Step-by-step explanation:
(a)
Using the definition given from the problem
Therefore it is true for intersection. Now for union, we have that
Therefore, for this case, it would be true that .
(b)
1 is not a set.
(c)
To begin with
Therefore
Now, given an element of it will belong to both sets, therefore it also belongs to , and you would have that
, therefore .
(d)
To begin with , therefore
Answer:
x= -2/3 y+4
Step-by-step explanation:
Let's solve for x.
3x+2y=12
Step 1: Add -2y to both sides.
3x+2y+−2y=12+−2y
3x=−2y+12
Step 2: Divide both sides by 3.
3x
3
=
−2y+12
3
Solution
Step 1
Write an expression for the area of sector
Where
θ = 52°
π = 3.14
r = 8cm
Step 2
Find the area of the sector after substitution of values into the formula above.
To the nearest tenth the area of the shaded sector of circle C = 29.0cm²
Option A ( 2 , 4 , 6 , 8) because domain are x values
A. Factor the numerator as a difference of squares:
c. As
, the contribution of the terms of degree less than 2 becomes negligible, which means we can write
e. Let's first rewrite the root terms with rational exponents:
Next we rationalize the numerator and denominator. We do so by recalling
In particular,
so we have
For
and
, we can simplify the first term:
So our limit becomes
