Answer:
you will get speed on a slope and you will get speed with speed (:
Step-by-step explanation:
Answer:
the order is
2,4,1,3
(the 1st answer is the 2nd option)
The axis of symmetry can be found by finding the average of the zeros, a derivation from the conservation of energy :P, or by finding the point when the velocity is equal to zero.
df/dx=-6x+12 so df/dx, velocity, equals zero when:
-6x+12=0
6x=12
x=2 so the axis of symmetry is the vertical line x=2
....
average of zeros...
3x^2-12x+6=0
x^2-4x+2=0
x^2-4x=-2
x^2-4x+4=2
(x-2)^2=2
x-2=±√2
x=2±√2 so the average of the zeros is obviously 2.
....
conservation of energy
vf-vi=at When vf=0, this is the maximum value for f(x)...
-vi=at, vi=b and a(acceleration)=2a(from quadratic) and t=x
-b=2ax
x=-b/(2a) in this case
x=-12/(2(-3))
x=-12/-6
x=2
Answer:
the bottom one 42.061
upper one 49/2pi = 76.969
Step-by-step explanation:
the bottom one
14^2 - 49pi = 42.061
upper one, put the shaded parts together and that forms a semicircle
49/2pi = 76.969
