An Olympic diver is competing for a medal. His height in feet above the water can be modeled by the function f(x) = -3x + 6x + 24, where x is the time in seconds after he begins the dive. Graph the function. Then find how long it takes the diver to reach the water.​

Just tell me how to set up the equation.

What is the total surface area of this square pyramid?

Abby is collecting rainfall data. she finds that one value of the data set is a high-value outlier. which statement must be true? abby will use a different formula for calculating the standard deviation. the outlier will increase the standard deviation of the data set. the spread of the graph of the data will not change. abby will not use the mean when calculating the standard deviation.
