Answer:
Step-by-step explanation:
The given functions are:
and
Now,
The domain refers to values of for which is defined.
The expression under the radical sign must not be negative.
The domain is
If you are given with all the tree sides of the triangle, you may solve for all the angles through the Law of Cosines,
c² = a² + b² - 2ab(cos C)
where angle C is the angle opposite the side c. You may use the same equation to get the values of the remaining angle. Additionally, if you already have one known angle, you can solve for the rest of the angles by Law of Sines,
a / sin A = b / sin B = c / sin C
Answer:
(8, 20)
Step-by-step explanation:
Let's input each values of the ordered pair given as options to see which one satisfy the equation y = 16 + 0.5x
==>Option 1: (0, 18)
18 = 16 + 0.5(0)
18 = 16 + 0
18 ≠ 0
Option 1 is incorrect.
==>Option 2: (5, 19.5)
19.5 = 16 + 0.5(5)
19.5 = 16 + 2.5
19.5 ≠ 18.5
Incorrect.
==>Option 3: (8, 20)
20 = 16 + 0.5(8)
20 = 16 + 4
20 = 20
CORRECT
==>Option 4: (10, 21.5)
21.5 = 16 + 0.5(10)
21.5 = 16 + 5
21.5 ≠ 21
Incorrect.
The answer is (8, 20)
