To find the combined volume, you will find the volume of each figure separately and then add them together. You will use the formulas for each polyhedra (3-D) shape.
V = 1/3 Bh (pyramid); B stands for the area of the base of the figure
V = 1/3 x 8 x 8 x 3
V = 64 cubic inches
V = Bh (prism)
8 x 8 x 4
V = 256 cubic inches
256 + 64 = 320 cubic inches
The total volume of the box is 320 cubic inches.
Divide both sides over 2pi
r = c/2pi
60/15=4 meaning 25% of the dogs are purebreed
Answer:
See below
Step-by-step explanation:
The given rational function is;

The given function is not continuous where the denominator is equal to zero.

The function is discontinuous at 
b) The point at x=-2 is a removable discontinuity(hole) because (x+2) is common to both the numerator and the denominator.
The point at x=-4 and x=4 are non-removable discontinuities(vertical asymptotes)
c) The equation of the vertical asymptotes are x=-4 and x=4
To find the equation of the horizontal asymptote, we take limit to infinity.

The horizontal asymptote is y=0
