Applying the concept:
The measure of one of the central angles of a regular octagon.
The octagon have 8 sides, using the above formula we get...
Conclusion:
The correct option is <em><u>A) 45 degrees</u></em>
Answer:
Your answer of option b is right.
Step-by-step explanation:
Given that a sinesoidal function has maximum 12 and minimum -6
Hence centre line would be average of these two.
Centre line is
i.e. f(x) = a sin (bx+c)+3
Since amplitude = 12-3 =9 we have a = 9
i.e. f(x) = 9 sin (bx+c)+3
Frequency is given as 3, period = 1/3
This gives b = 6pi
f(0) = y intercept =
9sin(c)+3 =3
This gives c=0
Hence correct equation is
Answer:
1, , .
Step-by-step explanation:
probability =
Total number of persons in the party = n
a) Pr ( every person gets their phone back) = Pr (each person picks his phone ) multiplied by number of person
= × n = 1.
No of first m persons to pick = m
No of last m persons to pick = 1 - m
b) Pr (first m persons to pick each gets their phones back) =
c) Pr( first m persons get a phone belonging to last m persons) =
