Prove the theorem (AB )^T= B^T. A^T
Lisa [10]

Answer:

(AB)^T = B^T.A^T  (Proved)

Step-by-step explanation:

Given  (AB )^T= B^T. A^T;

To prove this expression, we need to apply multiplication law, power law and division law of indices respectively, as shown below.

(AB)^T = B^T.A^T\\\\Start, from \ Right \ hand \ side\\\\B^T.A^T = \frac{B^T.A^T}{A^T}.\frac{B^T.A^T}{B^T} (multiply \ through) \\\\                = \frac{A^{2T}.B^{2T}}{A^T.B^T} \\\\=\frac{(AB)^{2T}}{(AB)^T} \ \ (factor \ out \ the power)\\\\= (AB)^{2T-T}  \ (apply \ division \ law \ of \ indices; \ \frac{x^a}{x^b} = x^{a-b})\\\\= (AB)^T \ (Proved)

2. Angelika wants to invest $6000 in a hot new stock
Ne4ueva [31]

Answer:

Option B, trade with an app that charges a flat brokerage

fee of $3 per trade.

Step-by-step explanation:

1) In option A, the broker charges 2% brokerage. This means that 2% of the money invested goes to the broker. Since Angelika wants to invest $6000, the amount of money to be charged by the broker = 2% of $6000 = 0.02 * $6000 = $120

2) Option B uses an app that charges a flat brokerage of $3 per trade. This means that for any transaction, the money to be charged would be $3. Since Angelika wants to invest $6000, the amount of money to be charged by the broker = $3
