We want to find the maximum and minimum values of f(x, y) = 10x2 + 11y on the disk D: x2 + y2 < 1.

dolphi86 [110]

If you're just focusing on the boundary, it's the circle $x^2+y^2=1$ . Parameterize it by taking $x=\cos t$ and $y=\sin t$ , with $0\le t\le2\pi$ . Then $f(x,y)$ reduces to a univariate function $g(t)$ :

$f(x,y)=10x^2+11y\iff g(t)=f(\cos t,\sin t)=10\cos^2t+11\sin t$

Then you can find any extrema on the boundary by checking the critical points of $g$ .

A party rental company has chairs and tables for rent. The total cost to rent

Tema [17]

2c+5t=43

c=(43-5t)/2

8c+3t=36 and using c found above in this equation gives you:

4(43-5t)+3t=36

172-20t+3t=36

-17t=-136

t=8, and since c=(43-5t)/2

c=1.5

So a table costs $8.00 to rent and a chair costs $1.50
