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.
Step-by-step explanation:
<AOF and <COD are vertical angles.
m<AOF = m<COD = 80°
Angle Addition Postulate m<BOF - m<AOF = m<AOB
m<AOB = 135° - 80° = 55°
Answer: -1/4
Step-by-step explanation:
- (0,3) and (4,2) are (x1, y1) and (x2, y2)
- slope =
<span>The answer is powers of ten. A power of ten is 10 multiplied by itself the exponent number of times. For example, 10 = 10^1. 100 = 10 * 10 = 10^2. 1000 = 10 * 10 * 10 = 10^3. The number of zeros in the power of ten must match its exponent. For instance, 1000 has 3 zeros so the exponent is 3: 1000 = 10^3.Hope this helps. Let me know if you need additional help!</span>
