Let a and b be 3 Ã 3 matrices with det(a) = 4 and det(b) = 5. find the value of (a) det(ab)

Georgia [21]

(a) |AB| = |A| |B| = -1 * 2 = -2.

(b) |B^5| = |B|^5 = 2^5 = 32. 

(c) Since A is 4 x 4, 
|2A| = 2^4 * |A| = 16 * -1 = -16. 

(d) Since determinants are invariant under transposition, 
|A^t A| = |A^t| |A| = |A| |A| = (-1)(-1) = 1. 

(e) |B^(-1) AB| = |B^(-1)| |A| |B| 
.....................= (1/|B|) |A| |B| 
.....................= |A| 
.....................= -1. 

I hope this helps!

Angle angle B is half the size of angle a the measure of angle C is equal to 1 less than 2 times the measure of angle B the sum

marishachu [46]

Answer: No, the angles cannot form a triangle.

Step-by-step explanation:

Angle angle B is half the size of angle A. This means that

A = 2B

The measure of angle C is equal to 1 less than 2 times the measure of angle B. This means that

C = 2B - 1

The sum of the angle A and angle B is 114. This means that

A+B = 114

Substituting A = 2B into (A+B = 114), it becomes

2B + B = 114

3B = 114

B = 114/3 = 38 degrees

A = 114 - 38 = 76

C = 2B - 1

C = 2×38 - 1 = 76 - 1

C = 75

Recall, sum of angles in a triangle is 180 degrees. This means that

A + B+ C = 180 degrees. T

Therefore, if we add add angle A, angle B and angle C, it becomes

76 + 38 + 75 = 189 degrees

The sum is more than the sum of the angles in a triangle. Therefore, the angles cannot form a triangle.
