Hi,
f(1)=2*1^5-9*1^4+12*1^3-12*1^2+10*1-3\\
=2-9+12-12+10-3\\
=0\\

f(x)=(x-1)(2x^4-7x^3+5x^2-7x+3)\\


g(x)=2x^4-7x^3+5x^2-7x+3\\

g(3)=2*3^4-7*3^3+5*3^2-7*3+3\\
=162-189+45-21+3\\
=0\\

g(x)=(x-3)(2x^3-x^2+2x-1)\\

h(x)=2x^3-x^2+2x-1\\

h( \dfrac{1}{2} )=2* \dfrac{1}{8} - \dfrac{1} {4}+1-1\\
=0\\

h(x)=(2x-1)(x^2+1)\\


f(x)=(x-1)(x-3)(2x-1)(x+i)(x-i)\\



Roots are 1,3,0.5,i,-i.

A blue billiard ball with mass m crashes into a red billiard ball with the same mass that is at rest. The collision results in t
sammy [17]
Draw a diagram to illustrate the problem as shown below.
Each ball has mass = m.
The initial velocity of the blue ball = u.
The initial velocity of the red ball = 0.

Initial total momentum is
P1 = m*u + m*0 = mu
Final momentum is
P2 = mv + 3mv = 4mv

Because momentum is conserved,
mu = 4mv
u = 4v

Answer:
The velocity of the blue ball before the collision is 4v.

At a hot dog stand , they serve regular and footlong hot dog at a ratio of 3 to 2 . How many footlongs will be served if there i
garik1379 [7]

Answer:

32 Foot long hot dogs

Step-by-step explanation:

A hot dog stand serves 3 regular hot dogs for every 2 foot long hot dogs. This means they sell 3+2 = 5 together.

If they sell 80 in one day, then you find how many of each by solving the equation 5x = 80.

5x = 80

x = 16.

So 3*16 is the number of regular which is 48.

So 2*16 is the number of foot long which is 32.
