Step-by-step explanation:
To prove it we just use the definition of similar matrices and properties of determinants:
If are similar matrices, then there is an invertible matrix , such that (that's the definition of matrices being similar). And so we compute the determinant of such matrix to get:
(Determinant of a product of matrices is the product of their determinants, and the determinant of is just )
B is yes and the rest are no. B is the only solution where y equals 1.

Answer:
26.13 cm
Step-by-step explanation:
Arc length (A) = (Θ/ 360) x (2 x π x r)
120/360=0.33
2 x π x 12.6=79.17
0.33 x 79.17=26.13 cm
Hello there!
(3.6)^x = 45
We wanna start by taking log of both sides.
log(3.6)^x = log(45)
x * (log(3.6))= log (45)
x = log(45)/log(3.6)
x = 2.971787
Thus, the correct answer is x = 2.97
I hope this helps!
