The coordinates of points a and b are a (7, -2) and b (47, 68). which are the coordinates of a point that partitions segment ab in a ratio of 1: 4?

Aheated piece of metal cools according to the function c(x) = (.5)x ? 7, where x is measured in hours. a device is added that aids in cooling according to the function h(x) = ? x ? 2. what will be the temperature of the metal after two hours?

Which value would be a solution for x in the inequality 47-4x< 7

Sketch the region enclosed by the given curves. decide whether to integrate with respect to x or y. draw a typical approximating rectangle and label its height and width. y= 5x, y=7x^2then find the area s of the region.
