Flying against the wind, an airplane travels 8280 kilometers in 9 hours. Flying with the wind, the same plane travels 3900 kilometers in 3 hours. what is the rate of the plane in still and what is the rate of the wind?
rate of wind=?
rate of plane in still air=?

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
