Answer:
The answer to your question is AD = 74
Step-by-step explanation:
Data
AB = CD = 10
BC = DE = 54
DE = 54
CD = 10
Process
From the picture we know that
AD = AB + BC + CD
Substitution
AD = 10 + 54 + 10
Simplification and result
AD = 74
Our parabola open downward and therefore a is negative.
Explanation:
As value of a changes from positive to negative or from negative to positive, the direction of opening changes. For negative values of a we got negative parabolas that open downward. As the original formula y = x^2 we see that x^2 will always be positive because when you square a number it always gives positive value. Therefore the direction for which it will open, depends on value of a.
