Answer:
B
Step-by-step explanation:
A radius is half of a diameter so multiply by 2
Answer with Step-by-step explanation:
Suppose that a matrix has two inverses B and C
It is given that AB=I and AC=I
We have to prove that Inverse of matrix is unique
It means B=C
We know that
B=BI where I is identity matrix of any order in which number of rows is equal to number of columns of matrix B.
B=B(AC)
B=(BA)C
Using associative property of matrix
A (BC)=(AB)C
B=IC
Using BA=I
We know that C=IC
Therefore, B=C
Hence, Matrix A has unique inverse .
The ratio would be 4:6 because there are 6 number in total and 4 of them are odd numbers.
Answer:
4f + 6g -5
Step-by-step explanation:
4f - 3 +2g- - 4g + 2
4f - 3+ 2g + 4g - 2
4f -3-2 +2g +4g
4f -5 + 6g
4f + 6g -5
