Answer:
Daniel's is correct
Step-by-step explanation:
Daniel split the coin toss into Heads and Tails and has 3 sections for the spinner coming off of each coin toss branch.
draw a perpendicular line from the directrix passing through the focus, this will be the line of symmetry.
The vertex(h, k) will be located on the line half way between the focus and directrix.
The distance from the focus to the vertex is called the focal length, call it a. The then equation is
(x - h)^2 = 4a(y - k)
the equation can be manipulated to
y = 1/4a(x - h)^2 + k

Step-by-step explanation:
Answer:
so, the width of the poster is 8.185 inches [rounded] / √67 inches
and the length of the poster is 13.185 inches [rounded] / √67 + 5 inches
Step-by-step explanation:
( area can be found with the formula l × w [length × width] )
I will call the width "x"
w · l = 72
x · x + 5 = 72
- 5 - 5
x · x = 67
x² = 67
√x² = √67
x ≈ 8.185
(x = √67)
so, by adding 5 inches, we get that
x + 5
8.185 + 5 [√67 + 5]
length = 13.185
so, the width of the poster is 8.185 inches [rounded] / √67 inches
and the length of the poster is 13.185 inches [rounded] / √67 + 5 inches
