Answer:
400 villas
Step-by-step explanation:
Since R(x)=200x−0.25x2 is a quadratic function with a negative leading coefficient, it represents a parabola opening downward. So its vertex will be the maximum of the function. If the coefficients are labeled, we have a=−0.25, b=200, and c=0. Then the vertex is found as follows.
x=−b/2a=−200/2(−0.25)=400
Therefore, maximum revenue will be attained when 400 villas are booked.
Answer:
9,43
Step-by-step explanation:
9 times 5 is 45. Then you subtract 2.
The coordinates of the center of the circle are found in (h, k). The h coordinate is stuck with the x, and the k coordinate is stuck with the y. They are in the form (x-h) and (y-k). So if our first center coordinate is found in (x-4), then the h value is 4. Our other center coordinate is found in (y+12) which started like this: (y-(-12)). So the k value is -12. The center then is (4, -12).
