An object is launched upwards at 29 feet per second from a height of 96 feet. The height of the object t seconds after launch is given by s(t)=-16t^2+29t+96. Find the velocity of the object in feet per second when it strikes the ground. Round the decimal to two decimal places.

The sum of two numbers is 86, and their difference is 20. find the two numbers

What is the ratio of the length of an object in yards to the length of the same object in miles?

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.
