If A is an n× n matrix, then det A = det AT . Verify this theorem for 2 × 2 matrices.

Bond [772]

Answer:

Verified

Step-by-step explanation:

Let A matrix be in the form of

$\left[\begin{array}{cc}a&b\\c&d\end{array}\right]$

Then det(A) = ad - bc

Matrix A transposed would be in the form of:

$\left[\begin{array}{cc}a&c\\b&d\end{array}\right]$

Where we can also calculate its determinant:

det(AT) = ad - bc = det(A)

So the determinant of the nxn matrix is the same as its transposed version for 2x2 matrices

Suppose you invest $500 in a savings account that pays 3.5% annual interest.

icang [17]

That would be exponential growth.

Total = principal * (1+rate)^time

Total = 500 * (1+.035)^5

Total = 593.84
