Nataly_w [17]

Answer:

y = -4

Step-by-step explanation:

Once you recognize the line as being horizontal, you know its equation will be ...

y = (some constant)

The value of the constant will correspond to the y-coordinate of the points the line goes through. It will also be the value of the y-intercept. Here, that value is -4, so the equation is ...

y = -4

Which of the following integrals represents the area of the region bounded by x = e and the functions f(x) = ln(x) and g(x) = lo

Neko [114]

Notice that

$\log_{1/e}x=\dfrac{\ln x}{\ln\frac1e}=\dfrac{\ln x}{-\ln e}=-\ln x$

$f(x)=\ln x$ and $g(x)=-\ln x$ intersect when $x=1$ . For all $x>1$ , we have $\ln x>0$ and $-\ln x$ , so $f(x)>g(x)$ . Then the area we want is given by the integral,

$\displaystyle\int_1^e\ln x-(-\ln x)\,\mathrm dx=2\int_1^e\ln x\,\mathrm dx$

or in terms of $\log_{1/e}x$ ,

$\displaystyle\int_1^e\ln x-\log_{1/e}x\,\mathrm dx$
