Six months after a divorce, the former wife and husband each take a test that measures divorce adjustment. The wife’s score is 6
olasank [31]
Note that
(63 – 60)/6 = 1/2
(59 – 55)/4 = 1
So, in relation to other divorced women, the score of 63 is only 1/2 SD above the average. But in relation to other divorced men, the score of 59 is 1 SD above the average. That means the husband has adjusted better to the divorce in the relation to other divorced people of his gender.

The function f determines the volume of the box (in cubic inches) given a cutout length (in inches). Use function notation to re
Alenkinab [10]

<u>Complete Question</u>

A box is formed by cutting squares from the four corners of a sheet of paper and folding up the sides. However, the size of the paper is unknown!

Answer:

(a)f(0.2)=0.2(l-0.4)(w-0.4)

(b)f(1.3)=1.3(l-2.6)(w-2.6)

(c)f(1.3)-f(0.2)

(d) f(5.6)-f(5.5)

Step-by-step explanation:

Let the Length of the paper =l  (in inches)

Let the Width of the paper =w  (in inches)

Let the length of the cutout square = x (in inches)

  • Base Length of the Box = l-2x
  • Base Width of the box =w-2x
  • Height of the box =x

Volume of the box: f(x)=x(l-2x)(w-2x)

(a)When the cutout length is 0.2 inches.

x=0.2

Volume of the box (in cubic inches) ,

f(0.2)=0.2(l-0.4)(w-0.4)

(b)When the cutout length is 01.3 inches.

x=1.3

Volume of the box (in cubic inches) ,

f(1.3)=1.3(l-2.6)(w-2.6)

(c)If the cutout length increases from 0.2 inches to 1.3 inches.

Change In volume (in cubic inches):

f(1.3)-f(0.2)\\=1.3(l-2.6)(w-2.6)-0.2(l-0.4)(w-0.4)

(d)If the cutout length increases from 5.5 inches to 5.6 inches.

Change In volume (in cubic inches):

f(5.6)-f(5.5)\\=5.6(l-11.2)(w-11.2)-5.5(l-11)(w-11)
