Move the decimal So that you have one number to the left of it. Count the number of spaces it was moved. Remove all trailing 0’s.

Multiply by 10 raised to the power of the number is spaces the decimal was moved.

Answer:

C = 125

Step-by-step explanation:

Since a straight line is 180 degrees. We can conclude that:

10x + 15 + 5x = 180

And that:

C = 10x + 15

First we need to find the value of x to find C. So,

10x + 15 + 5x = 180

15x + 15 = 180

- 15 -15

15x = 165

15x/15 = 165/15

x = 11

So now, we need to substitute the values of x into C and solve it.

C = 10(11) + 15

= 110 + 15

= 125

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

alex41 [277]

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