Alchen [17]
The denominator :  q² - 3q - 4 should be ≠ 0.
Let's find the zero values of this quadratic equation:

q' = [-b+√(b²-4.a.c)]/2.a    and   q'' = [-b-√(b<span>²-4.a.c)]/2.a

you will fond q' = 4  and q'' = -1

Then the restrictions are :

q </span>≠ 4 and q ≠ - 1 (1st answer)

What is the slope of the segment shown for a staircase with 10-inch treads and 7.75-inch risers? As you walk up (or down) the st
s2008m [1.1K]

The formula for slope is

Slope = Rise / Run = Risers / Treads

Slope = 7.75 in /10 in = 0.775

The slope Is 0.775.

The vertical distance is not continuous, thus it is discrete. A discrete function only allows certain points in the interval. When you walk up or down the stairs, the vertical distances are not continuous because of the treads. You cannot stay also mid-air, so it should be discrete. An example of a continuous function would be when you walk up or down an inclined plane.
