Sketching Graphs of Quadratic Functions in Context - Item 33107 Elliot makes and sells key chains. His profit depends on what price he charges for a
key chain
He writes the expression (x – 10)(60 – 3x) to represent his profit based on the
price per key chain, r.
Enter Elliot's average change in profit for two different sections of the graph.

Write a corresponding real world problem to represent 2x - 125=400

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?

Cor d? ? me ? max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
