If A is a 5 by 7 matrix, what is the maximum rank that A can have?

Mathematics
1 answer:
amm18123 years ago
3 0

Answer:

5

Step-by-step explanation:

Remember, the rank of a matrix is the number of pivots or number of rows different of zero in the echelon form of the matrix.

Then, if A is a matrix 5\times 7 the maximum number of pivots that can have is one by row, that is, 5.

Then the maximum rank that A can have is 5.

Two of the exterior angles of an n sided polygon are each of 60 and the remaining exterior angle are of each 24 find the value o
oksano4ka [1.4K]

Answer:

12 sides

Step-by-step explanation:

Given that :

Two of the exterior angles are = 60

The rest are each 24 ;

Find n, the number of sides of the polygon

The sum of the exterior angles of a polygon = 360

2 of the angles are 60° each ;

360 - (2 * 60)

360 - 120 = 240°

The remaining sides are 24° each ;

Hence, number of sides that are 24°

240° / 24° = 10 sides

Hence, total number of sides :

10 sides (14° each) + 2 sides (60° each)

10 + 2 = 12 sides
