Answer(a):
Order of matrix A = 3x3 {because number of rows=3, number of columns=3}
Order of matrix B = 3x3
Order of matrix C = 1x3
3A will be of order 3x3 because multiply by scalar doesn't change the order. Which is same as the order of matrix B.
So 3A+B is possible.
We simply multiply all elements of A with 3 and add them with corresponding elements of B.
Answer(b):
2B will be of order 3x3 because multiply by scalar doesn't change the order. Which is NOT same as the order of matrix C.
So 2B+C is NOT possible.
Answer(c):
CA is possible only if
number of columns of C = number of columns of A
3=3
which is true hence CA is possible.

Answer:
(b) 33
Step-by-step explanation:
The side opposite x° and the hypotenuse are given. That means the relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(x°) = 6/11
The value of the angle is found using the inverse sine function:
x° = arcsin(6/11) ≈ 33.056°
x ≈ 33
_____
<em>Additional comment</em>
If you recall, the side length ratios of the "special" 30°-60°-90° triangle are 1:√3:2. Here, you have a shortest:longest side ratio that is 6:11 ≈ 6:12 = 1:2. This means the angle will be only slightly greater than 30°.
The value of k will be 3 if the function is transformed by compression factor of 3
Step-by-step explanation:
The horizontal stretch or compression for a function f(x) is given by g = f(bx) where b is a constant. If b> 0 then the graph of function is compressed.
As it is given in the question that he function is transformed by a compression factor of 3.
