Yes because if you add up all his expenses $92.87+$11.29+$20.00=124.16 which leaves $104.84 (229-124.16=104.84) left and the X-box game only costs $54.99
Answer:
True, if with distinct you refer with multiplicity 1.
Step-by-step explanation:
The answer is true, assuming that the matrix has as many distinct eigenvalues than the number of rows and columns of the matrix (we can suppose that with distinct you mean that the multiplicity for each eigenvalue is 1).
Lets suppose that the matrix has size n, and let λ1, λ2, λ3, ..., λn be its eigenvalues. Each eigenvalue has an eigenvector vi such that Avi = λivi.
A matrix C whose columns are those eigenvectors v1...v1, will satisfy that the product A*C is the square matrix of length n with columns λ1v1, λ2v2, ..., λnvn. Hence C⁻¹AC = C⁻¹ * (AC) will be a diagonal matrix (because the columns of AC are multiples of the columns of C, which is the inverse of C⁻¹). This shows that C⁻¹AC = C⁻¹ is a diagonal matrix D, then A = CDC⁻1.
THe answer is -7+1i.
I just did the assignment as well, hope this helps!
Answer:
211
Step-by-step explanation:
As the statement indicates that on each of the 22 work days of the month the employees of the company received a communication and 4642 communications were sent, to be able to determine the number of employees that the company have, you have to divide the number of communications by the number of days:
4642/22= 211
The company has 211 employees.
