A rhombus is a 4 sided shape with equal lengths. Even though it has equal lengths, it has opposite sides that are parallel, and angles that are equal. It also has diaginols (dashed lines) meat in the middle
Answer:
A) A is an invertible matrix ( TRUE )
B) A is a row equivalent to the n x n identity matrix ( n = 3 ) ( TRUE )
C ) The equation Ax = 0 has only the trivial solution ( TRUE )
D ) The columns of A form a linearly independent set ( TRUE )
Step-by-step explanation:
Assuming a matrix A
![\left[\begin{array}{ccc}1&2&1\\-1&0&3\\4&1&5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%262%261%5C%5C-1%260%263%5C%5C4%261%265%5Cend%7Barray%7D%5Cright%5D)
det A = 1 [ 0 -3 ] + 2 [12 + 5 ] + 1[-1]
= -3 + 34 -1 = 30 ≠ 0
THEREFORE det A = 30 ≠ 0
Attached is the detailed solution of the given statements above
1) 29.74*60=1,784.4 miles per minute
1,784.4= 1,784 4/10=
1,784 2/5 miles per minute
2) 29.74-8.23= 21.51=21 51/100
3) ???
4) 21.76*60=1,305.6=1,305 6/10
1,305 3/5
