Tabish Z.

I'm playing it on PlayStation 4, just cannot figure out how to take cover..? which key is it?

What market structure is best for product and/or process innovation and why among:

- Perfect Competition

- Monopolistic Competition

- Oligopoly

- Monopoly

it surely isn't perfect competition because all firms are price takers and all they change is the quantity produced.

thanks.

I'm trying to find the center point on a triangle in 3-dimensions and its does not lie on any convenient plane that i could eliminate one axis and solve in 2D. so i've co-ordinates for example:

A=(0,5.8,-3)

B=(0.2,6.2,-3)

C=(0,6.2,-2.7)

so all i need right now is to find the center of this triangle ABC.

thanks.

I have the Kinetic Energy equation..

E = (mv^2)/2

partial differentiation:

dE/dv = mv

I understand that it is the momentum

but I am not sure what would

dE/dm = v^2/2 would mean in common language..

How do I determine an equation is linear or not in variables x, y, and z. If they are or not, I need to explain why they are linear or why they are not.

for example: x^2 + y^2 + z^2 = 1

and

2x - xy - 5z = 0

can't figure out if they are linear or not, and if they are how.. please help thanks.

I bought a car with zero down payment on financing term of 5 years, now it is getting hard on me to pay the monthly instalments and insurance, and I may not need this expensive car anymore. I am only 20 months through out of 60 months term. What is the best way to get out of it in Canada.

I tried selling it, but of course it would be a loss for me, cause it would be sold for half of what I'm suppose to pay for it. is there a way to get out of i'm stuck for the rest 40 months?
