Answer:
438.97 cm²
Step-by-step explanation:
To find the surface area, we break up the figure into two pieces(blue and yellow) and then add them together.
SA = 2(w · l + h · l + h · w)
2 · (6 · 16 + 4 · 16 + 4 · 6)
368 cm²
70.97 cm² + 368 cm²
438.97 cm²
Answer with Step-by-step explanation:
We are given that
A and B are matrix.
A.We know that for two square matrix A and B
Then,
Therefore, it is true.
B. det A is the product of diagonal entries in A.
It is not true for all matrix.It is true for upper triangular matrix.
Hence, it is false.
C.
When is a factor of the characteristics polynomial of A then -5 is an eigenvalue of A not 5.
Hence, it is false.
D.An elementary row operation on A does not change the determinant.
It is true because when an elementary operation applied then the value of matrix A does not change.
