Find the area of the part of the paraboloid z = 9 - x^2 - y^2 that lies above the xy-plane.
svetoff [14.1K]

Parameterize this surface (call it S) by

\vec r(u,v)=u\cos v\,\vec\imath+u\sin v\,\vec\jmath+(9-u^2)\,\vec k

with 0\le u\le3 and 0\le v\le2\pi. Take the normal vector to S to be

\vec r_u\times\vec r_v=2u^2\cos v\,\vec\imath+2u^2\sin v\,\vec\jmath+u\,\vec k

Then the area of S is

\displaystyle\iint_S\mathrm dA=\iint_S\|\vec r_u\times\vec r_v\|\,\mathrm du\,\mathrm dv

=\displaystyle\int_0^{2\pi}\int_0^3u\sqrt{1+4u^2}\,\mathrm du\,\mathrm dv

=\displaystyle2\pi\int_0^3u\sqrt{1+4u^2}\,\mathrm du=\boxed{\frac{37\sqrt{37}-1}6\pi}

Given f(x) = 4x - 6 and g(x) = f(2x), write an equation for g.
AysviL [449]

f(x)=4x-6

g(x) = f(2x)

Substitute 2x into the first equation, which you get

f(2x)=8x-6

<h2><u><em>So, g(x)=8x-6</em></u></h2>

URGENT!!
slava [35]

Answer:

a. 3/5 liters per hour

b .06 hours

Step-by-step explanation:

Change 40 minutes to a fraction of an hour

40 minutes/ 60 minutes = 2/3 hour

It takes 1 2/3 hours to fill the container

Changing to an improper fraction

(3*1+2)/3 = 5/3 hours

We want liters per hour

1 liter per 5/3 hours

1 ÷ 5/3

Copy dot flip

1 * 3/5 = 3/5 liters per hour

Change 100 ml to liters

We know 1000 ml  = 1 lt

100 ml * 1 lt/1000 ml = .1 lt

So 100 ml = .1 lts

.1 lt * 3/5 lt per hour

Changing the fraction to a decimal

.1 lt * .6 lt per hour

.06 hours
