9. What's the least common multiple (LCM) of 2, 6, and 8?

algol [13]

Answer:

Step-by-step explanation:

The LCM or least common multiple of these numbers is 24

To get 24, you list all the multiple of these numbers until they all share at least one

2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24

6, 12, 18, 24

8, 16, 24

They all share 24 so this is the LCM

Hope this helps

Find the equation of a tangent line at the point on a curve f(x) when x=e f(x)=xln(x)+x

alex41 [277]

$\bf f(x)=xln(x)+x\implies \cfrac{dy}{dx}=\stackrel{product~rule}{\left[1\cdot ln(x)+x\cdot \cfrac{1}{x}\right]}+1
\\\\\\
\left. \cfrac{dy}{dx}=ln(x)+2 \right|_{x=e} \implies 1+2\implies 3
\\\\\\
\textit{when x=e, what is \underline{y}?}\qquad f(e)=eln(e)+e\implies f(e)=2e
\\\\\\
(e~~,~~2e)\qquad\qquad \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-2e=3(x-e)
\\\\\\
y-2e=3x-3e\implies y=3x-e$
