Answer: B. 2=3x+10x^2
Step-by-step explanation:
The expression means the quadratic function equation.
B = 10x^2 + 3x -2 = 0
the equation is [-b ±√(b^2 -4ac)]/2a
b should be +3 to become -3 when it is plugged into the equation, and 'a' should be 10, and c should be -2.
The maximum of this parabola is (3/4,16).
Therefore since time is on the x-axis, the ball reaches the maximum height at 3/4secs.
And since the height is on the y-axis, the ball will each a maximum height of 16ft.
The answer is -18 because 15 + 3 is 18 and that is then turned negative
