Part A: 14 + 14 = y or 14•2 = y
Part B: (n•2) - 2 = a
Not 100% sure that this is correct but, hope this helps! :) If you have any questions than ask me.
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

One tenth is equal to .1 or 1/10
and .04 is nothing but 4/100
So just multiply them together:
1/10 x 4/100 = 4/1000
And since there are 3 0's we need to move the decimal spot 3 places the the left:
.004
So our final answer is
