Answer:
Therefore, the solutions of the quadratic equations are:

The graph is also attached.
Step-by-step explanation:
The solution of the graph could be obtained by finding the x-intercept.

Finding the x-intercept by substituting the value y = 0
so

∵ y = 0












So, when y = 0, then x values are 3, and 5.
Therefore, the solutions of the quadratic equations are:

The graph is also attached. As the graph is a Parabola. It is visible from the graph that the values of y = 0 at x = 5 and x = 3. As the graph is a Parabola.
It would be: 213500 * 18/100
213500 * 0.18 = $38430
So, option D is your answer.
Hope this helps!
7 = r^1/2 is the same as saying 7 = square root of r. So, to get rid of the square root sign on the r, you need to square it, and when you do something to one side of the equation, you have to do the same to the other side. So after squaring both sides, you get 49 = r.
