The formula to determine the circumference is: 2 x 3.14 x radius. All you need to do is plug in the value of the radius, 56, and multiply it by 2 and 3.14.
You can formulate an equation of the line given two points using the two-point slope form:
m = (y2-y1) / (x2-x1)
Wherein, after plugging in the values, it will now be on the form:
y = mx + b
I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:
2
Step-by-step explanation:
(derivative of cos(x) is -sin(x))
[cos²x is same as (cosx)²]
f'(x) = 4(cos(4-3x))³ (-sin(4-3x)) (-3)
f'(x) = -12 (cos(4-3x))³(-sin(4-3x))
f'(x) = 12 cos³(4-3x) sin(4-3x)
Thus, c is the correct answer.
