To find where on the hill the canonball lands
So 0.15x = 2 + 0.12x - 0.002x^2
Taking the LHS expression to the right and rearranging we have -0.002x^2 + 0.12x -
0.15x + 2 = 0.
So we have -0.002x^2 - 0.03x + 2 = 0
I'll multiply through by -1 so we have
0.002x^2 + 0.03x -2 = 0.
This is a quadratic eqn with two solutions x1 = 25 and x2 = -40 since x cannot be negative x = 25. The second solution y = 0.15 * 25 = 3.75

Answer:
336
Step-by-step explanation:
area = 1/2 * (a + b) * h
2*3/8
whenever dividing the second fraction flips
2*3/8
You can divide by 2 for 2 and 8
2/2=1
8/2=4
1/4*3
=3/4
Answer is 3/4
