A football is thrown upward with an initial velocity of 50 feet per second from a height of 100 feet. The height of the object t seconds after it is thrown is glven by the function h(t) = -16t2 + 50t + 100. Determine the ball's average velocity from t = 0 to t = 3 seconds.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

Where’s the graph too show me?
