Yes!
The rate can be expressed by the ratio 3:1
For every 3 bottles, its $1
For every 6 bottles, its $2
For every 12 bottles its $4
and for every 18 bottles its $6
The juice's are equivalent because the ratio of number to bottles to dollars is equal.
Step-by-step explanation:
Answer:
x^2 +y^2 = 4y
Step-by-step explanation:
Using the usual translation relations, we have ...
r^2 = x^2+y^2
x = r·cos(θ)
y = r·sin(θ)
Substituting for sin(θ) the equation becomes ...
r = 4sin(θ)
r = 4(y/r)
r^2 = 4y
Then, substituting for r^2 we get ...
x^2 +y^2 = 4y . . . . . matches the first choice
