Consider this option:
Volume is 256π/5, area is 32/3.
Details are in the attachment.
P.S. intersection points are (-2;4) and (2;4).
Answer:
f(x) = 2π (11 + sin x) √(1 + cos²x)
Step-by-step explanation:
Surface area of a curve rotated about y = a is:
S = ∫ 2π (y − a) ds,
where ds = √(1 + (dy/dx)²) dx.
y = 6 + sin x, and a = -5. dy/dx = cos x. Plugging in:
S = ∫₀²ᵖⁱ 2π (6 + sin x − -5) √(1 + cos²x) dx
S = ∫₀²ᵖⁱ 2π (11 + sin x) √(1 + cos²x) dx
Therefore, f(x) = 2π (11 + sin x) √(1 + cos²x).
Answer:
I think that it is 9 and 10 because when you simply the number 85 it would be 9.21 which is round by 9
.45 is between 0.4 and 0.5
Answer:
Infinitely many solutions.
Step-by-step explanation:
3x-3y=6
-6x+6y=-12
------------------
2(3x-3y)=2(6)
-6x+6y=-12
-------------------
6x-6y=12
-6x+6y=-12
--------------------
0=0
