The standard form for this parabola is x = a(y-k)^2 + h because this is a sideways-opening parabola. Our h and k values for the vertex are (-4, -1). And it goes through (2,0). We just need to solve for the a. Filling in accordingly, 2 = a(0+1)^2-4 so 2 = a - 4. a = 6. A above.
correct answer is 6!

Answer:
50 days
Step-by-step explanation:
Step one:'
given data
Non member must pay a 6$ per day
let number of days be x
cost = 6x
member of the club pay 1$ but must pay a yearly membership fee of 250
cost = 250+x
Step two
equate the two expression to find x
6x=250+x
6x-x= 250
5x=250
divide both sides by 5
x= 250/5
x=50 days

Answer:
D 10/111
Step-by-step explanation:
20 apple+25 orange +30 milk = 75 total
P(oj) = oj/total = 25/75 = 1/3
No replacement 20 apple+24 orange +30 milk = 74 total
P(apple) = apple/total = 20/74 = 10/37
P(orange, no replace, apple) = 1/3 *10/37 =10/111
