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.

14.75x - 2.3 = 5.25x + 45.2

Cerrena [4.2K]

14.75x - 23=5.25x+45.2
14.75x-23-5.25x=5.25x+45.2-5.25x
14.75-5.25x=9.5
9.5x-23=45.2
9.5x-23+23=45.2+23
9.5x=68.2
9.5x/9.5=68.2/9.5
x=7.178947

Chin made an error in his chart showing the multiplication of the binomial by the trinomial. Which change can be made to correct

Tcecarenko [31]

Answer:

The expression 6x should be 6x²

Step-by-step-explanation:

The chart being referred to showing the multiplication of the binomial by the trinomial is given in the attached picture below.

To find out where Chin made an error in his multiplication, and also determine the right expression, let's take a look at each multiplication done. Thus we have:

3x*x² = 3x³

3x*2x = 6x² (here is where the error was made, in the chart, Chin wrote 6x)

3x*4 = 12x

2*x²=2x²

2*2x = 4x

2*4 = 8

Therefore, the expression 6x should be 6x²
