Problema Solution
Anthony and Sanford each throw a football. The height of Anthony's throw can represented by the equation A = –10x2 + 15x + 22, where A is height and x is the time in seconds. The height of Sanford's throw can represented by the equation S = –9x2 + 14x + 23. At time x, what is the combined height of the throws?
Answer provided by our tutors
A + S = (–10x2 + 15x + 22) + (–9x2 + 14x + 23) = -19x^2 + 29x + 45
