Answer:

Step-by-step explanation:
Here we gonna use the identity -

So using the identity here,

So, given a quadratic function, y = ax2<span> + bx + c, when "a" is positive, the </span>parabola<span> opens upward and the vertex is the </span>minimum<span> value. On the other hand, if "a" is negative, the graph opens </span>downward<span> and the vertex is the </span>maximum<span> value. To put it in complicated terms. Or when A is positive the graph is shaped like a U but if A is negative the graph is an upside down U

Answer:
hi there
40.3
Step-by-step explanation:
28547=100%
11504=R
11504 x 100=1150400/28504
1150400/28504=40.29 = 40.3
I dotn believe that a pair of angles can be vertical and supplementary. because vertical angles are across from each other, and supplementary angles are two angles next to each other (adjacent) that have a sum of 180. im not sure how to give an example/nonexample.
