Suppose we have a linear transformation x? ax where
[1 3 9 2
a= 1 0 3 4
0 1 2 3
2 3 0 5] ( a is matrix form 4 by 4)
a. find all x? r4 with ax = 0 (if any). give your solution in parameterized form.
b. determine if
y= [3
3
1
2]
y is in the range of a.
c. do the columns of a span r4 ? how do you know?

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

i would say true? if the unit was informational and it "refreshed your understanding", then true.

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
