Solve each equation with the quadratic formula. (Show work please)
Snowcat [4.5K]

Answer:

Let b=x

Such that b^2 =8b-8 will x^2=8x-8

Using the almighty quadratic formula

x1={-b+sqrt (b^2-4ac)}/2a

x2={-b-sqrt (b^2-4ac)}/2a

From the question

a=1

b=8

c=-8

x1={-8+sqrt (8^2-4(-8))}/2

x1=(-8+5.66)/2

x1=-1.17

x2={-8-sqrt (8^2-4(-8))}/2

x2=(-8-5.66)/2

x2=-6.83

:.(x1,x2)=(-1.17,-6.83)

A student wants to determine the coefficients of static friction and kinetic friction between a box and a plank. She places the
Arturiano [62]

Answer:

the coefficients of static friction is 0.577

the coefficients of fkinetic friction is 0.54

Step-by-step explanation:

given information

θ = 30°

S = 2.5 m

t = 4 s

- Static friction

F - F(friction) = 0

W sin θ = μs W cos θ  

μs = sin θ/ cosθ

   = tan θ

   = tan 30°

   = 0.577

- kinetic friction

S = v_{0} t + \frac{1}{2} at^{2}

v_{0} t = 0

S = \frac{1}{2} at^{2}

a = \frac{2S}{T^{2} } = \frac{2 x 2.5}{4^{2} }

  = 0.3 m/s^{2}

F - F(friction) = m a

W sin θ - μ W cos θ  = m a

mg sin θ - μk mg cos θ  = m a

g sin θ - μk g cos θ  = a

μk = g sin θ  - a / g cos θ

    = 9.8 sin 30° - 0.3 / 9.8 cos 30°

    = 0.54

What number should be added to both sides of the equation to complete the square?
tino4ka555 [31]

Answer:

Step-by-step explanation:

Take half of the coefficient of x (in other words, take half of 12).  This results in 6.  Square this result, obtaining 36.

Now x2 + 12x = 11 becomes x^2 + 12x  +  36   = 11  + 36, or

                                              x^2 + 12x  +  36   = 47, or

                                                  (x + 6)^2 = 47
