Answer:
option C. Defined, 3 x 3
Step-by-step explanation:
The order of matrix A is 3 x 2 i.e 3 rows and 2 columns
The order of matrix B is 2 x 3 i.e. 2 rows and 3 columns
Two matrices can be multiplied if and only if the number of columns of 1st matrix is equal to the number of rows of 2nd matrix. Since the number of columns in matrix A is equal to the number of rows in matrix B, the product AB is defined.
The product AB will have number of rows equal to the rows of 1st matrix i.e. matrix A and number of columns equal to the columns of 2nd matrix i.e. matrix B.
So the order of AB will be 3 x 3 .
Therefore, the correct answer is option C. Defined 3 x 3
Let's break this down into what each piece is.
One flat= one whole= 1
One rod= one tenth= 0.1
One unit= one hundredth= 0.01
a) We have 1 flat, 3 rods, and 7 units. Using what we know, we have 1 whole, 3 tenths, and 7 hundredths. So, this is 1 + 0.3+ 0.07. This equals 1.37.
b) 1 flat, 37 units. This is 1 whole, and 37 hundredths. When there are two digits that you want to put in the hundredths place, put the digit furthest to the right in the hundredths place (excluding decimals) and place the rest of the number to the left accordingly. So for us, 37 hundredths would be .37, not .037. Add up 1 and .37, and we have 1.37.
c) 13 rods, 7 units. This is like the last problem. We have two digits wanted to go in the tenths place, but that isn't possible. So, we take the digit all the way to the right and put it in the tenths place (3). Now, we take out remaining digits (1), and put it in the next space to the left. Our rods= 1.3. Now for our units. We have 7, so that equals 0.07. Add it together, and now we have 1.37.
All of the problems equal 1.37. This shows how many ways a number can be represented.
