Step-by-step explanation:
Find out the equation of each line of the piece wise
<em>First line</em>
The first line has an open circle at (negative 2, negative 2) and it continues horizontally to an open circle (negative 5, negative 2)
(-2,-2) to (-5,-2)


<em>Second line</em>
The second line has a closed circle at (negative 2, 0) and then continues up to an open circle at (1, 1.5)
[-2,0] to (1,1.5)
<u><em>Find the slope</em></u>

<u><em>Equation in point slope form</em></u>

we have


substitute

<u><em>Convert to slope intercept form</em></u>

so


<em>Third line</em>
The third line has a closed circle at (1, 4) and continues down to open circle (5, negative 4). Which functions represent a piece of the function?
[1,4] to (5,-4)
The equation of the line is
---> Repeat all steps that in second line

therefore
The piece wise function is equal to
----> 
----> 
---> 
Answer:
0.7

Step-by-step explanation:
circumference of jj's basketball = 29.6 inches
Circumference of basket = 3.14 * 10 = 31.4 inches
Because
circumference of jj's basketball < Circumference of basket
Therefore ball will go through the basket.
Step-by-step explanation:
look at the picture !
she has to paint actually 6 rectangles :
the 3 tops of the 3 stairs.
and the 3 vertical front boards (the front of each step of the stairs).
what is the area of these rectangles ? summing up all 6 - that is the surface area to be painted.
each top rectangle is clearly
82×19 (19 cm deep) = 1558 cm²
each front board is
82×12 (12 cm high) = 984 cm²
so, in total we have
3×1558 + 3×984 = 4674 + 2952 = 7626 cm²
as surface area to be painted.
