A green box contains a blue box and a pink box. The blue box contains C H subscript 4 + 2 O subscript 2. An arrow then leads in the green box to the pink box, which says C O subscript 2 + 2 H subscript 2 O. Lines lead from labels to parts of the boxes. Label A leads to the beginning of the green box. Label B leads to the + in the blue box. Label C leads to the arrow. Label D leads to the 2 in 2 H subscript 2 O. Label E leads to the end of the pink box. Identify each part of this chemical equation that describes the burning of methane and oxygen.

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

step-by-step explanation:

this is not a question

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
