Trava [24]
Profit for August: x
Profit for September: x - 22%x
Total Profit for August & September: $689,000

x + x - 22% x = 689,000

2x - .22x = 689,000
1.78x = 689,000
x = 689,000/1.78
x = 387,078.65

August Profits: $387,078.65
September Profits: 387,078.65 - (22%)(387,078.65) = 387,078.65 - 85,157.30 = 301,921.35

Helen [10]

Answer:

y= 1/12(x-0)^2+0

this answer works as an upward parabola

Step-by-step explanation:

  • The formula for a veritcal parabola is y=1/4p(x-h)^2+k
  • (h,k)= coordinates of the vertex of the parabola
  • p= absolute value of the distance from the vertex to the focus/directrix
  • In this problem, it is given that the vertex is at the origin (0,0) and the focus (the bulb), is 3 centimeters away from the vertex.
  • Now, you know the values of the variables. Fill in the values
  • FROM THE FORMULA: 1/4p turns into 1/12 since p is 3.
  • (x-h)^2+k turns into (x-0)^2+0, since h and k where the values of the vertex which was 0,0
  • once all the variables are given values (except x and y) you have made your equation!
  • The answer is y=1/12(x-0)^2+0
