Answer:
= m
Step-by-step explanation:
So we can say;
Tan(30) = m/3
=> Tan(30) * 3 = m
=> = m
Hope this helps!
Answer:
Step-by-step explanation:
compare with that y=mx+c
where m=slope .
So after comparing we get m=
As the lines are perpendicular
therefore m2=
Now from the equation
this equation passing to the point (-5,5) with m=
Therefore equation is
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:
You use the pythagorean theorem given three angles in number two as it is a 30, 60, 90 triangle . The first one is a 60, 90 and a side and the third is a 60, 90 and a side as well. You should be able to find the equations for this easily enough.
Step-by-step explanation:
Answer:
Step-by-step explanation:
B. m<QLP = 50° (True)
C. m<NLO + m<OLP = m<NLP (True)
30° + 40° = 70°
D. m<QLP + m<PLO = m<MLN + m<NLO (True)
50° + 40° = 60° + 30°
