4. street horizontal distance (ft) vertical rise of street (ft)
dixie hill 80 40
bell hill 80 20
liberty hill 80 60
which hill described in the table is the steepest?
explain.

a. bell hill; it rises one foot for every 4 feet of horizontal travel.
b. dixie hill; it rises 2 feet for every 1 foot of horizontal travel.
c. liberty hill; it rises 4 feet for every 3 feet of horizontal travel.
d. liberty hill; it rises foot for every 1 foot of horizontal trave

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
