Y is directly proportional to the square root of x If y = 32 when x = 64 find,
y when x = 25

Please help

y = 20

Step-by-step explanation:

Given y is directly proportional to , then the equation relating them is

y = k ← k is the constant of proportion

To find k use the condition y = 32 when x = 64, then

32 = k = 8k ( divide both sides by 8 )

4 = k

y = 4 ← equation of proportion

When x = 25, then

y = 4 = 4 × 5 = 20

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
