Answer:
-x² -2x -5 -12/(x-2)
Step-by-step explanation:
The attachment shows the synthetic division. You can find the remainder by evaluating the dividend for x=2:
-2³ -2 -2 = -12 . . . . matches the above answer, not [A] or [C] shown
_____
You can always multiply out your answer to see if it matches the problem.
(-x^2 -2x +3)(x -2) +3 = -x^3 +7x -3 . . . . not the dividend you started with
Answer:
10
Step-by-step explanation:
use distributive property
-5*-2
negative plus a negative gives you a positive
10

The shape of the water is that of a "spherical cap." The formula for the volume of a spherical cap is ...
... V = π·h²·(r -h/3) . . . . . . . from web search
For a radius of 5 in, this is
... V = π·h²·(5 -h/3) . . . . in³
_____
For h=0
... V = π·0²·(5 -0/3) = 0
For h=5 in
... V = π·(5 in)²·((5 -5/3) in) = (2/3)π·5³ in³ . . . . . the volume of a hemisphere of radius 5
Answer:
since base is pi r^2
it's given that h=4r
now find derivative
× dr/dt
r=8 , dv/dt = 3
dv/dt = 4pi (8)^2 ×3 = 768pi
