Answer:
x^2-2x+1
Step-by-step explanation:
f(x)=x^2
g(x)=x-1
f(g(x))=f(x-1)=(x-1)^2=x^2-2x+1
volume of the box is 675 cubic inches
A machine produces open boxes using square sheets of plastic.
It is a square sheet so length and width are same
Lets assume length as x so width is also x
The machine cuts equal-sized squares measuring 3 inches on a side from each corner of the sheet.
After turning up the sides the height of the box becomes 3 inches
We know the volume of a box formula
Volume = Length * width * height
We know length is x , width is x and height = 3
So V = x * x * 3
Given volume = 675 cubic inches
![675 = x * x * 3](https://tex.z-dn.net/?f=675%20%3D%20x%20%2A%20x%20%2A%203)
![675 = x^2* 3](https://tex.z-dn.net/?f=675%20%3D%20x%5E2%2A%203)
Divide by 3 on both sides
![225 = x^2](https://tex.z-dn.net/?f=225%20%3D%20x%5E2)
Now we take square root on both sides
x = 15
the length of one side of the open box is 15 inches.
Answer:
Lowest is 100
Highest is 125
Step-by-step explanation:
We use the 5 number summary to be the foundation of a graphical representation referred to as the box plot. One box would move from one quartile which is the lowest quartile Q1 to the another quartile Q3 which is the upper quartile.
Now if a box plot is to be made given the the information in this question, the box is going to go from Quartile 1 to Quartile 3.
Then the Lowest value would be 100 and the highest 125
![\dfrac{x^3+10x^2+13x+39}{x^2+2x+1}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%5E3%2B10x%5E2%2B13x%2B39%7D%7Bx%5E2%2B2x%2B1%7D)
, and
. Subtracting this from the numerator gives a remainder of
![(x^3+10x^2+13x+39)-(x^3+2x^2+x)=8x^2+12x+39](https://tex.z-dn.net/?f=%28x%5E3%2B10x%5E2%2B13x%2B39%29-%28x%5E3%2B2x%5E2%2Bx%29%3D8x%5E2%2B12x%2B39)
, and
. Subtracting this from the previous remainder gives a new remainder of
![(8x^2+12x+39)-(8x^2+16x+8)=-4x+31](https://tex.z-dn.net/?f=%288x%5E2%2B12x%2B39%29-%288x%5E2%2B16x%2B8%29%3D-4x%2B31)
is not a multiple of
, so we're done. Then
![\dfrac{x^3+10x^2+13x+39}{x^2+2x+1}=x+8+\dfrac{-4x+31}{x^2+2x+1}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%5E3%2B10x%5E2%2B13x%2B39%7D%7Bx%5E2%2B2x%2B1%7D%3Dx%2B8%2B%5Cdfrac%7B-4x%2B31%7D%7Bx%5E2%2B2x%2B1%7D)
