staircase of steps in a swimming pool has a vertical rise of 14 inches per step and a landing of 20 inches.
Jlenok [28]
I think the question for this problem is to find the slope of the staircase. The slope is a ratio of change of the y-coordinates and x-coordinates of points. It is written as Δy/Δx especially in analytical geometry. It could also be simply the ratio of the rise or vertical height to the run or horizontal length.

Therefore, the slope of the stair case is

Slope = rise/run = 14/20 = 0.7

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
