An angle measures 84° less than the measure of its complementary angle. What is the measure of each angle?

the y coordinate of vertex is 9. It represents the maximum height .

Step-by-step explanation:

A baseball player hits a ball. The table represents a quadratic function that shows how the height of the ball changes over time.

Time (s) Height (ft)

0 5

0.25 8

0.50 9

0.75 8

1.00 5

1.25 0

To find the y coordinate of vertex, first we find the vertex point from the given table

after and before x=0.50 the value of y is 8 and it starts decreasing so the vertex point is (0.50,9)

the y coordinate of vertex is 9. It represents the maximum height .
