Given,
Time taken by motorboat to going 200 miles upstream is 5 hours.
Time taken by motorboat to going 200 miles downstream is 4 hours.
At upstream,
The speed of boat is offosed by the speed of current.
At downstream,
The speed of boat is incraesed by the speed of current.
Consider,
The speed of boat is b.
The speed of current is c.
The speed is calculated as,
Similarly,
Substituting the value of b from equation (2) then,
Substituting the value of c in equation (1) then,
Hence, the speed of boat is 45 mile per hour and speed of current is 5 mile per hour.
The answer $456 because I guessed
Answer:
x ≥ 0
Step-by-step explanation:
The domain of the profit function G(x) is the set of all possible values that "x" could assume. In this function, "x"represents the sales in thousand of dollars, therefore the minimum possible value is zero (scenario in which there are no sales). Assuming an hypothetical scenario in which the company has an infinite supply capacity, there is no upper limit for what their sales might be. Thus, the domain for the function is x ≥ 0.
