Need help with Linear Algebra 10 minute quiz, NEED 4/5

Hi there, once I start I need to answer 5 questions within 10 minutes, if you can get me a 4/5 that’d be perfect, a previous attempts questions are posted, the new questions will randomize but will be very similar, thanks!.

– Question 1
What is the image of the point (40,25) under the following transformation contraction by a factor of 5, then projection onto the y-
axis
1 point
This question accepts answers that are in a form like “(-1,3)” or “(3,7,3z)”.
The entries can be numbers or formulas

– Question 2
What is the image of the point (0,1) under the following transformation: dilation by a factor of 8, then counterclockwise rotation by
270 degrees, then reflection about the y-axis?
1 point
This question accepts answers that are in a form like “(-1,3)” or “(3,7,32)”.

– Question 3
The following linear operator is one-to-one: orthogonal projection onto the y-axis in R2
1 point
O True
O False
Question 4
-6
If TAR? > R2 is multiplication by A where A is given by
, then the range of TA is all of R
6
-2
1 point
O True
O False
Question 5
Suppose we apply the following transformations (in the order listed) to an image in Rº, originally called View 1.
M1: Scale: (i.e. stretch) by a factor of 6 in each of the x, y, and z-directions
M2: Translate: (i.e. shift) 6 units in the x-direction
M3: Rotate: about the origin through a negative angle of 270 degrees
1 point
Here, M1, M2, and M3 denote the three matrices associated with these transformations.
If P is the coordinate matrix of the original view (View 1) and P’ is the coordinate matrix of the resulting image after the
transformations (View 2), which of the following gives p’ in terms of M1, M2, M3, and P?
[This question is based on your assigned pre-reading/prep for the upcoming Assignment]
M3+M2MP
M3(M2+M P)
O none of these
OM (M2+M3P)
