So each foot is 12 inches so to remove 8 feet to get 12 in you need to remove 8 times 12 inches total or 96 in and each cut removes 1/8 in so times 96 by 8 and get 768 total cuts

Answer:
True
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (- 4, - 9), thus
y = a(x + 4)² - 9
To find a substitute the coordinates of the zero (- 7, 0) into the equation.
0 = a(- 7 + 4)² - 9, that is
0 = 9a - 9 ( add 9 to both sides )
9a = 9 ( divide both sides by 9 )
a = 1, thus
y = (x + 4)² - 9 ← expand factor using FOIL
y = x² + 8x + 16 - 9
y = x² + 8x + 7
What we need to do is divide 18 by 8 because 18 cups of flour makes 8 loaves of bread. By using a calculator, 18/8 = 2 1/4.
#8).
The volume of a cone is (1/3) (pi) (radius of the round end)² (height)
That's the volume of the ice cream cone alone.
The volume of a sphere is (4/3) (pi) (radius)³
The glob of ice cream on top is 1/2 of a sphere.
The sphere and the cone in this problem both have the same radius.
#9).
The volume of a cylinder is (pi) (radius of the round end)² (height)
#10).
Another cylinder !
The volume of a cylinder is (pi) (radius of the round end)² (height)
