Answer:
The value of AB is and it's not possible to multiply BA.
Step-by-step explanation:
Consider the provided matrices.
,
Two matrices can be multiplied if and only if first matrix has an order m × n and second matrix has an order n × v.
Multiply AB
Matrix A has order 2 × 2 and matrix B has order 2 × 1. So according to rule we can multiply both the matrix as shown:
Hence, the value of AB is
Now calculate the value of BA as shown:
Multiply BA
Matrix B has order 2 × 1 and matrix A has order 2 × 2. So according to rule we cannot multiply both the matrix.
We can multiply two matrix if first matrix has an order m × n and second matrix has an order n × v.
That means number of column of first matrix should be equal to the number of rows of second matrix.
Hence, it's not possible to multiply BA.
Answer:
30%
Step-by-step explanation:
total boxes of pizza = 20
he gave away 14 boxes
so pizza left is 20 - 14 = 6 boxes
to calculate percentage = 6 / 20 * 100
= 6 * 5
= 30%
Answer
C) 40 degrees
Step-by-step explanation:
I would use the inscribed angle theorem as proof. The inscribed angle theorem means that the angle m EFG = x and line EG(80 degrees) = 2x
2x = 80
40 degrees
x = 40 degrees
