{(0, 1), (0, 5), (2, 6), (3, 3)} is not a function because zero is repeated in (0, 1),(0, 5)
While
{(1, 4), (2, 7), (3, 1), (5, 7)} is a function because there is no repetition in domain i.e. first element of each ordered pair is unique.
Step-by-step explanation:
To decide whether a relation is a function or not, the first elements of each ordered pair (domain) are observed. In order for a relation to be a function, there should be no repetition in first elements of each ordered pair.
In the given group of points:
{(0, 1), (0, 5), (2, 6), (3, 3)} is not a function because zero is repeated in (0, 1),(0, 5)
While
{(1, 4), (2, 7), (3, 1), (5, 7)} is a function because there is no repetition in domain i.e. first element of each ordered pair is unique.
The farthest distance on the planet that the eye can see is given by the formula
= your first height and =your second height
Since or the height of the periscope over the water and for the height of the ship the answer is 832.45553203368 feet, but because the question asks to the nearest mile the answer would be
If you get it wrong just tell me and I will rework my math again :-)
It is usually sufficient to try the values of a couple of points in the offered answer selections to see which one fits.
You have not provided any choices, so I have used the polynomial regression function of a graphing calculator to compute the cubic that will represent these ordered pairs exactly.
