he graph below shows the price of different numbers of cans of beans at a store: A graph is shown. The values on the x axis are

0, 2, 4, 6, 8, 10. The values on the y axis are 0, 19, 38, 57, 76, and 95. Points are shown on ordered pairs 0, 0 and 2, 19 and 4, 38 and 6, 57 and 8, 76. These points are connected by a line. The label on the x axis is Number of Cans. The title on the y axis is Price in dollars. Which equation can be used to determine p, the cost of b cans of beans?

Since p is the y-axis and b is the x-axis and we have the "plots", we can form this equation

y = 9.5x
substitute p into y and b into x
p = 9.5b

i hope i helped!

A parabola has a focus of F(2, -0.5) and a directrix of y=-1.5 P(x,y) represents any point on the parabola, while D(x, -1.5) rep
prohojiy [21]
The sketch of the parabola is attached below

We have the focus (a,b) = (2, -0.5)
The point P(x,y)
The directrix, c at y=-1.5

The steps to find the equation of the parabola are as follows

Step 1
Find the distance between the focus and the point P using Pythagoras. We have two coordinates; (2, -0.5) and (x,y).
We need the vertical and horizontal distances to find the hypotenuse (the diagram is shown in the second diagram).
The distance between the focus and point P is given by
\sqrt{ (x-a)^{2}+ (y-b)^{2} }

Step 2
Find the distance between the point P to the directrix c. It is a vertical distance between y and c, expressed as y-c

Step 3
The equation of parabola is then given as 
\sqrt{ (x-a)^{2}+ (y-b)^{2} }=y-c
(x-a)^{2}+ (y-b)^{2}= (y-c)^{2} ⇒ substituting a, b and c
(x-2)^{2}+ (y--0.5)^{2}  = (y--1.5)^{2}
(x-2)^{2}+ (y+0.5)^{2}= (y+1.5)^{2}⇒Rearranging and making y the subject gives

y= \frac{ x^{2} }{2} -2x+1

Answer:

78.5 or 79 inches when rounded.

Step-by-step explanation:

2 in wide so get half of 2 which is 1 times 3.14 = 3.14. then times that by the 25 inch radius = 78.5
