What is the determinant of m= {5 8 -5 4} ? 20 40 60 80
likoan [24]

Answer:

60

Step-by-step explanation:

We have been given the matrix;

\left[\begin{array}{ccc}5&8\\-5&4\end{array}\right]

For a 2-by-2 matrix, the determinant is calculated as;

( product of elements in the leading diagonal) - (product of elements in the other diagonal)

determinant = ( 5*4) - (8*-5)

                     = 20 - (-40) = 60

We define a bow-tie quadrilateral as a quadrilateral where two sides cross each other. An example of a bow-tie quadrilateral is
aleksandrvk [35]

Answer:

70/5985

Step-by-step explanation:

We know that a quadrilateral needs to have four vertices (or points on the circle). There are always two ways to link the cross — horizontally or vertically. Using my limited knowledge of combinations, we know that choosing four points out of seven equals 35. Multiplying the two ways to connect those lines (again, horizontally and vertically) makes 35*2 = 70 "bow-tie quadrilaterals" that can be formed on the circle using four points. There are 5985 ways four chords can be chosen out of twenty-five chords because C(25,4) equals 5985, so the probability is 70/5985... and then we just need to simplify that fraction.

What is a differential equation
pickupchik [31]
A differential equation is one that contains the derivative of a function.  For example f(x) + 3 = 4f'(x) - 2.  Usually you will be given one of the functions and initial conditions if you have to solve.
