Integrate by parts, setting

$\begin{matrix}u=\ln R&&\mathrm dv=\dfrac{\mathrm dR}{R^2}\\\mathrm du=\dfrac{\mathrm dR}R&&v=-\dfrac1R\end{matrix}$

So the integral is

$\displaystyle\int_1^5\frac{\ln R}{R^2}\,\mathrm dR=-\dfrac{\ln R}R\bigg|_{R=1}^{R=5}+\int_1^5\frac{\mathrm dR}{R^2}$
$\displaystyle\int_1^5\frac{\ln R}{R^2}\,\mathrm dR=-\left(\frac{\ln5}5-\frac{\ln1}1)-\frac1R\bigg|_{R=1}^{R=5}$
$\displaystyle\int_1^5\frac{\ln R}{R^2}\,\mathrm dR=-\frac{\ln5}5-\left(\frac15-1\right)$
$\displaystyle\int_1^5\frac{\ln R}{R^2}\,\mathrm dR=\frac15(4-\ln5)$

Show work please for number 2

Pavlova-9 [17]

The combined distance between CD and DE is CE, so...

2x+4 + 6 = x+14 Simplify like terms..

2x + 10 = x + 14 Subtract x from both sides..

x + 10 = 14 Subtract 10 from both sides...

Proof: 2 (4) + 4 + 6 = 4 + 14

8 + 10 = 18

Can a right triangle be an isosceles triangle? A: Always B: Never C: Sometimes

frozen [14]

Yes, a right triangle can be an isosceles triangle sometimes.
C.

An isosceles triangle is a triangle with two or more sides of the same length. A right triangle is a triangle that has a right angle, therefore it is possible to have a right isosceles triangle.
