3. 1/5 4. 13/20 pretty easy if you think about it
Answer:
8.6615988
Step-by-step explanation:
f(x) = 3 sin (x) / ( 1 + cos x)
To find the derivative bottom * d/ dx top - top d/dx bottom all over the bottom squared
d/dx = 3 ( ( 1 + cos x) cos x - sin x( - sin x)) / ( 1 + cos x) ^2
= 3 ( cos x + cos ^2 x + sin ^2 x) / ( 1 + cos x) ^2
= 3 ( 1 + cos x) / ( 1 + cos x) ^2
= 3 / ( 1 + cos x)
Let x = 4
3 / ( 1 + cos 4)
Assuming x is in radians

Answer:
A
Step-by-step explanation:
We know it cant be -6 as that would be a range and since the circle on the end is hallow it wont be less or equal to rather just less than and the since the next one is 2 and its solid circle it has to be less than or equal too

Step-by-step explanation:
To evaluate f(g(x)) substitute x = g(x) into f(x)
f(g(x))
= f(3x - 4)
= 2(3x - 4) + 1
= 6x - 8 + 1
= 6x - 7
---------------------------------------------
To evaluate g(f(x)) substitute x = f(x) into g(x)
g(f(x))
= g(2x + 1)
= 3(2x + 1) - 4
= 6x + 3 - 4
= 6x - 1
