This is the equation of a vertical parabola open downward
The vertex is the point (3.25,225) (a maximum)
The zero's of the function or the t-intercepts are the points (-0.5,0) and (7,0)
The h-intercept of the function is the point (0,56)
The domain of the function are all real numbers
The range of the function
----> All real numbers less than or equal to 225

Answer:
a)No
Step-by-step explanation:
2x - 8x = -6x instead of 10x.
So it shoukd be -6x - 3 = 33
We use the law of Cosines to be able to find : 1. The measure of the
third side, when the measure of two sides and the included angle of a
triangle ABC are known. 2. The measure of any angle, when the measure of
the three sides of a triangle ABC are known.
The Law of Cosines is c² = a² + b² - 2abcosΘ. It has four variables;
a, b, c and Θ. Whenever you have a triangle with three of these
variables known, use the Law of Cosines to calculate the unknown
variable.
