$\\ \rm\hookrightarrow \dfrac{8x^4y^3}{x^7y^4}$

a^m/a^n=a^m-n

$\\ \rm\hookrightarrow \dfrac{8x^{4-7}y^{3-4}}{}$

$\\ \rm\hookrightarrow 8x^{-3}y^{-1}$

$\\ \rm\hookrightarrow \dfrac{8}{x^3y}$

The volume of a cylinder is given by the formula v =<img src="https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D%20h" id="TexFormula1"

pashok25 [27]

Answer:

<h2>height = 110 feet </h2>

Step-by-step explanation:

From the question

Volume of the cylinder is given by

To find the height first make h the subject

That's divide both sides by πr²

We have

From the question

v = 35 ft³

r = 7 / 22

π = 22/7

Substitute the values into the above formula and solve for the height

That's

<h3> $h = \frac{35}{ \frac{22}{7} \times ({ \frac{7}{22} })^{2} } \\ = \frac{35}{ \frac{22}{7} \times \frac{49}{484} } \\ = \frac{35}{ \frac{7}{22} } \\ \ = 35 \div \frac{7}{22} \\ = 35 \times \frac{22}{7} \\ = 5 \times 22$ </h3>

We have the final answer as

Hope this helps you

If the simple interest on $5,000 for 9 years is $1,800, then what is the interest rate?

Law Incorporation [45]

$I = Prt\qquad \begin{cases} I=\textit{interest earned}\dotfill & \$1800\\ P=\textit{original amount deposited}\dotfill & \$5000\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\dotfill &9 \end{cases} \\\\\\ 1800=5000(\frac{r}{100})(9)\implies \cfrac{1800}{5000(9)}=\cfrac{r}{100}\implies \cfrac{1}{25}=\cfrac{r}{100} \\\\\\ 100=25r\implies \cfrac{100}{25}=r\implies \stackrel{\%}{4}=r$

Write the slope-intercept form of the equation of the line

Monica [59]

Answer:

y =-5x-17

Step-by-step explanation:

Slode-intercept is

y = mx + c

The first step is to find the slope, that is the m

To do that, use this formula

Y2 - y1

------------

X2- x1

And u will get - 5

Now since u got m, u also actually have y and x, those are the coordinates they gave u. U can choose either one,(-3, - 2) or (-4, 3), cuz they would give u the same answrs

So let's say I chose (-4, 3)

So x = - 4, y = 3

y=mx +c

3= - 5(-4) +c

C = - 17

Therefore your end product will be

y = - 5x - 17
