1. Let f(x,y) = 3$x^{2} $ -10xy+3$y^{2} $ on the region [0,4] x [0,4]; evaluate the double integral 2. Change the region to 0 < x < 3 and 0 < y < $\sqrt{9-x^2}$ ; evaluate the double integ...

What is f(x)? I've gotten so many different answers , let's say f(x)=x²+15x+50, now I was told before that that means we have a function called f, when we inputted x into it f squared it then added 15...

1. 2. Can someone help with these two, the answers i solved, i dont know if it is correct. Thank you

Need this simple business calculus problem solved with a reason why it is true or false. Give a more simple solution if possible. Thank you 

Must show all work, this is for a discussion board which I have to show full work to receive points.

I was given the following exercise during an exam:A company produces two kinds of products with number of x and y pieces. They can sell the first product at a unit price p = 300 - 3x USD and the secon...

Calculate the derivative of this function

I understand that when we write e = lim⁡ n→∞ (1+1/n)^n, we are identifying the number that this expression converges to as n becomes very large. However, I also know that lim⁡ n→∞(1/n)= lim⁡ n→∞(100/n...
