Your friend incorrectly claims that 1/2 divided by 1/10 = 20. Find 1/2 divided by 1/10. Then describe what may have been your friend’s error.

Your friend is wrong because they forgot that when you divide fractions you actually multiply the first fraction by the reciprocal of the other fraction. So the answer is 5.

Step-by-step explanation:

1/2 / 1/10

1/2 * 10/1

=10/2

=5

And for your specific question the answer would be the first choice “reciprocal of the dividend by”

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

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
