For the line segment whose endpoints are X(1, 2) and Y(6, 7), find the x value for the
finlep [7]

Answer:

3) 2.7

Step-by-step explanation:

The distance between two points (x_1,y_1) and (x_2,y_2) can be determined by:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Since the points are X(1, 2) and Y(6, 7). The distance between the two points is

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(6-1)^2+(7-2)^2}=\sqrt{50}

the x value for the  point located 1/3 the distance from X to Y,

x=\frac{x_2-x_1}{3}=\frac{6-1}{3}=1.7

The x value = x_1+1.7 = 1+1.7 = 2.7

Mr. Shamir employs two part-time typists, Inna and Jim, for his typing needs. Inna charges $15 an hour and can type 6 pages an h
coldgirl [10]

Answer:

The minimum cost would be 480$ when Inna works for 8 hours and Jim works for 20 hours.

Step-by-step explanation:

We are given the following information in the question:

Charges for 1 hour for Inna = $15

Number of pages typed by Inna in 1 hour = 6

Charges for 1 hour for Jim = $18

Number of pages typed by Jim in 1 hour = 8

Let x be the number of hours Inna work and let y be the number of hours Jim work.

Total cost = 15x + 18y

We have to minimize this cost.

Then, we can write the following inequalities:

6x + 8y \geq 208\\x \geq 8\\y \geq 8\\

The corner points as evaluated from graph are: (8,20) and (24,8)

C(8,20) = 480$

C(24,8) = 504$

Hence, the minimum cost would be 480$ when Inna works for 8 hours and Jim works for 20 hours.

The attached image shows the graph.
