Answer:
Yes, no two ordered pairs in this list has the same second element.
Step-by-step explanation:
The function is a relation that associates to different elements 
and 
different elements 
and 
Given K = {(-3, -3), (-4, -4), (-5, -5), (-6, -6)}
So,
Since different x have different image points y, this relation is the function. The correct answer is "Yes, no two ordered pairs in this list has the same second element."
Answer: B. 12 and 64
Step-by-step explanation:
Option A is incorrect because the highest common factor for both numbers would be 38 not 4.
Option B:
Factors of 12 are: 1, 2 , 3, 4, 6, 12
Factors of 64 are: 1, 2, 4, 8, 16, 32 and 64.
<em>Highest factor of both is 4 and they both add up to 76 so option B must be correct. </em>
Answer:
The length of the missing side x = 47.57 in
Step-by-step explanation:
Given
Ф = 28°
The length of the side adjacent to the angle Ф is = 42 in
To determine
The hypotenuse x = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
substitute adjacent = 42 in, hypotenuse = x and Ф = 28°
cos 28° = 42 / x
x = 42 / cos 28°
x = 47.57 in
Therefore, the length of the missing side x = 47.57 in
