Use the Pythagorean theorem:

The length of the hypotenuse is approximately 14.1 in.
Z=5.714285714285714 because you subtract 0.3z from 0.02z which = 0.28z and then subtract.2 from 1.8 which is 1.6. So then divide 1.6 by 0.28 to find z.
The answer to number 17 is c

Answer:
(1, 4) and (1,3), because they have the same x-value
Step-by-step explanation:
For a relation to be regarded as a function, there should be no two y-values assigned to an x-value. However, two different x-values can have the same y-values.
In the relation given in the equation, the ordered pairs (1,4) and (1,3), prevent the relation from being a function because, two y-values were assigned to the same x-value. x = 1, is having y = 4, and 3 respectively.
Therefore, the relation is not a function anymore if both ordered pairs are included.
<em>The ordered pairs which make the relation not to be a function are: "(1, 4) and (1,3), because they have the same x-value".</em>
