Aman finds himself on a riverbank with a cat, a parrot and a bag of seed. he needs to transport all three to the other side of the river in his boat. however, the boat has room for only the man himself and one other item (either the cat, parrot or seed). in his absence, the cat could eat the parrot, and the parrot would eat the bag of seed. show how he can get all the passengers to the other side, without leaving the wrong ones alone together.

To find the extreme values of a function f(x. y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x, y)=xy

Solve for x in the equation x2 - 12x + 36 = 90. x= 6+3x/10 x=6+2/7 x= 12+3/22 x = 12+3/10

What is the equation of a line that passes through points (0, 4) and (-4,-8)?
