Answer:
f(x) + g(x) = x² – 3x + 24, <u>with some assumptions on what is meant in the question.</u>
Step-by-step explanation:
f(x) = x² – 3x 18 <u>[I'll assume this is meant to be x²-3x +18]</u>
g(x) = r = 6 <u>[I don't understand this. I'll assume simply that g(x) = 6]</u>
f(x) + g(x) = x² – 3x <u>+</u> 18 + <u>6</u>
f(x) + g(x) = x² – 3x + 24

We are told that the boat can travel 25 miles upstream in 5 hours. That comes to
25 miles
------------ = 5 mph.
5 hours
In the same 5 hours, that boat can travel 50 miles downstream. That comes to
50 miles
------------ = 10 mph
5 hours
Was there more to this question than the above?
Note: "It can go 50 miles downstream IN the same time (5 hours)."
Yes, you are correct to use proportions because they are similar triangles.
So the formula for the area of the circle is
. To find the radius is divide the diameters by 2, which in this case its 2 and 3. Now we can find the areas.
Now just subtract the areas:
The difference in areas is 5 pi, or 15.71.
