Answer:
28 ways
Step-by-step explanation:
After placing 1 ball in each of the seven bins, there are two balls left.
If we place both balls in a single bin, there are 7 different ways to place the balls (place both on bins 1 through 7).
If we place each of the remaining balls in a different bin, the number of ways to place the balls is:

The total number of ways to distribute those balls is 21 + 7 = 28 ways.
Answer:
Resistivity
Step-by-step explanation:
Resistivity : It is a fundamental property of a material that measures how strongly a particular material opposes the flow of electric current. It is also known as specific resistance.
- A low resistivity indicates a material that easily allows the flow of electric current.
- Resistivity is commonly represented by the Greek letter ρ (rho) or abbreviated with a a capital letter K. The SI unit of electrical resistivity is the ohm-metre (Ω⋅m).
Hence, the correct answer for the blank is Resistivity.
Answer: true false some true

Answer:
C. 
Step-by-step explanation:
Given: 
To find the domain of a logarithmic function, we need to take the argument, 8x, and set it greater to zero. This is because an argument of a logarithmic function cannot be zero or negative.


So since x is greater than zero, we have just found out our domain:
Interval Notation: (0, ∞)
Set Notation: {
}
Subsitute -4y for x
-4y+6y=18
2y=18
divide both sides by 2
y=9
sub back
x=-4y
x=-4(9)
x=-36
(x,y)
(9,-36)
