A parabola with an equation, y2 = 4ax has its vertex at the origin and opens to the right.
It's not just the '4' that is important, it's '4a' that matters.
This type of parabola has a directrix at x = -a, and a focus at (a, 0). By writing the equation as it is, the position of the directrix and focus are readily identifiable.
For example, y2 = 2.4x doesn't say a great deal. Re-writing the equation of the parabola as y2 = 4*(0.6)x tells us immediately that the directrix is at x = -0.6 and the focus is at (0.6, 0)
think the answer is
x=6+sqrt0/2 x=6-sqrt0/2 both equaling into 3.
But I might be wrong.
Answer:
370 peanuts
Step-by-step explanation:
65/108 = 0.60185
90/150 = 0.6000
In each case, the number of peanuts is either exactly or very close to 60% of the volume.
A cylinder with radius 3.5 cm and height 16 cm has volume:
V = (pi)r^2h
V = (3.14159)(3.5 cm)^2(16 cm)
V = 615.752 cm^3
We take 60% of the volume to estimate the number of peanuts.
60% * 615.752 cm^3 = 369.451
Answer: 370 peanuts
I believe the answer to be 45
Hope this helps you
