Answer:
2x2 matrix
Step-by-step explanation:
Given
Dimension of matrices A = 2x2 matrix
Dimension of matrices B = 2x1 matrix
The dimension of matrix AB can be gotten by cancelling the row of matrices 1 and column of matrices 2.
After cancelling both row and column, the remaining dimension will be 2x2 matrix. Hence the dimension of AB is 2x2 matrix
Answer:
$1,326
Step-by-step explanation:
You are going to want to use the simple interest formula for this.

<em>I = interest amount
</em>
<em>P = principal amount
</em>
<em>r = interest rate</em>
<em>t = time</em>
First, change 1.7% into its decimal form:
1.7% ->
-> 0.017
Next plug in the values into the equation:


After three years, he must repay $1,326.
250 miles ÷ 4.5 hours = 56 mph (rounded from 55.55555)
Answer:
The width of the room is 17.25 feet
Step-by-step explanation:
2(15.75+W)=66
Divide both sides by 2: 15.75+W=33
Subtract 15.75 from both sides: W=33-15.75=17.25
Hope this helps!
