Answer:
Step-by-step explanation:
21% more then 5/11...
5/11 + 21% of 5/11 = 5/11 + 0.21(5/11) = 5/11 + (21/100 * 5/11) =
5/11 + 21/220 = 11/20 <===
Answer:
Five
Step-by-step explanation:
Pivot columns are said to be columns where pivot exist and a pivot exist in the first nonzero entry of each row in a matrix that is in a shape resulting from a Gaussian elimination.
Suppose A = 5 × 7 matrix
So; if A columns span set of real numbers R⁵
The number of pivot columns that A must have must be present in each row. In a 5 × 7 matrix ; we have 5 rows and 7 columns . So , since A must be present in each row, then :
The matrix must have five pivot columns and we can infer that about the statements that "A has a pivot position in every row" and "the columns of A spans R⁵" are logically equivalent.

Answer:
x = 2k is the solution of this equation.
Step-by-step explanation:
This question is related to trigonometric equations.
The given equation is,
We have to find the solutions of this equation.
Put
+ 3cosx - 1 = 2
= 0
For this equation only cosx = 1 is possible solution.
Cosx = 1 happens when x is a multiple of 2
So x = 2k is the solution of this equation.
