3. Classify the polygon below by its sides,
convex/concave, and regular/irregular

The polygon is a concave polygon

The polygon is irregular polygon

Step-by-step explanation:

Convex polygon is polygon that has all interior angles less than 180°

In a convex polygon, every diagonal of the figure passes only through interior points of the polygon

A line drawn through a convex polygon will intersect the polygon in exactly two points

Some of convex polygons can be regular polygons

Concave polygon is a polygon that has one or more interior angles greater than 180°

In a concave polygon, at least one diagonal of the figure contains points that are exterior to the polygon

A line drawn through a concave polygon, can intersect the polygon in more than two points

Concave polygon never be a regular polygon

From the attached figure

∵ The polygon has one diagonal lies out the interior of the polygon

∴ The polygon is a concave polygon

∵ All the concave polygons are regular polygons

∴ The polygon is irregular polygon

the data of the miami heat in numerical order from least to greatest is 0.50, 0.50, 0.56, 0.57, 0.67, 0.72, 0.72, 0.72, 0.75, 0.75, 0.76, 0.81, 0.82, 0.90, 1.00, 1.00

the detroit pistons median : 1.52

the miami heat median: 1.47

the iqr of this data is 0.05

a.   we have two

lines:   y = 4-x   and  

y = 8-x^-1

given two simultaneous equations that are both to be

true, then the solution is the points where the lines cross. the intersection is

where the two equations are equal. therefore the solution that works for both

equations is when

4-x = 8-x^-1

this is where the two lines will cross and that is the

common point that satisfies both equations.

b.   4-x = 8-x^-1

  x           4-x       8-x^-1

-3           7        

8.33

-2           6         8.5

-1           5         9

  0           4        

-

  1           3        

7

  2           2        

7.5

  3           1         7.67

the table shows that none of the x values from -3 to 3 is

the solution because in no case does

4-x = 8-x^-1

to find the solution we need to rearrange the equation to

find for x:

4-x = 8-x^-1

multiply both sides with x:

4x-x^2 = 8x-1

x^2+4x-1=0

x= -4.236, 0.236

therefore there are two points that satisfies the

equation.

find y:  

x=-4.236

y = 4-x   = 4 – (-4.236)

= 8.236

y = 8-x^-1 =   .236)^-1

= 8.236

x=0.236

  y = 4-x   = 4 – (0.236) = 3.764

y = 8-x^-1 =   8-(0.236)^-1

= 3.764

thus the two lines cross at 2 points:

(-4.236, 8.236) & (0.236, 3.764)

c.   to solve

graphically the equation 4-x = 8-x^-1

we would graph both lines: y = 4-x   and   y

= 8-x^-1

the point on the graph where the lines cross is the

solution to the system of equations.

just graph the points on part b on a cartesian coordinate

system and extend the two lines.   the

solution is, as stated, the point where the two lines cross on the graph.
