Step-by-step explanation:
The equation of a parabola that relates it focus is

So here, we isolate x^2.


Next, we factor out 4.

Our p=8 so this tells us the distance of the vertex to the focus.
Answer:
Sarah is Correct
Step-by-step explanation:
If we are given the area of a circle as 44 Square Centimeter, we know that:
Area of a Circle
Circumference of a Circle 
Therefore, from the area, we can obtain the value of the radius to calculate the circumference of the circle:

Therefore:
Circumference of the circle
=23.51 centimeters.
Since the sandwich cost 3 times as much as the chips and the sandwich is $6 then the chips must cost $2.
C = 6(5) + 2b
42 = 30 + 2b
12 = 2b
6 = b
Answer: Casey bought 6 bags of chips
