Cala uses 2 pounds of feed-all fertilizer for a 100 foot row of vegetables at her farm. at this rate, how many pounds of fertilizer would she use for a 450-foot row of vegetables? explain

Answer

Find out the how many fertilizer she used for a 450-foot row of vegetables.

To proof

let us assume that the fertilizer would she use for a 450-foot row of vegetables be x.

As given

Cala uses 2 pounds of Feed-All fertilizer for a 100 foot row of vegetables at her farm.    

than the equation becomes

solving the above

x = 9 pound

Therefore 9 pound are used  for a 450-foot row of vegetables.

Hence proved

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

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
