Evaluate the surface integral. s xy ds s is the triangular region with vertices (1, 0, 0), (0, 8, 0), (0, 0, 8)

zmey [24]

Parameterize $S$ by

$\vec s(u,v)=(1-u)v\,\vec\imath+8uv\,\vec\jmath+8(1-v)\,\vec k$

with $0\le u\le1$ and $0\le v\le1$ .

Then the surface element is

$\mathrm dS=\|\vec s_u\times\vec s_v\|\,\mathrm du\,\mathrm dv=8\sqrt{66}\,v\,\mathrm du\,\mathrm dv$

and the surface integral is

$\displaystyle\iint_Sxy\,\mathrm dS=8\sqrt{66}\int_0^1\int_0^18(1-u)uv^3\,\mathrm du\,\mathrm dv=\boxed{8\sqrt{\dfrac{22}3}}$

Determine if the function f(x) = 4√x − 3x satisfies the Mean Value Theorem on [4, 49]. If so, find all numbers c on the interval

Vedmedyk [2.9K]

Answer:

Step-by-step explanation:

The mean value theorem states that for a continuous and differentiable function on a interval there exists a number c from that interval, that

$f'(c)=(f(b)-f(a))/(b-a)$

First we must determine the endpoints:

$f(49)=-119$

$f(4)=-4$

We find the derivative of the function, f'(c)

$f'(c)=3+2\sqrt{c}$

Therefore:

$3+2\sqrt{c}=((-119)-(-4))/((49)-(4))$

Simplify:

$3+2\sqrt{c}=-23/9$

$c=81/4$

PLEASE HELP ME... ANYONE.... i am begging you. i will mark brainiest, whatever you want. please help...

Mice21 [21]

Answer:

Step-by-step explanation:

<h3>We are given:</h3>

Monday x 2 = Tuesday

Tuesday - 6 = Wednesday

Lets say

Monday = m

Tuesday = t

Wednesday = w

m = m

2m = t

2m - 6 = w

Combine like terms: 5m - 6 = 19

Add 6 to both sides

5m = 25

Divide both sides by 5

m = 5

Plug it in the equations.

<em>Monday = 5</em>

<em>Tuesday = 10</em>

<em>Wednesday = 4</em>
