let the number be X

6x-19.85=29.77

6x=29.77+19.85

6x=49.62

x=8.27

Hope that helps :)

Answer:

To find the slope, use the formula rise/run or change in y/change in x

In this case, the slope is 5

To find y-intercept, substitue values for x and y

Step-by-step explanation:

-3 = 5(2) + b

-3 = 10 + b

-10 -10

-13 = b

Therefore, b is -13

So here's how the equation looks in slope-intercept form

y = 5x + -13

Find the area of the part of the circular paraboloid z = x2 + y2 where 0 x2 + y2 r2

amm1812

Parameterize the parabolic "cup" (call it $\mathcal S$ ) by

$\mathbf s(u,v)=\langle u\cos v,u\sin v,u^2\rangle$

with $0\le u\le r$ and $0\le v\le2\pi$ . Then the surface element is

$\mathrm dS=\|\mathbf s_u\times\mathbf s_v\|\,\mathrm du\,\mathrm dv=u\sqrt{1+4u^2}\,\mathrm du\,\mathrm dv$

and the area is given by the surface integral

$\displaystyle\iint_{\mathcal S}\mathrm dS=\int_{v=0}^{v=2\pi}\int_{u=0}^{u=r}u\sqrt{1+4u^2}\,\mathrm du\,\mathrm dv=\frac{\left((1+4r^2)^{3/2}-1\right)\pi}6$
