PLEASE HELP i am desperate. Zack is building a model sailboat. The mast will have two inches of height below the base of the main sail, as shown in the diagram below. He wants the base of the sail to have a length of 11 inches and angle S to measure 49 degrees.
A) Write an equation that can be used to find the length of the side of the triangular sail opposite angle S.
B) Find the length of the side of the triangle opposite angle S, to the nearest tenth.
C) What will be the height of the mast, to the nearest tenth?

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.

The function v(r)=4/3pir^3 can be used to find the volume of air inside a basketball given its radius. what does v(r) represent
