How do I find the midpoint

Hunter-Best [27]

To find the midpoint of a line use the midpoint formula which is M = (x1+x2/2 , y1 +y2/2) After plugging in the coordinates for your variables you should get (-1+5/2, -1+2/2) This simplifies to (2, 1/2) which is the coordinates for the middle point of the base XY.

Given

First, we determine the cost function for all the three rides.

Ride A

From the graph, we have the following points

$(x_1,y_1) = (0,8)$

$(x_2,y_2) = (2,12)$

Calculate slope

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{12-8}{2-0}$

$m = \frac{4}{2}$

$m =2$ --- This represents the rate per ride

The equation is the calculated as:

$y = m(x - x_1) + y_1$

So, we have:

$y = 2(x - 0) + 8$

$y = 2(x) + 8$

$y = 2x + 8$

So, the cost function is:

$C(x) =2x + 8$

Calculate the cost of admission i.e. x=0

$C(0) = 2*0+8 = 8$

So, we have:

$C(0) = 8$ --- Admission Charge

$C(x) =2x + 8$ --- Cost function

$m =2$ --- Rate per ride

Ride B

From the table, we have the following points

$(x_1,y_1) = (0,12)$

$(x_2,y_2) = (4,15)$

Calculate slope

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{15-12}{4-0}$

$m = \frac{3}{4}$

$m = 0.75$ --- This represents the rate per ride

The equation is the calculated as:

$y = m(x - x_1) + y_1$

So, we have:

$y = 0.75(x - 0) + 12$

$y = 0.75(x) + 12$

$y = 0.75x + 12$

So, the cost function is:

$C(x) = 0.75x + 12$

Calculate the cost of admission i.e. x=0

$C(0) = 0.75*0 + 12=12$

So, we have:

$C(0) =12$ --- Admission Charge

$C(x) = 0.75x + 12$ --- Cost function

$m = 0.75$ --- Rate per ride

Ride C

No additional fee;

So, the cost function is;

$C(x) = 30$

In summary, we have:

Ride A

$C(x) =2x + 8$ --- Cost function

$m =2$ --- Rate per ride

Ride B

$C(x) = 0.75x + 12$ --- Cost function

$m = 0.75$ --- Rate per ride

Ride C

$C(x) = 30$ --- Cost function

By comparison

Ride A has the highest rate per ride of (#2), followed by ride B with a rate of #0.75 per ride.

Ride C has no charges per ride

The impact on the total cost is that:

Ride A: People that opt for ride A will pay the least to get admitted (i.e #8) but they pay the most (i.e. #2) per each ride they take

Ride B: People that opt for ride B will pay #12 to get admitted, but they pay 0.75 per each ride they take

For A and B, the overall cost depends on the number of rides taken.

Ride C: Irrespective of the number of rides taken, people that opt for ride C will pay the same flat fee of #30
