Answer:
The question can be answered by using a Pythagoras' Theorem : to find the base of the pole to which each wire is attached to the ground.
Step-by-step explanation:
the base of the pole is represented by b.
the height of the pole is represented by a= 5 feet
the length of t he wire is represented by c=5 feet.
Thus, using the Phytagoras Theorem,
c^2=a^2+b^2,
or b=3.3.
Thus , each wire i attached by about 3.3 feet to the base of the pole.
Answer:
3.32ft
Step-by-step explanation:
The wire and the poles attached to the ground form a right triangle with the length of the wire being the hypotenuse.
Using Pythagoras Theorem:
Hypotenuse²=Adjacent²+Opposite²
6²=5²+x²
x²=36-25
x²=11
x=√11=3.32 ft.
The wires are attached 3.32 ft from the base of the pole on the ground

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.
