Answer:
34
Explanation:
When 68 is decreased by 50%, that would mean that it is decreasing by half of that number. Half of that number would be 34 and that would be your answer.
I believe that the answer is 70. I hope I helped! The reason I say this is because BD is half of AE and 35+35=70 :)
The equation of the parabola as described in the task content is; f (x) = -3 (x - 5)² + 9.
<h3>What is the equation of the parabola as described in the task content?</h3>
It follows from the task content that the equation of the parabola which has the same shape as f(x)=-3 x² but with vertex (5,9) in the form f (x) = a (x-h)² + k be determined.
Recall that the vertex of a quadratic equations of the given form is defined by the coordinates (h, k).
On this note, the required equation of the parabola by substitution of h and k is;
f (x) = -3 (x - 5)² + 9.
