Answer:
yes it is a function D
Step-by-step explanation:
When you draw a vertical line through any part of the parabola, you will see that it will only intersect with one point.
B is not the answer because it would not matter if there are no y values that have more than one x value becuase the statement that matters is...
each x value should have 1 and ONLY one output (or y-value)
The equation we can use to find the value of x in the diagram given is: B. (5x + 30) + 5x = 90.
<h3>What are Complementary Angles?</h3>
Angles that give a sum of 90 degrees when added are referred to as complementary angles.
The angles, (5x + 30) and 5x are complementary angles, since the sum of both gives a right angle (90 degrees).
Therefore, the equation that we can use to find x in the diagram is: B. (5x + 30) + 5x = 90.

Answer:
C.
Step-by-step explanation:
symmetry means that when you fold the paper along the line of symmetry shape is overlapping
Answer: 15x+30
Step-by-step explanation:
Step-by-step explanation:
cot(x) cos(x) + cot(x) = 0
cot(x) (cos(x) + 1) = 0
cot(x) = 0 or cos(x) = -1
cot(x) = 0
x = π/2, 3π/2
x ≠ 0, π
cos(x) = -1
x = π
Therefore, the answer is x = π/2, 3π/2.
