Step-by-step explanation:
<h3>Axis of symmetry: </h3>
Axis of symmetry is the vertical line that divides the parabola into two equal halves and it passes through the vertex of the parabola.
From the graph, Vertex (-3, 4)
Axis of symmetry: x = -3
Answer:
P(A) = 3/10
P(B) = 7/30
P(A and B) = 2/15
P(A/B) = 4/7
No P(A/B) ≠ P(A)
No, events A and B are not independent events.
Answer:
<h2>C. </h2>
Step-by-step explanation:
We have the parabolas:
(1) y = x² + 2 and (2) y = x² - 6
The common shaded region is below parabola (1) and above parabola (2).
Therefore y < x² + 2 and y > x² - 6
Using trigonometry table :
Sine 0 = 0
Cosine 0 = 1
Tangent 0 = 0
Co-secant 0 = 1/sine 0
= 1/0
= undefined
Secant 0 = 1/cos 0
= 1/1
= 1
Cotangent 0 = 1/tan 0
= 1/0
= undefined<span />
