Question 175155This question is from textbook
: In 1940, Emanual Zacchini of Italy was fired record distance of 175 feet from a cannon while performing in the untied states. Suppose his intial upward velocity was 80 feet per second. The height y can be represented by the function y=80x-16x^2, where x represents the number of seconds that have passed.
a) Draw the graph of the function, relating heights Mr. Zacchini reaches to the time after he was shot from the cannon.
b) How long after he was shot out of the cannon did he reach his maximum height? What was the height? This question is from textbook

a) Draw the graph of the function, relating heights Mr. Zacchini reaches to the time after he was shot from the cannon.
------------------------------------------------------------
b) How long after he was shot out of the cannon did he reach his maximum height?
maximum occurs at x = -b/2a = -80/-32 = 2.5 seconds
-------------
What was the height?
h(2.5) = 80*2.5 - 16(2.5)^2 = 100 ft.

You can put this solution on YOUR website! I cannot improve one bit on Stan's solution. However, I am curious -- Where in the world is the Untied States?
