Evaluate the determinant of the matrix.<br> -4 5 6<br> 0 4 4<br> -2 -5 4<br> I need the work plz
FromTheMoon [43]

Answer:

-136

Step-by-step explanation:

We have to find the determinant of the following matrix:

\left[\begin{array}{ccc}-4&5&6\\0&4&4\\-2&-5&4\end{array}\right]

We can find the determinant by expanding via 1st column. i.e. by taking each element of 1st column and multiplying it by its co-factor matrix as shown below:

det \left[\begin{array}{ccc}-4&5&6\\0&4&4\\-2&-5&4\end{array}\right]

= (-4 \times det \left[\begin{array}{cc}4&4\\-5&4\end{array}\right]) - (0 \times (-4 \times det \left[\begin{array}{cc}5&6\\-5&4\end{array}\right]))+ ((-2) \times det\left[\begin{array}{cc}5&6\\4&4\end{array}\right])\\\\ =-4 \times (16 + 20)-(0)+(-2 \times 20-24)\\\\ =-4(36)+(-2(-4))\\\\ =-144+8\\\\ =-136

The notation det() stands for determinant of the matrix.

Therefore, the determinant of the given matrix is -136

Daryl is buying apples and bananas. He bought (a) pounds of apples that cost $2 per pound and (b) pounds of bananas that cost $1
Eva8 [605]

Expression 2a + b represents the situation (total cost) of buying a apples and b bananas.

<u> Solution: </u>

Given that  Daryl is buying apples and bananas.

He bought (a) pounds of apples that cost \$2 per pound.

He bought (b) pounds of bananas that cost \$1 per pound.

Need to write an expression which represents the situation.

Cost of 1 pound of apple = 2

\text { So cost of } a \text { pounds of apple }=a \mathrm{x} \text { Cost of } 1 \text { pound of apple }=a \mathrm{x} 2=2 a

Cost of 1 pound of banana =1

\text { So cost of } b \text { pounds of banana }=b \text { x Cost of } 1 \text { pound of banana }=b \times 1=b

Total cost of apples and banana = 2a + b  

Hence, the required expression is 2a + b.
