Answer:
Step-by-step explanation:
The average value theorem sets:
if f (x) is continuous in [a, b] and derivable in (a, b) there is a c Є (a, b) such that
, where
f(a)=f(π/2)=-4*sin(π/2) = -4*1= -4
f(b)=(3π/2)=-4*sin(3π/2) = -4*-1 = 4


⇒

c≅130
Answer:
16 minutes
Step-by-step explanation:
80% of 20 is
80/100 * 20 = 16
Answer:3
Step-by-step explanation:
If you add a zero at the end it is easier to understand. 0.20 > 0.18 because 20 is greater than 18
