Answer:

<em>C. (-2, 7)</em>

Step-by-step explanation:

Put y = 7 to the equation x + y = 5:

x + 7 = 5 <em>subtract 7 from both sides</em>

x = -2

Find the derivative. <br> y = 5/ (2root4(x^3))

DedPeter [7]

$\bf y=\cfrac{5}{2\sqrt[4]{x^3}}\implies y=\cfrac{5}{2}\cdot x^{-\frac{3}{4}}\\\\
-----------------------------\\\\
\cfrac{dy}{dx}=\cfrac{5}{2}\left( -\cfrac{3}{4}x^{-\frac{3}{4}-1} \right)\implies 
\cfrac{dy}{dx}=\cfrac{5}{2}\left( -\cfrac{3}{4}x^{-\frac{7}{4}} \right)
\\\\\\
 
\cfrac{dy}{dx}=-\cfrac{15}{8}\cdot x^{-\frac{7}{4}} 
\implies 
\cfrac{dy}{dx}=-\cfrac{15}{8}\cdot \cfrac{1}{x^{\frac{7}{4}} }
\\\\\\
$

$\bf
\cfrac{dy}{dx}=-\cfrac{15}{8x^{\frac{7}{4}}}\implies 
\cfrac{dy}{dx}=-\cfrac{15}{8\sqrt[4]{x^7}}\\\\\\ \cfrac{dy}{dx}=-\cfrac{15}{8x\sqrt[4]{x^3}}

The volume of a cylinder is 4x3 cubic units and its height is x units.

Anastasy [175]

Answer:

The answer to your question is r = 2x

Step-by-step explanation:

Volume of a cylinder = V = π r² h

r = radius

h = height = x

Volume = 4x³

Then

r² = $\frac{volume}{\pi h}$

r² = $\frac{4x^{3} }{\pi x}$

r² = 4x²

r = 2x

Factor out 1/4 out of 1/4x+11/4

cluponka [151]

$\frac{1}{4} x+\frac{11}{4}$

we can rewrite it as

$\frac{1}{4}* x+\frac{1}{4}*11$

we can see that 1/4 is in multiple in both terms

so, we can factor it out

so, we get

$\frac{1}{4}( x+11)$ ..............Answer
