Alicia, the manager of a plant, determines that when x% of the plant’s capacity is being used, the total cost of the operation is c hundred dollars, where: [tex]c(x) = \frac{8x^2-636x-320}{x^2-68x-960}[/ tex]the company has a policy of rotating maintenance in an attempt to ensure that approximately 80% of capacity is always in use. what cost should alicia expect when the plant is operating at this ideal capacity?

step-by-step explanation:

i just know the internet

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.

the ratio would be 4: 3, the four being for jackson, and the three being not for him.
