Since the surface is the top part of a sphere centred on the origin, the directions of steepest descent are any vector originating from the origin (0,0).
At (5,5), the direction would be dictated by the line joining (5,5) and the origin (0,0), i.e. along <5,5> or equivalently along <1,1>.
You can also go through vector calculus to arrive at the same result.

Answer:
5 hours
Step-by-step explanation:
The total cost is the fee plus the hours* hourly cost
450 = 200+50*h where h is the hours
Subtract 200 from each side
450-200 = 200-200 +50h
250 = 50h
Divide each side by 50
250/50 = 50h/50
5 = h

Answer:
No
Step-by-step explanation:
If the line did pass through that point, then plugging in the point to the equation would be true. But when you plug in 4 for x, the y would be 18, not 15.
Answer:
your answer would be g
