Step-by-step explanation:
A matrix is given by
Now, we have to find the matrix X if
⇒ X = 2A
Now, multiplication of a constant with a matrix means multiplication with that constant with all the terms of the matrix.
So,
⇒ (Answer)
Not going to do (1), (2), (3) since they are implicit from (a) and (b) and require graphs (which aren't supported on brainly).
We have , that means, if plug in
we get
.
Doman of cosine is .
Hope this helps.
Given:
The point is U'(-8,1).
It is translated along <2,0> and reflected across the x-axis.
To find:
The image of U'.
Solution:
The given point is U'(-8,1).
It is translated along <2,0> . So, the rule of translation is:
Then, it is reflected across the x-axis. So, the rule of reflection is:
The image of U'( -8 , 1) is U''(-6,-1).
Therefore, the correct option is A.
