You decide that you want to take a walk to enjoy the nice afternoon weather. You leave your house and walk 20 m due east. Then in some unknown direction for some unknown distance. From this unknown position, to get back home, you find that you have to travel 8 m west and 10 m north. How far and in what direction did you walk for your second leg of your trip (the unknown leg)?

Drew wants to get back to his campsite on the beach as fast as possible. He is swimming at a point in the water that is 300 feet from the shore at its closest distance, and his campsite is 3000 feet down the (perfectly straight) shore from there. In order to minimize his time, he wants to swim to some point (x) on the shore and then run the remaining distance. (x = 0 means he’s swimming the 300 feet...

Let f(x,y) = 9y^2 −(3x^2)y denote the temperature at the point (x,y) in the plane, and let C(t) = (t^2, 3t) be the path of a crawling ant in the plane. Find how fast the temperature of the ant is changing at time t = 2. At time t = 2 the ant is at the point C(2) = (4, 6). Which direction should the ant crawl to warm up as quickly as possible (in the near term)? Please a...

Implicit derivative 1 Find y’(x) from F(x,y) =2^(-x -y) *ln(3*x +3*y) -x -y +(x+y)^3 =20 at (x,y)=(1, 1.824). Write y’(1) at this point as a number in decimal notation with at least two digits after the decimal point. No fractions, spaces or other symbols. Hint: the simple solution does not even require taking derivatives.

a. Draw the parabola y=x^2 and the point (0,3) in the square window -2 < x < 2 and 0 < y <4. b.    Fill in the four blanks to complete the formula giving the distance D from the point (0,3) to a general point (x,y) in the plane. D = Sqrt[( - )^2 + ( - )^2]   c. Find the points on the parabola y=x^2 which are closest to the point (0,3). You must have both appropriate calculations...
