Area of ellipse - Study guides, Class notes & Summaries

Area and Similar Figures In two similar triangles, the ratio of their areas is the square of the ratio of their sides. Trigonometry Identities sin²(t) + cos²(t) = 1 Functional Definition, Notation, and Interpretation In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. Given f(x) = x² + 2x - 1, find f(2). f(2) = (2)² +2(2) - 1 = 4 + 4 - 1 = 7 Circles and O...

A mass of broken rock high on a mountain slope has a rectangular area measuring 400m and 600m, and is 50m thick. Mass fails and slides down the mountain. The final density of the failed mass does not change but is now distributed uniformly over an elliptical area of 800m download and 500m across the slope. What is the average depth of the runout mass of broken rock. a) 38m b) 9.5m c) 72m d) 30m e) 50m ~ a mass rectangle = mass ellipse 400 x 600 x 50 = π x (800/2)(500/2)T T = 38...
