A lamina in the xy−plane occupies the region that is bounded by the curves 21yx=−, 29yx=−, 3yx=, and yx=−. (This means that each of the four listed curves forms a part of the boundary.) a) Sketchtheregion in the xy−plane. Label the boundary curves and shadethe region.b) Suppose that the mass density of the lamina at each point is proportionalto the square of its y−coordinate. Write a formula for the mass density function and include its units, supposing that mass is measured in kg and distance is measured in meters.c) Express the total mass of the lamina as an iterated double integral expression using Cartesian (rectangular) coordinates, with integration with respect to yfirst.d) Convert the double integral in (c) to polar coordinates andevaluate to find the total mass of the lamina.

0.86 degrees league ballpark in which the distance from home plate to the center field fence and the height of the center field fence require that a ball hit 2 ft above the ground will necessitate an angle of elevation less than 0.86 degrees to just clear the center field fence.
