Step-by-step explanation:
PQRS is a cyclic quadrilateral.
the opposite angles in a cyclic quadrilateral sum to 180° then
∠ Q + ∠ S = 180 ( substitute values )
3x - 8 + 3x + 8 = 180
6x = 180 ( divide both sides by 6 )
x = 30
Then
∠ Q = 3x - 8 = 3(30) - 8 = 90 - 8 = 82°
∠ S = 3x + 8 = 3(30) + 8 = 90 + 8 = 98°
∠ P = x + 15 = 30 + 15 = 45°
∠ R = 180° - ∠ P = 180° - 45° = 135°
Answer:
See below.
Step-by-step explanation:
Refer to the graph.
The range of a graph is the span of y-values it covers.
From the graph, we can see that the span of y-values is all values greater than or equal to 0.
Therefore, our range is, in interval notation:

Note that we use brackets with the 0 because 0 is included in our range.
In set notation, this is:
Answer:
Step-by-step explanation:
For the zeros, c is shows the correct number of zeros -- 7.
But you should note that the answer ought to contain the correct number of sig digs. There are 3. 692 The 2 cannot be dropped. Still your answer is correct.
Increasing: (-4,-4)
Decreasing: (4,-2)
