The vertex of a parabola is the point where the parabola crosses its axis of symmetry. Therefore, the coordinates of the vertex is (2,4).
I believe it is asking you to state if there’s any correlation between science and math test scores based on the graph.
Hope this helps!
75°
The angles adjacent to A and B are 180° - 105° = 75°
These adjacent angles are the other alternate interior angles
Similar triangles have a scale factor that determine the length of each side.
15 / 7.5 = 2
The scale factor = 2
17 / 2 = 8.5
y = 8.5
You use the Pythagorean theorem which is a^2+b^2=c^2
So....
.8^2+.6^2=c^2
.64+.36=c^2
1=c^2
1=c becaaue the square root of one is one
