Answer:
Constant
Step-by-step explanation:
(1,32)
(2,64)
(3,96)
They increase by 32 each time
Answer:
Nope
Step-by-step explanation:
Since they both have different variables they aren’t like terms
27/36 = n/4
27*4 = 36n
108 = 36n
108/36 = 36n/36
n = 3
Answer:
21 19/25
Step-by-step explanation:
21 76/100
divide 76 and 100 by 4
21 19/25
The value of the given trigonometry function is 2√15/15
<h3>Half angles</h3>
Half angles are trigonometric identities used to express sine, cosine and tangent of half angles.
For instance the value of cos theta is expressed as shown below;
cosФ = cos(Ф/2+Ф/2)
cosФ = cos²Ф/2-sin²Ф/2
cosФ = cos²Ф/2-(1-cos²Ф/2)
cosФ = 1 - 2cos²Ф/2
Given the following parameters
cosФ = -7/15
Substitute
cosФ = 1 - 2cos²Ф/2
-7/15 = 1 - 2cos²Ф/2
-2cos²Ф/2 = -7/15 - 1
-2cos²Ф/2 = -8/15
cos²Ф/2 = 4/15
cosФ/2 = 2/√15
Rationalize
2/√15 * √15/√15
2√15/15
Hence the value of the given trigonometry function is 2√15/15
