Answer:
The last one
Step-by-step explanation:
Answer:
my answer for y is -6, x is -10
Step-by-step explanation:
just eliminate the -4s by subtracting them and you will get the value of y.
now you can use either eqn (I) or (ii) which are first and second.
anyone you decide to choose just replace y by the value you got and you will get the value of x.
pls try to do it buddy you can
Note that f(x) as given is <em>not</em> invertible. By definition of inverse function,
which is a cubic polynomial in 
with three distinct roots, so we could have three possible inverses, each valid over a subset of the domain of f(x).
Choose one of these inverses by restricting the domain of f(x) accordingly. Since a polynomial is monotonic between its extrema, we can determine where f(x) has its critical/turning points, then split the real line at these points.
f'(x) = 3x² - 1 = 0 ⇒ x = ±1/√3
So, we have three subsets over which f(x) can be considered invertible.
• (-∞, -1/√3)
• (-1/√3, 1/√3)
• (1/√3, ∞)
By the inverse function theorem,
where f(a) = b.
Solve f(x) = 2 for x :
x³ - x + 2 = 2
x³ - x = 0
x (x² - 1) = 0
x (x - 1) (x + 1) = 0
x = 0 or x = 1 or x = -1
Then 
can be one of
• 1/f'(-1) = 1/2, if we restrict to (-∞, -1/√3);
• 1/f'(0) = -1, if we restrict to (-1/√3, 1/√3); or
• 1/f'(1) = 1/2, if we restrict to (1/√3, ∞)
Answer:
2: 6+4+6= 16
3: 6+6+9+9+18=48
4: 6+2+12+3+8= 36
I really hope this helped I’m not very Experienced in this.
Answer: pool B has a greater circumference.
Step-by-step explanation:
The formula for determining the circumference if a circle is expressed as
Circumference = 2πr
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Pool A has a radius of 48 feet.
1 foot ≈ 0.305 meters
48 feet = 48 × 0.305 = 14.64 meters
The circumference of pool A is
2 × 3.14 × 14.64 = 91.94 meters
Pool B has a diameter of 29.46 meters. Radius = diameter/2
Radius of pool B = 29.46/2 = 14.73 meters
The circumference of pool B is
2 × 3.14 × 14.73 = 92.5 meters
Therefore, pool B has a greater circumference.
