Answer:
55°
Step-by-step explanation:
![m\angle C = \frac{1}{2} (184 \degree - 74 \degree) \\ \\ \implies \: m\angle C = \frac{1}{2} (110 \degree) \\ \\ \implies \: m\angle C = 55 \degree](https://tex.z-dn.net/?f=m%5Cangle%20C%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%28184%20%5Cdegree%20-%2074%20%5Cdegree%29%20%5C%5C%20%20%5C%5C%20%20%5Cimplies%20%5C%3A%20m%5Cangle%20C%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%28110%20%5Cdegree%29%20%5C%5C%20%20%5C%5C%20%20%5Cimplies%20%5C%3A%20m%5Cangle%20C%20%3D%20%2055%20%5Cdegree)
Answer:
It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant.
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.
