Answer:
The graph in the attached figure
Step-by-step explanation:
we have
1)
-----> For the interval (-∞,-1)
Note The value of x=-1 is a open circle ( is not included)
This is a vertical parabola open upward
The vertex is a minimum
The vertex is the point (-2,0)
2)
----> For the interval [-1,1]
Note The value of x=-1 and x=1 are closed circle ( both values are included)
This is an absolute function open upward
The vertex is the point (0,1)
3)
-----> For the interval (1,∞)
Note The value of x=1 is a open circle ( is not included)
The value of f(x) is negative for all values of x
therefore
The graph in the attached figure
Answer:
396 pi
Step-by-step explanation:
equation is A = pi r squared times height
Get into y=mx+b form
m=slope
3x-5y=10
minus 3x from both sides
-5y=-3x+10
divide both sides by -5
y=-3/-5x+10/-5
y=3/5x-2
the slope is 3/5
Answer:
70
Step-by-step explanation:
9/100=0.09
9-2.7=6.3
6.3/0.09=70
Answer:
40%
Step-by-step explanation:
14-10 = 4, which is a 4 euro increase.
4/10 = 40%
Or we can see that 14/10 = 1.4, or 140%, which is a 40% increase
