From the graph of a quadratic equation, you can find:
The roots. These are the points where the graph crosses the x-axis, and is the solution of the quadratic equation when y=0. Usually, there are either two or zero.
The coefficient of the leading term. In the quadratic equation y= ax^2 + bx + c,
the parabola points upward if a is positive, and downward if a is negative.
The vertex. You can find the vertex, or where the two sides of the parabola meet, by looking at the graph.
You would divide 245 by 49 to get a
a= 5
1 lb = 16 oz
Translating the unit into oz gives us
166oz - 123oz = 43oz or 2lb 11oz
190. Count it out on your fingers, starting with -10,-15, and -20. Then count out both hands.
Batting average= hits/bats
280 or more= hits/522
Hits = 522• 280 = 146,160 or more
