3. A firm’s total cost function is given by TC= 3X^2 + 2XY+7Y^2

Where X and Y denote the number of items of goods 1 and 2, respectively that are produced. Using the substitution method, find the values of X and Y which minimize costs if the firm is committed to producing 40 goods of either type in total.

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.

i believe it's a.

i'm not sure on this one, most likely correct.

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
