63^2+b^2=87^2
3969+b^2=7569
-3969 both sides
B^2=3600
Square root both sides

If D is an n × n diagonal matrix with entries dii, then det D = d11d22 ∙ ∙ ∙ dnn. Verify this theorem for 2 × 2 matrices.
nadya68 [22]

Answer:

Verified

Step-by-step explanation:

Let the diagonal matrix D with size 2x2 be in the form of

\left[\begin{array}{cc}a&0\\0&d\end{array}\right]

Then the determinant of matrix D would be

det(D) = a*d - 0*0 = ad

This is the product of the matrix's diagonal numbers

So the theorem is true for 2x2 matrices

Find the system of inequalities representing the given situation?
Diano4ka-milaya [45]

<u>The question was written by the student in a comment because the image contains no question at all.</u>

  • <u>Kathy sells candles for $3 and flowers for $5. She plans to sell at least 200 items and likes to earn a minimum of $2500. </u>

Answer:

\left\{\begin{matrix}x + y = 200\\ 3x + 5y = 2500\end{matrix}\right

Step-by-step explanation:

<u>System of equations</u>

Kathy sells candles for $3 and flowers for $5. Let's set the following variables:

x = number of candles Kathy sells

y = number of flowers Kathy sells

She plans to sell 200 items, thus:

x + y = 200

She also likes to earn $2,500. The equation for this condition is:

3x + 5y = 2500

The system of equations is

\left\{\begin{matrix}x + y = 200\\ 3x + 5y = 2500\end{matrix}\right
