Answer:

Step-by-step explanation:

the graphic does not indicate any limitation in any form in any direction.

compared to a default y = x function this function is just shifted a bit. but that does not block x or y from "running" all the way from -infinity to +infinity.

the coordinates of a pentagon ABCDE are A(-5,4),B (1,4),C(1,-1), D(-2,-5) and E(-5,-1) what is the perimeter of the pentagon

kogti [31]

Perimeter is a continuous line forming the boundary of a closed geometrical figure. perimeter of a pentagon = AB+BC+CD+DE+EA (that is 5 sided figure)
so my plan is easy but effective, calculate all those distances using those coordinates with the aid of distance formular. then you add those distances algebraically .

A construction company can remove 5 1/4 metric tons of dirt from a construction site in 4 1/2 hours what is the unit rate in met

photoshop1234 [79]

Answer:

$unit\ rate=1.16\ tons\ per\ hour$

Step-by-step explanation:

Hello , I can help you with this

remember how to convert mixed numbers to decimal numbers

$a\frac{b}{c}=\frac{(a*c)+b}{c}$

Step one

convert into decimal numbers

$5\frac{1}{4}\ metric\ tons= \frac{(5*4)+1}{4}\ metric\ tons=\frac{21}{4}metric\ tons=5.25\ metric\ tons\\4\frac{1}{2}\ hours=\frac{(4*2)+1}{2}\ hours=\frac{9}{2}\ hours=4.5\ hours$

Step two

the unit rate in metric tons per hour is given by:

$unit\ rate=\frac{number\ of\ tons}{number\ of\ hours} \\$

put the values into the equation

Let

tons=5.25 metric tons

hours=4.5 hours

$unit\ rate=\frac{5.25\ tons}{4.5\ hours}\\unit\ rate=1.16\ tons\ per\ hour$

Have a good day
