The quadratic function h=-0.01x^2+1.18x+2 models the height of a punted football. the horizontal distance in feet from the point of impact with the kickers foot is x, and h is the height of the ball in feet.

a. write the function in vertex form. what is the maximum height of the punt?

b. the nearest defensive player is 5ft horizontally from the point of impact. how high must the player reach to block the punt?

c. suppose the ball was not blocked but continued on its path. how far down the field would the ball go before it hit the ground?

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
