 Question 150652: How do you completly factor a problem like x^2 + 10x + 21, what's the answer for it? Click here to see answer by jim_thompson5910(29613)

 Question 150685: The path of a falling object is given by using the function s= -16t^2+ v sub0 t+ s sub0 where v sub0 represents the initial height in ft/sec and s sub0 represents the initial height in feet. Also, s represents the height in feet of the object at any time, t which is measured in seconds. A. If a rock is thrown upward with an initial velocity of 40 feet per second from the top of a 30 foot building, write the height (s) equation using this information... I got.. -16t^2 + 40t + 30 B.How high is the rock after 2 seconds? I got.. s(t)= -16(2)^2 + 40(2) + 30 s(t)= 46 C. After how many seconds will the graph reach maximum height? Show work algebraically. D What is the maximum height? I need help on C and D... and please tell me if I have figured A and B correctly... Thank you so very much. Click here to see answer by jim_thompson5910(29613)
