direction of u = (-3,2).

DENIUS [597]

$\bf \textit{unit vector for }(a,b)\implies \left( \cfrac{a}{\sqrt{a^2+b^2}}~~,~~\cfrac{b}{\sqrt{a^2+b^2}} \right)\\\\
-------------------------------\\\\
(-3,2)\qquad \stackrel{unit~vector}{\implies }\qquad \left( \cfrac{-3}{\sqrt{(-3)^2+2^2}}~~,~~\cfrac{2}{\sqrt{(-3)^2+2^2}} \right)
\\\\\\
\left( -\cfrac{3}{\sqrt{13}}~~,~~ \cfrac{2}{\sqrt{13}}\right)\\\\
-------------------------------$

$\bf \textit{and now let's \underline{rationalize} the denominator for each}
\\\\\\
-\cfrac{3}{\sqrt{13}}\cdot \cfrac{\sqrt{13}}{\sqrt{13}}\implies -\cfrac{3\sqrt{13}}{13} \qquad \qquad \qquad \qquad \cfrac{2}{\sqrt{13}}\cdot \cfrac{\sqrt{13}}{\sqrt{13}}\implies \cfrac{2\sqrt{13}}{13}
\\\\\\
\textit{and written in \underline{ai+bj form}}\qquad -\cfrac{3\sqrt{13}}{13}i~~~~+~~~~\cfrac{2\sqrt{13}}{13}j$

What is the exact volume of a sphere with a diameter of 18 cm? <img src="https://tex.z-dn.net/?f=%20%5Cpi%20" id="Te

Vesna [10]

Sphere Volume = ( π •diameter^3) / 6

Sphere Volume = 3.14159 * 18^3 / 6

Sphere Volume = 3.14159 * 5,832 / 6

Sphere Volume = 3.14159 * 972

Sphere Volume = 3,053.63

F(x)=2x+3/4x+5 find f(-9)

mylen [45]

$\implies {\blue {\boxed {\boxed {\purple {\sf { f(-9)= 0.48}}}}}}$

$\large\mathfrak{{\pmb{\underline{\orange{Step-by-step\:explanation}}{\orange{:}}}}}$

$f(x) = \frac{2x + 3}{4x + 5} \\$

For $f(-9)$ , put " $-9$ " for every value of " $x$ ".

$↬f( - 9) = \frac{2( - 9) + 3}{4( - 9) + 5}\\$

$↬ f(-9) = \frac{ - 18 + 3}{ - 36 + 5} \\$

$↬ f(-9) = \frac{ - 15}{ - 31}\\$

$↬ f(-9)= \frac{15}{31}\\$

$↬f(-9)= 0.48\\$

How are liquid assets different from other assets?What is the main difference in the way that "earned income" and "capital gains

BabaBlast [244]

Answer: All assets represent money, but only liquid assets can be easily turned into spendable money.

Earned income is money you received for a job performed and capital gains are profits from investments.

Step-by-step explanation: Because this is the definition of liquid assets: A liquid asset is cash on hand or an asset that can be readily converted to cash. An asset that can readily be converted into cash is similar to cash itself because the asset can be sold with little impact on its value.

-Earned income refers to salary, bonuses, commissions, tips that you receive because of a job that you have done from an employer or your business.

-Capital gains refer to money that you receive because of the sale of a capital asset like stocks or real estate.
