Solve 0=4x^2+12x+9 using the quadratic formula.
MAXImum [283]
The quadratic formula is x =  \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}.  With the values from this equation plugged in, it looks like this:

x = \frac{-12 \pm \sqrt{12^2 - 4(4)(9)} }{2(4)} \\  \\ x = \frac{-12 \pm \sqrt{144 - 144} }{8}  \\  \\ x =  \frac{-12}{8}  \\  \\ x = - \frac{3}{2}

The solution is x = - 3/2

PLS HELP!!!
stira [4]

Answer: Option 4

Step-by-step explanation:

\mathbf{u}=\langle 70 \cos 230^{\circ}, 70 \sin 230^{\circ} \rangle\\\\\mathbf{v}=\langle 60\cos 140^{\circ}, 60 \sin 140^{\circ} \rangle\\\\\mathbf{w}=\langle 80 \cos 30^{\circ}, 80 \sin 30^{\circ} \rangle\\\\\\\therefore \mathbf{u}+\mathbf{v}+\mathbf{w}=\langle 70 \cos 230^{\circ}+60 \cos 140^{\circ}+80 \cos 30^{\circ}, 70 \sin 230^{\circ}+60 \sin 140^{\circ}+80 \sin 30^{\circ} \rangle\\\\ \approx \langle -21.675, 24.944 \rangle

\implies |\mathbf{u}+\mathbf{v}+\mathbf{w}| \approx \sqrt{(-21.675)^2 + (24.944)^2} \approx 33.046

Direction: The vector is in the second quadrant, so the direction is about 180^{\circ}-\arctan \left(\frac{24.944}{-21.675} \right) \approx 131^{\circ}
