Answer:
OD) 4000
Step-by-step explanation:
Volume of a pentagonal pyramid = Area of base x height
Since every dimension is multiplied by 5,
Area is multiplied by 5² and height by 5
So volume is multiplied by 5^3 = 125
The volume = 125 x 32 = 4000
Answer:
1) a. False, adding a multiple of one column to another does not change the value of the determinant.
2) d. True, column-equivalent matrices are matrices that can be obtained from each other by performing elementary column operations on the other.
Step-by-step explanation:
1) If the multiple of one column of a matrix A is added to another to form matrix B then we get: |A| = |B|. Here, the value of the determinant does not change. The correct option is A
a. False, adding a multiple of one column to another does not change the value of the determinant.
2) Two matrices can be column-equivalent when one matrix is changed to the other using a sequence of elementary column operations. Correc option is d.
d. True, column-equivalent matrices are matrices that can be obtained from each other by performing elementary column operations on the other.
The red marbles are caused by the geometry and the statistics the amount of red barbels in the bag is 25
This is what you do.
(3)^(-9+7)= (3)^(-2)
= (1/3)^2
=1/9
I think the answer is C ( 11 )
