Al changes saved 4. The height of a wave can be represented by the function y = 3 cos ( (2-6)) + 4, with time in z hours. What are the maximum and minimum heights, and when do they occur
on the interval 0 <<24?

5050 i think

step-by-step explanation:

9 x 8 divided by (5-3)=36

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
