Find the absolute maximum and minimum of f(x,y)=5x+5y with the
domain x^2+y^2 less than or equal to 2^2
Suppose that f(x,y) = x^2−xy+y^2−2x+2y with
D={(x,y)∣0≤y≤x≤2}
The critical point of f(x,y)restricted to the boundary of D,
not at a corner point, is at (a,b)(. Then a=
and b=
Absolute minimum of f(x,y)
is
and absolute maximum is .

The cumulative distribution function for a random variable X is
F(x)= 0 if x less than or equal 0, or F(x)=sinx if 0 is less than x
is less than or equal to pi/2 , or F(x)= 1, if x is greater than
pi/2 . (a) find P(0.1 less than X less than 0.2. (b) find E(x)

A rectangular box is placed in the "octant" x,y,z is less than
or equal to 0, with one corner at the origin, the three adjacent
faces in the coordinate planes, and the opposite point constrained
to lie on the paraboloid: 10x + y2 + z2 =
