First, it is important to know that speed is equal to distance divided by time. I took a picture of my work. Let me know if you still have questions or cannot read something I've written. Thank you!
The most Kilometers traveled per one hour was traveled by THE BOAT at 75 Km/h. Therefore, the boat had the fastestaverage speed.
Explanation:
Midline: it is a horizontal line where half of the function above it and half of the function is below it.
Amplitude: It means how far the function varies from the midline to the above and below.
Period: the distance between two consecutive maximum points (minimum points).
3) From the graph,

Answer: Midline=1
1) Amplitude

2) Periods

4) The trigonometric equation is,

Answer:
Part 1) The perimeter is 
Part 2) The area is 
Step-by-step explanation:
Part 1) Find the perimeter
we know that
The perimeter is equal to the circumference of the exterior circle plus the circumference of the interior circle
so


Part 2) Find the area
we know that
The area of the figure is equal to the area of the larger circle minus the area of the smaller circle
so
