The table shows the number of games a chess player won in professional competitions, based on the number of games played.
AfilCa [17]

slope  = (25-4)/(30-10)

 slope = 21/20

slope =21/20  

using point slope form

y-y1 = m(x-x1)

y-4 = 21/20 (x-10)

y = 21/20x -21/2 +4

y = 21/20 x -21/2 +8/2

y = 21/20x -13/2


let x=40

y = 21/20 (40) -13/2

y = 42-13/2

y = 35.5 games


If we round the slope to 1

slope =1

using point slope form

y-y1 = m(x-x1)

y-4 = 1 (x-10)

y = 1x -10 +4

y =  x -6


let x=40

y = 40-6

y = 34 games

Describe in words the relationship between the length, width and height of a cuboid and its volume. ​
Sergio [31]

Volume = length * width * height

Each asterisk * refers to the multiplication symbol

The volume of the cube is equal to the length times width times height

---------------------

Example:

Consider a cube that has length, width and height each equal to 4 cm

Volume = length * width * height

Volume = (4 cm) * (4 cm) * (4 cm)

Volume = (4*4*4) cubic cm

Volume = 64 cubic cm

----------------------

Another example:

We have a rectangular prism that has the following dimensions

length = 4 ft

width = 3 ft

height = 5 ft

Computing the volume gets us:

Volume = length * width * height

Volume = (4 ft) * (3 ft) * (5 ft)

Volume = (4*3*5) cubic ft

Volume = 60 cubic ft
