Answer:
Option 3. y = csc ∅ is the right answer.
Step-by-step explanation:
In a function y = cosec ∅ we put the value of ∅ at 0,π/4,π/2,π,3π/2.
y = cosec 0 = ∞ Therefore function is not defined at ∅ = 0
y = cosec π/4 = √2 = 1.41
y = cosec π/2 = 1
y = cosec π = ∞ not defined
y = cosec 3π/2 = -1
y = cosec 2π = ∞ again not defined
While analyzing the value of expression we can say that the graph is of y = cosec ∅.
Similarly if we analyze other expressions for the values of ∅ then the graph will not match.

From the diagram, Vertex =(2,3)
So, (h,k)=(2,3)
So, h=2 and k=3
The equation of parabola is
p is the distance of directrix or focus from vertex.
As directrix is
y=8=k-p=3-p
So, 8=3-p
Let, us subtract 3 from both sides, we get
8-3=3-3-p
5=-p
or p=-5
So, h=2,k=3 and p=-5
So, the equation of parabola is
=4(-5)(y-3)
Equation of graph is
(x-2)^2=-20(y-3)

Melinda sold 8 packages of coffee and 6 packages of pastries
Step-by-step explanation:
The parameters given are;
Number of Packages of coffee = x
Number of Packages of pastries = y
Price of each package of coffee = $6
Price of each package of coffee = $4
Number of packages of packages of coffee sold = 2 more than packages of packages pastries sold
x = 2 + y
y = x - 2................(1)
Sum of money made in the fundraiser = $72
∴ x × $6 + y × $4 = $72
y = ($72 - x × $6)/$4 = 18 - 3/2·x
y = 18 - 3/2·x.........(2)
The solution is
x - 2 = 18 - 3/2·x
x + 3/2 = 18 + 2 = 20
5/2·x = 20
x = 2/5×20 = 8
y = x - 2 = 8 - 2 = 6
The ratio is 11 : 7. I.e the number of red apples are 11 and that of green are 7
