Answer:
x = - 5/2 or x = - 3/2
Step-by-step explanation:
|-2(x+2|=1
|-2x-4|=1
- 2x - 4 = 1 or - 2x - 4 = - 1
- 2x - 4 = 1
- 2x = 4+1
x = - 5/2
or -2x - 4 = - 1
-2x = 4 - 1
x = - 3/2
Answer:
y=2/7x+34/7
Step-by-step explanation:
the slope of this line is 2/7.
y=2/7x+?
? is the y-intercept.
Looking at the line that we have graphed, we can see that it intersects at 34/7 y.
the equation for the line that goes through 4,6 and -10, 2 is
y=2/7x + 34/7
Volume of a Cylinder (Drum) = πr²h
Substitute the known values,
v = 3.14 * (1.2)² * 4
v = 18.09 Ft³
Now, price for 1 Ft³ = $22
So, for 18.09 Ft³ would be: 22 * 18.09 = $397.9
In short, Your Answer would be: $397.9
Hope this helps!
Answer:
81y^2+36y+4
Step-by-step explanation:
First: 9y^2= 81y
Next: 2^2= 4
Then: 9y times 2= 18
Last: 18 times 2= 36y
(this : ^2 means squared in case you did not know)
The height of the can for this case is given by:
h = 40 mm
The radius of the can is given by:
r = (1 3/8) * h
Substituting values:
r = (1 3/8) * 40
r = 55 mm
Therefore, the diameter of the can is:
d = 2 * r
d = 2 * 55
d = 110 mm
Answer:
The diameter of the can will be:
d = 110 mm
