Answer:
The speed from the observer is 8 mph.
Step-by-step explanation:
When the boat is going downstream with full force, its speed will be the one the oarsman can row on still water added by the flow of the river. In this case he can row the boat at speed of 3 mph, while the stream is 5 mph, so the speed from the observer standpoint is:

The speed from the observer is 8 mph.
Y=5 it's a horizontal lines so b in y=mx+b would have to be 5 and since it's horizonal, it doesn't have a slope so it's just y=5
I believe the expression would be 7(g)+7
Answer:
Option C) 113.0 feet squared
Step-by-step explanation:
We are given the following in the question:
Radius of circular garden = 4 feet
Length of path around garden = 2 feet
We have to find the total area of garden and path.
The garden and path together makes a bigger circle with radius

Area of garden and path =

Putting values, we get,

Thus, the correct answer is
Option C) 113.0 feet squared
