Number of faces + (Number of vertices - Number of edges) = 2
So plugging in the numbers it would then be
18+(12-30)=2
18-18=2
0=2
Kelvin would be wrong and I disagree with him. (Because ...*plugin work cited above*)
Answer:
x=0, x= - 3, x=9
Step-by-step explanation:
f(x)=7/2x(x+3)(x-9)
f(x) doesn't exist for x=0,-3,9
as
vertical asymptote:
x=0, x= - 3, x=9
Answer:
$5277.88
Step-by-step explanation:
We want to find what the measure of the outside of the garden is
We can use circumference, because it is the distance around the edge of a circle
The circumference formula is:
c= 2r
Substitute 70 in for r(radius)
c= 2*70
c= 140
c=439.822971503 meters
Now to find the cost
Multiply the cost of fencing per meter by the circumference
439.822971503*12=5277.87565803
The fencing will cost about $5277.88
Answer:
<u>[x - (4 + 2√3)] and [x - (4 - 2√3)]</u>
Step-by-step explanation:
Given :
Divide throughout by 3 to simplify :
- 1/3 x (3x² - 24x + 12)
- x² - 8x + 4
Using the Quadratic Formula :
- x = -b ± √b² - 4ac / 2a
- x = -(-8) ± √(-8)² - 4(1)(4) / 2(1)
- x = 8 ± √64 - 16 / 2
- x = 8 ± √48 / 2
- x = 8 ± 4√3 / 2
- x = 4 ± 2√3
Factors are :
- <u>[x - (4 + 2√3)] and [x - (4 - 2√3)]</u>
Answer:
1/6
Step-by-step explanation:
because there is only one number 3 there is a 1/6 chance of you getting a 3
