You jump off the 10-foot diving board at the local pool. You bounce up at 6 feet per
second and then drop toward the water. Your height h (in feet) above the water at
time t (in seconds) can be modeled by the function
h(t)=−16t^2+6t+10
1. Graph this function, with t on the horizontal axis. Construct a table of values
where the increments of time are tenths of a second.
2. Find the domain and range of the function. Explain your reasoning.
3. Explain why this situation is quadratic instead of linear. Give a graphical
explanation and a logical explanation.
4. Use the graph to determine the maximum height of your dive.
5. Use the graph to determine when you reach the maximum height of your dive.
6. Use the graph to determine how long it takes you to hit the water.
7. Use the Quadratic Formula to verify your answer in Exercise 6.

Needmax 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.

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
