Find an equation for the contour of f(x, y)=2x2y+7x+20f(x, y)=2x2y+7x+20 that goes through the point (3,−2)(3,−2).

A contour at height c have as its equation

The equation of the contour is

The given parameters are:

Recall that:

Substitute in f(x,y)

Evaluate exponents

Evaluate the products

Replace 3 and -2, with x and y

Substitute 5 for f(x,y) in

Collect like terms

Hence, the equation of contour is

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
