What is the area of the figure?<br><br>a 28 yd<br><br>b 40 yd<br><br>c 52 yd<br><br>d 64 yd
Vilka [71]

Answer:

<h2>b. 40 yd²</h2>

Step-by-step explanation:

We have the square and the right triangle.

The formula of an area of a square:

A_{\boxed{}}=a^2

a - length of side

The formula of an area of a right triangle:

A_\triangle=\dfrac{ab}{2}

a,b - legs

We have:

SQUARE:

a = 4 yd

A_{\boxed{}}=4^2=16\ yd^2

RIGHT TRIANGLE:

a = 6 yd, b = 4 yd + 4 yd = 8 yd

A_\triangle=\dfrac{(6)(8)}{2}=(3)(8)=24\ yd^2

The area of the figure:

A=A_{\boxed{}}+A_\triangle\\\\A=16\ yd^2+24\ yd^2=40\ yd^2

Evaluate the surface integral ∫∫S F · dS for the given vector field F and the oriented surface S. In other words, find the flux
Strike441 [17]

Parameterize S by

\vec r(u,v)=u\,\vec\imath+v\,\vec\jmath+(7-u^2-v^2)\,\vec k

with 0\le u\le 1 and 0\le v\le1. Take the normal vector to be

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

Then the flux across S is

\displaystyle\iint_S\vec F\cdot\mathrm d\vec S

\displaystyle=\int_0^1\int_0^1(uv\,\vec\imath+(7-u^2-v^2)v\,\vec\jmath+(7-u^2-v^2)u\,\vec k)\cdot(\vec r_u\times\vec r_v)\,\mathrm du\,\mathrm dv

\displaystyle\int_0^1\int_0^1(2u^2v+(u+2v^2)(7-u^2-v^2))\,\mathrm du\,\mathrm dv=\frac{1343}{180}
