Answer:

278.773622 or 300 if rounded

Step-by-step explanation:

The area of a circle is:

π (Pi) times the Radius squared:

A = π r2

or, when you know the Diameter:

A = (π/4) × D2

or, when you know the Circumference:

A = C2 / 4π

Let $f(x)=e^{-1/x}$ . Then $f'(x)=\frac1{x^2}e^{-1/x}>0$ for all $x\ge2$ , so $f$ is strictly increasing. As $x\to\infty$ , $e^{-1/x}\to e^0=1$ , so $f$ is bounded above by 1. This is to say,

$e^{-1/x}$

and the integral of $\frac1{x^2}$ converges over the same domain, so this integral must also converge by comparison.

We have, by setting $y=-\frac1x$ ,

$\displaystyle\int_2^\infty\frac{e^{-1/x}}{x^2}\,\mathrm dx=\int_{-1/2}^0e^y\,\mathrm dy=e^0-e^{-1/2}=1-\frac1{\sqrt e}$

Can some one help me.

Answer:

The slope is 3

Step-by-step explanation:

m = rise/run

m = (y2 - y1)/(x2-x1)

points: (0,-5), (1,-2)

m = ((-5) - (-2))/ ((0) - (1))

m = (-5 + 2)/ (-1)

m = -3/-1

m = 3
