Answer:
A is spanned by vector.
Step-by-step explanation:
The null space of matrix is set of all solutions to matrix. The linearly independent vectors forms subset which are spanned and forms the null space. The null space of vector can be found by reducing its echelon. The non zero rows formed are the null spaces of matrix.
Answer:
1.5 - 1 1/5 = 3

= 0.3
Step-by-step explanation:
R=i/pt
R=1680/3000*8=1,680÷24,000
=0.07*100=7%
Answer: 
<u>Step-by-step explanation:</u>
The vertex form of a parabola is: y = a(x - h)² + k where
- (h, k) is the vertex
NOTE: p is the distance from the vertex to the focus
The vertex (h, k) is (2, -3)

Insert those values into the vertex formula to get:

4:2 because it goes cars then buses
