Answer:
the maximum value is 3
Step-by-step explanation:
The maximum value of the function y = -2+5sin(pi/12(x-2)) is determined by taking the first derivative of the function. The first derivative is equal ( 5 pi/ 12 )* sin ((pi/12) (x-2)) = 0. x is equal to 4472 through the calculator. Substituting to the original equation, the maximum value is 3.
Answer:
average speed = (55 + 70 + 525) / 6
= 650 / 6
= 108.33 km per hour
Step-by-step explanation:
first hour = 55 per hour.
= 55
second and third = 35 per hour.
= 70
fourth, fifth and sixth = 175 per hour.
= 525
average speed = (55 + 70 + 525) / 6
= 650 / 6
= 108.33 km per hour
