**Problem Statement:****c.** When does the stone hit the river? Use the quadratic formula to solve.**Explanation:**To solve this problem, one needs to find the time at which the stone reaches the river. This involves using the quadratic formula, which is typically employed to find the roots of a quadratic equation of the form $ax^2 + bx + c = 0$. The quadratic formula is:\[x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{2a}\]Here, $a$, $b$, and $c$ are coefficients of the quadratic equation derived from the motion equation of the stone, typically involving variables such as initial velocity, height, acceleration due to gravity, etc. Solving this equation will provide the time(s) at which the stone reaches the ground level (or the river, in this context). 4. A stone is thrown into the air from a bridge over a river. The stone falls into the river. The height $ h $ above the river, of the stone in meters, $ t $ seconds after it is thrown is given by: \[ h = -12.3t^2 + 7.5t + 22.1 \]

Here, the height of the stone above the river is given by, h=-12.3t2+7.5t+22.1 When the stone will…
