Answer: C
<u>Step-by-step explanation:</u>
Let x represent the first term (a₁)
a₁ = x
a₂ = x(-√2) = -x√2
a₃ = -x√2(-√2) = 2x
a₄ = 2x(-√2) = -2x√2
a₅ = -2x√2(-√2) = 4x
Since it is given the a₅ = √2, then we can solve: 4x =√2
Divide both sides by 4 to get: x = 
this can also be written as: 
Answer:
Two sets are called disjoint if they have no elements in common. For example:
The sets S = { 2, 4, 6, 8 } and T = { 1, 3, 5, 7 } are disjoint.
Another way to define disjoint sets is to say that their intersection is the empty set,
Two sets A and B are disjoint if A ∩ B = 0.
In the example above,
S ∩ T = ∅ because no number lies in both sets.
Step-by-step explanation:
180 - 149 = 31
x/100 *149 = 31
1.49x = 31
x= 31/1.46 = 20.81 %
Answer:
2y=52
Step-by-step explanation:
1st equation *(-3) and 2nd *(2)
-6x-10y=34
6x+12y=18
eliminate -6x and 6x
add both equations
2y=52
