Answer:
A turning point is the highest or lowest point on a quadratic graph.
Step-by-step explanation:
A quadratic graph looks something like the graph below.
The equation of a quadratic graph would normally look like
+/- ax^2 + bx + c
An example might be -16x^2 + 5x + 4
Note the negative symbol in front of the 16. The negative means that the graph will be facing downwards, or that the turning point is the highest point. A positive graph will mean that the graph is facing upwards, or that the turning point is the lowest point.
Essentially, it is the location where a graph has its lowest or highest point and where the y-values (can include x-values in horizontal quadratics) "turn" to the direction they originated.
Answer:
1/8
Step-by-step explanation:
1/2 divided by 4
1/2 x 1/4 = 1/8 for each
Answer:
The measure of the angles would be 40.1 degrees and 49.9 degrees.
Step-by-step explanation:
Complementary angles add up to 90 degrees together.
90 - 9.8 = 80.2
80.2 / 2 = 40.1
Angle 1 = 40.1
Angle 2 = 40.1 + 9.8 = 49.9
Check:
40.1 + 49.9 = 90
