What is the x-intercept of the graph?

Umnica [9.8K]

Answer: (6,0)

Step-by-step explanation: To find the x-intercept, we plug a 0 in for y.

So we have 2x - 3(0) = 12.

Simplifying from here, we have 2x = 12.

Now divide both sides by 2 and we get <em>x = 6</em>.

So our x-intercept is 6.

This means that our line crosses the x-axis 6

units to the right of the origin or at the point (6,0).

1) $\overline{AB} \perp \overline{BD}$ , $\overline{AB} \cong \overline{DB}$ , $\overline{AC} \cong \overline{DE}$ (given)

2) $\angle ABD$ is a right angle (perpendicular lines form right angles)

3) $\triangle ABD$ and $\triangle DEB$ are right triangles (a triangle with a right angle is a right angle)

4) $\triangle ABD \cong \triangle DEB$ (HL)

5) $\angle ACB \cong \angle DEB$ (CPCTC)

Find the surface area of the part of the sphere x2+y2+z2=81 that lies above the cone z=x2+y2−−−−−−√

TiliK225 [7]

Parameterize the part of the sphere by

$\mathbf s(u,v)=(9\cos u\sin v,9\sin u\sin v,9\cos v)$

with $0\le u\le2\pi$ and $0\le v\le\dfrac\pi4$ . Then

$\mathrm dS=\|\mathbf s_u\times\mathbf s_v\|=81\sin v\,\mathrm du\,\mathrm dv$

So the area of $S$ (the part of the sphere above the cone) is given by

$\displaystyle\iint_S\mathrm dS=81\int_{v=0}^{v=\pi/4}\int_{u=0}^{u=2\pi}\sin v\,\mathrm du\,\mathrm dv=81(2\pi)\left(1-\dfrac1{\sqrt2}\right)=(162-81\sqrt2)\pi$
