D
Step-by-step explanation:
Explanation, in 2 hours car B is at 120 miles east of Johnstown. and is 2 hours car A is 130 miles east of Johnstown.
Hello here is a solution :
f'(x) =( sin11x)'cos11x +<span>sin11x(cos11x)'
(sin(ax+b))'=a cos(ax+b)
</span>(cos(ax+b))'=-a sin(ax+b)
f'(x) = 11 cos11xcos11x-11sin11xsin11x
f'(x) = 11(cos11x)²-11(sin11x)²
