In evaluating a double integral over a region D, a sum of iterated integrals was obtained as follows: ∬Df(x, y)dA=∫40∫(1/2)y0f(x, y)dxdy+∫64∫6−y0f(x, y)dxdy. Sketch the region D and express the double integral as an iterated integral with reversed order of integration. ∫ba∫g2(x)g1(x)f(x, y)dydx

The length of a shadow of the building is 36m. the length of the pole, which is perpendicular to the ground, is 1.9m. the length of the pole's shadow is 1.52m. what is the height of the building?

Answer this two poles, ab and ed, are fixed to the ground with the of ropes ac and ec, as shown: two right triangles abc and edc have a common vertex c. angle abc and edc are right angles. ab is labeled 13 feet, ac is labeled 15 feet, ec is labeled 10 feet, and ed is labeled 4 feet.what is the approximate distance, in feet, between the two poles? 11.14 feet16.65 feet14.35 feet15.59 feet
