Answer:
The repair person did 5 hours of work.
Step-by-step explanation:
155 = 25x + 30
125 = 25x
5 = x
Answer:
47
Step-by-step explanation:
this is due to when 286 is divided by 61 it gets 40 and the remainder gets you 7 as a result it is 47
Answer:
True. See the explanation and proof below.
Step-by-step explanation:
For this case we need to remeber the definition of linear transformation.
Let A and B be vector spaces with same scalars. A map defined as T: A >B is called a linear transformation from A to B if satisfy these two conditions:
1) T(x+y) = T(x) + T(y)
2) T(cv) = cT(v)
For all vectors
and for all scalars
. And A is called the domain and B the codomain of T.
Proof
For this case the tranformation proposed is t:
Where
For this case we have the following assumption:
1) The transpose of an nxm matrix is an nxm matrix
And the following conditions:
2) ![T(A+B) = (A+B)^T = A^T + B^T = T(A) + T(B)](https://tex.z-dn.net/?f=T%28A%2BB%29%20%3D%20%28A%2BB%29%5ET%20%3D%20A%5ET%20%2B%20B%5ET%20%3D%20T%28A%29%20%2B%20T%28B%29)
And we can express like this ![T(A+B) =T(A) + T(B)](https://tex.z-dn.net/?f=%20T%28A%2BB%29%20%3DT%28A%29%20%2B%20T%28B%29)
3) If
and
then we have this:
![T(cA) = (cA)^T = cA^T = cT(A)](https://tex.z-dn.net/?f=%20T%28cA%29%20%3D%20%28cA%29%5ET%20%3D%20cA%5ET%20%3D%20cT%28A%29)
And since we have all the conditions satisfied, we can conclude that T is a linear transformation on this case.
