The answer in exact form is 27/28 but in decimal form it is 0.96
Answer:
2sin2(x). cos( x)
Step-by-step explanation:
As per the trigonometric identities sin3(x)= 3sin(x) - 4sin^3 (x)
putting this in the given expression
sin3x +sinx = 3sin(x) - 4sin^3 (x)+ sinx
= 4sinx - 4sin^3 (x)
= 4sinx(1 - sin^2 (x))
As per the trigonometric identities cos^2(x) = 1-sin^2 (x)
putting this in the above expression
= 4sinxcos^2 (x)
= 2cos(x) (2sin(x)cos(x))
As per the trigonometric identities 2sinx.cosx = sin2(x)
putting this in the above expression
= 2cosx sin2(x)
=2sin2(x). cos( x)

Answer:
It would be the first one
Step-by-step explanation:
because there are 3 positive and 2 negative
1+3x = 4x-9
add 9 to each side: 10+3x = 4x
subtract 3x from each side: 10 = x
7+2x = 3x
subtract 2x from each side: 7 = x
By looking at this data, you can see that while most of the data is in between 70 and 73, the only number that isn't in that range is 78. Therefore, the term outlier describes 78in the best.
