If you are dividing it will become 1 because 10 minus 10 equals 0. Anything to the power of 0 is 1 then you keep the base which is y so the answer is y
If you are multipling the answer will be y^10 because 10 plus 10 is 20 and you keep the base which is y
Since density is the ratio of mass to (in this case) area, we can find the mass of the triangular region by computing the double integral of the density function over :
The boundary of is determined by a set of lines in the plane. One way to describe the region is by the set of points,
