Answer:
really hard
Step-by-step explanation:
ask sheldon
Domain- [-6, infinite)
Range: [0, Infinite)
This is because you get the x from the square root (-6) and the y from the invisible 0. Because it doesn’t have a negative x, it goes up.
First you would have to do V=bh to the power of 2
B= base
H= height
Base= 62
Height. 10
Its a triangle right? So you have to divide by 2
Now its V=2bh
V=2(62)(10)
62
x62
------
3844x10=38440 divide by 2
Then that should be your answer please tell me if im wrong i would love the suport
Btw this is all by memory Thanks!

Answer:
0, 1, 2
Step-by-step explanation:
It is an absolute value function which means that every y value has 2 X values besides 0
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).
