Question

HELPPP!!
a object tossed into the air with an upward velocity of 22 ft/s will rise and fall according to the equation s=22t – 16t^2 . at what time is the object at maximum height?

Answer 1

are you familiar with the first derivative?

Answer 2

no

Answer 3

are you familiar with finding the vertex of a parabola?

Answer 4

kind of

Answer 5

x= -b/2a

Answer 6

y= f(x)

Answer 7

ok...

Answer 8

@annalizz12 is this from calculus?

Answer 9

if not, then use the vertex. if it is then find the derivative and set it equal to 0, you will get the same answer both ways, but your teacher might want a certain method.
