Which statement correctly explains whether the equation y = x2 – 2 represents a function? It is a function because there is only one x-value for each y-value.
It is not a function because there are no y-values less than – 2.
It is not a function because y = 2 when z = 2 or x = -2.
O It is a function because there is only one y-value for each 2-value.

In the diagram below what is the approximate length of the minor arc ab

Aball is dropped from a height of 10m above the ground. it bounce to 90% of its previous height on each bounce. what is the approximate height that the ball bounce to the fourth bounce?

Answer this two poles, ab and ed, are fixed to the ground with the of ropes ac and ec, as shown: two right triangles abc and edc have a common vertex c. angle abc and edc are right angles. ab is labeled 13 feet, ac is labeled 15 feet, ec is labeled 10 feet, and ed is labeled 4 feet.what is the approximate distance, in feet, between the two poles? 11.14 feet16.65 feet14.35 feet15.59 feet
