Check the picture below. Recall your SOH CAH TOA.
Answer:
The equation
represents the equation of the parabola with focus (-3, 3) and directrix y = 7.
Step-by-step explanation:
To find the equation of the parabola with focus (-3, 3) and directrix y = 7. We start by assuming a general point on the parabola (x, y).
Using the distance formula
, we find that the distance between (x, y) is

and the distance between (x, y) and the directrix y = 7 is
.
On the parabola, these distances are equal so, we solve for y:

If there are 45 beads, with a ratio of

Then,

Then if

Then

Therefore,

Meaning, there would be a ratio of 36 beads to 9 beads
