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

half of an orange juice mixture is orange concentrate. explain why the ratio of orange concentrate to water 1:1

mars1129 [50]

Answer:

Please read below

Step-by-step explanation:

We are told that 1/2 of the orange juice is concentrate

So 50% is concentrate

100 - 50 = 50

This leaves another 50% to be water
50:50 is the same as 1:1

Let the following sets be given. The universal set for this problem is the set of all students at some university. F = the set o

stepan [7]

Answer:

|M'∩F| > |S∩C|

Step-by-step explanation:

<h3 /><h3>The situation is depicted in the picture attached </h3>

The green set is

M'∩F = freshmen who aren't math majors and it has |M'∩F| elements

The blue set is

S∩C = senior CS majors and it has |S∩C| elements.

So <em>“There are more freshmen who aren't math majors than there are senior CS majors”</em> can be written as

|M'∩F| > |S∩C|
