What is the multiplicity of the root 2 in the equation x^3-8x^2+20x-16=0?
mote1985 [20]
Factoring the cubic you get: <span>(x - 2)^2 (x-4) , so we know the multiplicity is the amount of times a root shows in an equation because the equation (x-2) has a exponent of 2 that means the root 2 has a multiplicity of 2.</span>

How do I do this question
s344n2d4d5 [400]

The two laws of motion are

\text{Low:}\ d=v_lt\\\text{Sim:}\ d=v_st

Since Mr Sim's speed is 15 km/h less that Mr Low's, we have

\text{Low:}\ d=v_lt\\\text{Sim:}\ d=(v_l-15)t

Note that the distance d is the same for both equations, because they traveled the same path.

20 minutes is 1/3 of a hour, so at t=1/3 Mr Low traveled the whole distance, while at the same time Mr Sim traveled 4/5 of the distance:

\text{Low:}\ d=\dfrac{v_l}{3}\\\text{Sim:}\ \dfrac{4d}{5}=\dfrac{(v_l-15)}{3}

If we multiply Sim's equation by 5/4, we have

\text{Low:}\ d=\dfrac{v_l}{3}\\\text{Sim:}\ d=\dfrac{5(v_l-15)}{12}

Since the left hand sides are equal, we equal the right hand side as well:

\dfrac{v_l}{3}=\dfrac{5(v_l-15)}{12}

Multiply both sides by 12:

4v_l=5(v_l-15)

Expand the right hand side:

4v_l=5v_l-75 \iff v_l = 75

Which implies

v_s=v_l-15=75-15=60
