Answer:
Label theta as the missing length. You are solving circle segment so use the formula
Area of Segment = θ − sin(θ)2 × r2 (when θ is in radians)
Area of Segment = ( θ × π360 − sin(θ)2 ) × r2 (when θ is in degrees)
So the answer would be 7.68

Answer:
3 or 4, I am confused
Step-by-step explanation:
I'll assume that f(x) = x2 – 2x + 8 is meant to be f(x) = x^2 – 2x + 8
Find the value of f(x) for x = 2:
f(x) = x^2 – 2x + 8
f(2) = (2)^2 – 2*(2) + 8
f(2) = 4 - 4 + 8
f(2) = 8
=============
From the graph, we can find that g(2) = 11
The differece between g(2) and f(2) is thus:
11 - 8 = 3
3 is not an option, so I wonder if the question is asking for the difference between the absolute maximum of g(x) and f(2). If so, the maximum for g(x) is 12, at x = 3.
This would lead to a difference of 12 - 8, or 4. This is still not an option, so I'm confused. Perhaps you can find my error and find the ciorrect answer, or at least one that appears in the options.
Step-by-step explanation:
Area of a circle is:
A = πr²
Take derivative with respect to time:
dA/dt = 2πr dr/dt
Plug in values and solve:
-5 = 2π (2) dr/dt
dr/dt = -5/(4π)
dr/dt ≈ -0.398
The radius is shrinking at approximately 0.398 in/min.
16x + 64
Hope this helps:)
