Let f(x, y)=x2ex2 and let r be the triangle bounded by the lines x=2, x=y/2, and y=x in the xy-plane. (a) express ∫rfda as a double integral in two different ways by filling in the values for the integrals below. (for one of these it will be necessary to write the double integral as a sum of two integrals, as indicated; for the other, it can be written as a single integral.)

step-by-2step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.
