Answer:
The period of given function is ![Period = 16\pi](https://tex.z-dn.net/?f=Period%20%3D%2016%5Cpi%20)
So, Option B is correct.
Step-by-step explanation:
In this question we need to find the period of the function y= 3 sin x/8
The formula used to find period of function is: ![\frac{2\pi }{b}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Cpi%20%7D%7Bb%7D)
We need to know the value of b.
To find the value of b we compare the standard equation with the equation of function given.
Standard Equation: y = a sin(bx - c) +d
Given Equation: y= 3 sin(x/8)
Comparing we get:
a= 3
b= 1/8
c= 0
d=0
So, we get the value of b i.e 1/8. Putting it in the formula to find period of given function.
![Period = \frac{2\pi }{b}](https://tex.z-dn.net/?f=Period%20%3D%20%5Cfrac%7B2%5Cpi%20%7D%7Bb%7D)
![Period = \frac{2\pi }{\frac{1}{8}}](https://tex.z-dn.net/?f=Period%20%3D%20%5Cfrac%7B2%5Cpi%20%7D%7B%5Cfrac%7B1%7D%7B8%7D%7D)
Solving,
![Period = 2\pi *8](https://tex.z-dn.net/?f=Period%20%3D%202%5Cpi%20%2A8)
![Period = 16\pi](https://tex.z-dn.net/?f=Period%20%3D%2016%5Cpi%20)
So, the period of given function is ![Period = 16\pi](https://tex.z-dn.net/?f=Period%20%3D%2016%5Cpi%20)
It is b i think hope this helps
It could be 42÷30=1.4 and 42×30=1,260 and 42-30=12 and 42+30=72
Given:
Two cubes are rolled together.
To find the probability that the sum of the numbers on the number cubes will equal 4.
Formula
P(A) = ![\frac{x}{y}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D)
where, A be any event.
x be the number of successful outcomes
y be the total number of outcomes
Now,
If the two cubes are rolled together, total number of outcomes = 36
In total outcomes, the sum of the numbers of cube will be 4 for (1,3),(3,1) and (2,2)
So, the number of successful outcomes = 3
Now,
Putting x=3 and y = 36 we get,
![P(A) = \frac{3}{36}](https://tex.z-dn.net/?f=P%28A%29%20%3D%20%5Cfrac%7B3%7D%7B36%7D)
or, ![P(A) = \frac{1}{12}](https://tex.z-dn.net/?f=P%28A%29%20%3D%20%5Cfrac%7B1%7D%7B12%7D)
Hence,
The probability that the sum of the numbers on the number cubes will equal 4 is
. Option D.
