Answer : Dimension of column A is also be 4 whereas the two vector basis lie in R⁴.
The smallest possible dimension of Nul A would be zero.
Step-by-step explanation:
Since we have given that
A is matrix of 4 x 9 .
so, Number of rows = 4
Number of columns = 9
Nul A = 5
It means that Rank of A would be 9 - 5 =4
So, rank A = 4
Thus, dimension of column A is also be 4 whereas the four vector basis lie in R⁴.
So, dim Col A = 4
If A is 7 x 3 matrix.
So, we know that
rank A + dim (null A) = 3
so, it is possible to have rank A = 3 so the dim col A should be 3
Then the smallest possible dimension of Nul A would be zero.
Answer:
y=1/4x-4
Step-by-step explanation:
slope is 1/4 and the y intercept is -4
The answer to this is Babe
We have the function d, representing the distance from the ground of a person riding on a Ferris wheel:
If we consider the position of the person at t = 0, which is:
This position, for t = 0, will be the same position as when the argument of the sine function is equal to 2π, which is equivalent to one cycle of the wheel. Then, we can find the value of t:
Then, the wheel will repeat its position after t = 60 seconds.
Answer: 60 seconds.
