Answer:
The answer is 204 square cm.
Step-by-step explanation:
You are asking for the surface area, and while calculating the surface area you will multiply the quantities.
Surface Areas: 17 cm multiply 12 cm
17 X 12 = 204
The answer is 204 sq. cm
The given parabola will open; Down
<h3>How to interpret a parabola curve?</h3>
In parabolic curves, if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.
Now, we are given the equation of the parabola s;
-36y = x²
divide both sides by -36 to get;
y = -x²/36
From the above it is clear that the leading coefficient is less than zero and as such the parabola will open in the downward direction.

Use the discrimant to determine the nature of the roots
Here's the formula of the discriminant from the equation ax²+bx+c = 0
D = b² - 4ac
If the discriminant is greater than 0, the quadratic equation has 2 real different roots
If the discriminant is equal to 0, the quadratic equation has only one real root.
If the discriminant is less than 0, the quadratic equation doesn't have real root.
Find the discriminant of the equation x² - 2x + 1 = 0
D = b² - 4ac
D = (-2)² - 4(1)(1)
D = 4 - 4
D = 0
The equation has only one real root.
