Find the integral, using techniques from this or the previous chapter.<br> ∫x/√16+8x^2 dx.

chubhunter [2.5K]

$\displaystyle\int\frac x{\sqrt{16+8x^2}}\,\mathrm dx$

Let $u=16+8x^2\implies\mathrm du=16x\,\mathrm dx$ . Then the integral becomes

$\displaystyle\frac1{16}\int\frac{\mathrm du}{\sqrt u}\,\mathrm du=\frac18\sqrt u+C$

$=\dfrac18\sqrt{16+8x^2}+C$

Answer:

He is incorrect. Ray RO and ray RL are not opposite rays.

Step-by-step explanation:

Two angles are linear pair if they are supplementary and share a leg.

∠ORP and ∠LRP are not supplementary, because ray RO and ray RL are not opposite rays.

Therefore, ∠ORP and ∠LRP are not linear pair.

Equation

(3x - 1) * 3 = 12*(x -2) Remove the brackets.

Solution

9x - 3 = 12x - 24 Add 24 to both sides.

9x - 3 + 24 = 12x - 24 + 24 Combine

9x + 21 = 12x Subtract 9x from both sides

9x - 9x +21 = 12x - 9x

21 = 3x Divide by 3

21/2 = 3x/3

7 = x

Find QR
