The half angle formula is:
sin x/2 = +/- √ (( 1-cos x ) / 2 )
5π/12 = 5π/6 : 2
sin 5π/12 = +/- √(( 1 - cos ( 5π/6)) / 2 )
cos 5π/6 = cos 150° = -√3/2
≈ 0.966 ( this is sin 5π/12 )
Answer:
B is 4 because there is no other one digit number that is a common multiple of 4
Step-by-step explanation:
Answer:
y = 2x + 3
Step-by-step explanation:
A line parallel to y = 2x has exactly the same slope but a different y-intercept, b.
Start with y = mx + b, and replace m with 2, y with -1 and x with -2:
-1 = 2(-2) + b, or
-1 = -4 + b.
Then b = 3, and the desired equation is y = 2x + 3
First, distribute 2/3 to the values in the parentheses. This gives you y-1=2/3x+6.
To get y alone, we add 1 to both sides. This gets you y=2/3x+7.
y=mx+b
y=2/3x+7
It matches the standard form, so your final answer would be y=2/3x+7.
Answer:
Hypothesis
Step-by-step explanation:
Hypothesis:
- It is an assumption or explanation that need to be tested.
- It determines the claim in the testing.
- There are two types of hypothesis: Null hypothesis and alternate hypothesis.
- Null hypothesis says that the sample is taken from the population.
- Alternate hypothesis states that the sample does not belong to the defined population.
A hypothesis is a testable claim or statement, that is yet to be tested, concerning the relationship among variables that can be observed.
