Step-by-step explanation:
Solution,
No. of people who participated= 20
No. of people who didn't participated= 15
Total number of people= 20+15= 35
Now,
Percentage of people who didn't participated
=No. of people who didn't participated/Total number of people×100%
=15/35×100%
=42.86%
Again,
Percentage of people who participated
participated=No. of people who participated/Total number of people×100%
=20/35×100%
=57.14%
Answer:
x = ⅓ acos(y/7) + π/18, [-7, 7/2]
Step-by-step explanation:
y = 7 cos(3x − π/6)
Solving for x:
y/7 = cos(3x − π/6)
acos(y/7) = 3x − π/6
acos(y/7) + π/6 = 3x
x = ⅓ acos(y/7) + π/18
The domain of x is the same as the range of y.
When x = π/6:
y = 7 cos(3π/6 − π/6)
y = 7 cos(π/3)
y = 7/2
When x = 7π/18:
y = 7 cos(21π/18 − π/6)
y = 7 cos(π)
y = -7
So the domain of x as a function of y is [-7, 7/2].
So if 2 is the first term then if n=1 then n+1=sequence so far but
second term is 9 so if n=2 then the 2nd term=9
you must use trial and error to find
so it is
7n-5 so if n=1 then
7(1)-5=7-5=2
if n=2 then
7(2)-5=14-5=9
sucess
the equation is 7n-5
The answer is b the two equations are equal to each other
