What else can I help you with?
If two rows of a matrix are interchanged what is true of the resulting determinant?
The determinant will change sign.
Is a plane determined by two intersecting lines?
Yes.To help visualize, consider this:A 3-legged stool won't wobble on a flat surface (3 points of contact.)The minimum number of points to define two intersecting lines is where the point where the lines intersect, and another unique point on each line. (3 points total) This is represented by where the 3-leg stool touches the flat surface. The flat surface represents any determinant plane.If the lines did not intersect, you would require 4 separate points to define them. This is represented by 4-leg chairs, which by contrast often wobble (if only very slightly), since the extra point is not required to define the flat surface that it rests on (the determinant plane)In essence, 'a plane is determined by two intersecting lines' is the same as saying 'a plane is determined by three uniquepoints', which are, in both cases true.
If the ordered pair (3-2) satisfies one of the two linear equations in a system how can you tell whether the point satisfies the other equation of the system?
Substitute the values for the two variables in the second equation. If the resulting equation is true then the point satisfies the second equation and if not, it does not.
To find discriminant of a matrix?
Well, Im not sure if this is true for all matrices of all sizes, but for a 2x2 square matrix the discriminant is... dis(A) = tr(A)^2 - 4 det(A) The discriminant of matrix A is equal to the square of the trace of matrix A, minus four times the determinant of matrix A. I know this to be true for all 2x2 square matrice, but I have never seen any statement one way or the other for larger matrices. Thus, for matrix A = [ a, b; c, d ] tr(A) = a+d det(A) = ad-bc tr(A)^2 = a^2 + 2ad + d^2 4 det(A) = 4ad - 4bc dis(A) = a^2 - 2ad + 4bc + d^2
The diagonals of a rhombus are perpendicular to each other true or false?
True
If two rows of a matrix are interchanged what is true of the resulting determinant?
The determinant will change sign.
Is it true or false that the periodic table is divided into rows or columns?
It is true that periodic table is divided into rows and columns. The rows are called periods and columns are called groups.
True or false insert rows and columns from the shortcut menu?
That is true. There is an insert option on the shortcut menu which can allow you to insert rows and columns.
Is it true that When rows are inserted into a worksheet if rows that are shifted down include any formulas Excel adjusts the cell references to the new locations.?
Yes, that is true.
Is that the determinant of any matrix is equal to the product of their eigenvalues?
Yes, the determinant of a square matrix is equal to the product of its eigenvalues. This relationship holds true for both real and complex matrices and is a fundamental property in linear algebra. Specifically, if a matrix has ( n ) eigenvalues (counting algebraic multiplicities), the determinant can be expressed as the product of these eigenvalues.
Is it true that there seven are groups or rows in the periodic table?
Catfish
An Excel worksheet can contain up to 256 columns and 16384 rows. True or False?
True.
How are rows and columns identified?
Columns are up to down, while rows are from left to right. This is true on spreadsheets, paper balance sheets, etc. On spreadsheets, columns are identified with letters and rows are numbered.
Is it true a word table consist of rows and columns?
Yes. Tables in general are made up of rows and columns. If it is a database table it can be said to be made up of records which are rows and fields which are columns.
Where clause restricts rows prior to inclusion in a group calculation?
TRUE
Table is represented as a collection of rows and columns called datasheet?
true
Why the rows in kernel of maize are even in number not odd?
The assertion is not true.
