Solve by quadratic formula. x squared plus x plus 1 = 0
Tasya [4]

Remember that the quadratic formula is: \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}.


a stands for the coefficient of the first term, the one associated with the x^2, b stands for the coefficient of the second term, the one associated with x, and c stands for the value of the constant.


In x^2 + x + 1 = 0, our a-value is 1, our b-value is also 1, and our c-value is also 1.


Thus, when we plug in our values into our formula, we get the answer:

\dfrac{-1 \pm \sqrt{1^2 - 4(1)(1)}}{2(1)} = \dfrac{-1 \pm \sqrt{-3}}{2}


Simplifying this answer using i = \sqrt{-1}, we get our final answer of:

\boxed{x = \dfrac{-1 \pm i\sqrt{3}}{2}}

Help?
Pachacha [2.7K]

Answer:

<em>The correct option is:  32.4 km/h</em>

Step-by-step explanation:

The fastest recorded speed of a turtle while swimming is 9 m/s.

Now,  9 m/s =\frac{(9)meters}{(1)second}

1 kilometer= 1000 meter

So, 1 meter = \frac{1}{1000}=0.001 kilometer

and <u>9 meters</u> =(9*0.001)kilometer = 0.009 kilometer

Now, 1 hour = 3600 seconds

So, <u>1 second</u> =\frac{1}{3600}hour

Thus, we will get.........

\frac{(9)meters}{(1)second}=(\frac{0.009}{\frac{1}{3600}}) kilometer/hour =(0.009*3600)=32.4 km/h

So, the speed of the turtle will be 32.4 km/h.
