Answer:
Step-by-step explanation:
We have a piesewise function composed of three pieces. two line segments and one point.
The first line cuts at point (0,0) and ends at point (3, -1)
If we use these two points we can find the equation of the line.
The slope m is:
So the equation is:
As the line cuts in (0,0) then 
and the equation is:
The equation of the second line is:
Now we can find f(x) (although it is not necessary to find the equation of f(x) because we have its graph)
if 
; 
if 
; 
if 
.
The limit of f(x) when x tends to 3 from the left 
is the limit of the function when x approaches 3 from the left. If x approaches 3 from the left then 
. If then f(x) is given by the line . Then the limit is -1 as seen in the graph
Answer: c

3H+2C= 5.45
Step-by-step explanation:
Answer:
82.97cm^2
Step-by-step explanation:
Given data
Circumference= 131.88 centimeters
We want to find the area of 6/10 part of a circle
Firstly, let us find the area of the circle
We need to get the radius
C= 2πr
131.88= 2*3.142*r
131.88=6.284r
r= 131.88/6.284
r=20.98 cm
Area= πr^2
Area= 3.142*20.98^2
Area= 3.142*440.16
Area= 1382.98cm^2
Hence 6/10 of a 1382.98
=0.06*1382.98
=82.97cm^2
Answer:
a = 5
b = -4
c = -20
Step-by-step explanation:
Here, we want to express the given equation in the following form;
So we can have this as;
5x-4y-20 = 0
That means we have;
a as 5
b as -4
and c as -20
