Option D:
The dimensions of the matrices don't align properly to find their sum.
Solution:
Given data:
Dimension of matrix = Number of rows × Number of columns
Dimension of matrix is 2 × 1
Dimension of matrix is 2 × 2
Here, we have to add the two matrices.
<em>The dimension of the matrices must be same to add or subtract matrices.</em>
Here the dimensions are 2 × 1 and 2 × 2.
The dimensions are not same.
Hence we can't find their sum.
Option D is the correct answer.
The dimensions of the matrices don't align properly to find their sum.
Answer:
Step-by-step explanation:
The absolute maximum of a continuous function is where . Therefore, we must differentiate the function and then set and to determine the value of :
Therefore, when , the absolute maximum of the function is .

D
Step-by-step explanation:
Point slope form is written in
y - y1 = m(x - x1)
Where m is the slope and (x1, y1) is a point on the line.
Looking at the values we have m = 1/2 and x1 = 1, y1 = 4.
Therefore the slope is 1/2 and the point is (1,4)
