The determinant of the given matrix is 8+4xz-8y. Therefore, the determinant depends on the variable.

What is determinant?

Determinants are considered as a scaling factor of matrices. They can be considered as functions of stretching out and the shrinking in of the matrices. Determinants take a square matrix as the input and return a single number as its output.

The given matrix is


The determinant of 3×3 matrix can be find using

|C|= a₁(b₂c₃−b₃c₂)−b₁(a₂c₃−a₃c₂)+c₁(a₂b₃−a₃b₂)

Now, 1(2×4-z×0)-0(x×4-y×0)+4(x×z-y×2)

= 8+4xz-8y

The determinant of the given matrix is 8+4xz-8y. Therefore, the determinant depends on the variable.

det = 8

Step-by-step explanation:

1(8 - 0) - x(0 - 0) + y(0 - 0)

= 8

graces monthly sales totaled $1000. she earns $2000 plus 9% of her sales. what is her total paycheck for this month?


so 2000+9% of sales
percent means parts out of 100 so 9%=9/100=0.09
'of' means multiply
9% of sales=0.09 times 1000=90
so paychhec=2000+90=$2090

12 21 23 32 34 43 what is the next numbers


The next numbers in the sequence 12, 21, 23, 32, 34, 43, ..... are 45, 54, 56, .....

What is a sequence?

In Mathematics and Geometry, a sequence is a series of real and natural numbers in which each term or list of elements are ordered in a particular order and repetitions are allowed.

By critically observing the sequence, we can logically deduce that it represents an addition series in which both 9 and 2 are added alternatively to the sequence as follows;

12 + 9 = 21

21 + 2 = 23

23 + 9 = 32

32 + 2 = 34

34 + 9 = 43

43 + 2 = 45

45 + 9 = 54.

54 + 2 = 56.

after each number you had 11

so when you subtract

32-12 = 11

now add this 11 to 43

11+43 = 54

so the next numbers are 45 and 54

Which shape is ALWAYS a type of rectangle?


Square is always a type of rectangle! So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length.
