Answer:
22 miles per hour
Step-by-step explanation:
Against the current, the boat's rate of travel is ...
(120 mi)/(6 h) = 20 mi/h
With the current, the boat's rate of travel is ...
(120 mi)/(5 h) = 24 mi/h
___
The sum of boat speed (b) and current speed (c) is 24 mph. The difference is 20 mph. This lets us write the equations ...
b + c = 24
b - c = 20
Adding these two equations together, we get ...
2b + 0c = 44
b = 22 . . . . . . . . divide by 2
The rate of the boat in still water is 22 miles per hour.
Answer:
1/3 or 33.33%
Step-by-step explanation:
1/2 * 2/3 = 1/3
I am sure it is y= 8x+6
Hope I helped!
Answer:
Quadratic
Step-by-step explanation:
It's not linear because the speed of the penny is not<u> </u>constant.
It is not exponential because the speed does not continuously increase at a faster rate.
It is Quadratic because the penny will increase speed as you throw it up into the air. Once it reaches its "high point" it's speed hits 0, which is the origin of the quadratic equation. Then the speed increases faster and faster as it falls.
