Answer:
C. 3 gallons
Step-by-step explanation:
30 ft × 18 ft = 540 ft²
540 ft² ÷ 250 = 2.16
2.16 is not an option so you would have to buy 3 gallons and only use 2.16 gallons.
The answer is (y - 4)2 = -12(x - 2)
Since the graph is facing the left, the starting equation would be (y - k)2 = -4p(x - h).
(h, k) is the vertex of the graph. If you plot the focus and the directrix, you can see that the distance is 6. Divide 6 by 2, thus the vertex should be 3 squares away from the focus and 3 squares away from the directrix. The vertex is (2, 4). And since the distance from the focus to the vertex and the distance from the directrix to the vertex is 3, P = 3.
Insert the numbers in and you should get the last choice.
2.3 + w > 18
-2.3 -2.3
w > 15.7
Answer
Is there any numbers or is it just like that?
