What is the equation of a parabola with (−2, 4) as its focus and y = 6 as its directrix?
Well it is concave down with a focal length of 1 and the vertex at (-2,5)
so
\((x-h)^2=4a(y-k)\\ (x+2)^2=4*-1*(y-5)\\ (x+2)^2=-4(y-5)\\\)
\frac{2\sqrt[3]9}{1 + \sqrt[3]3 + \sqrt[3]9}.
\(\frac{2\sqrt[3]9}{1 + \sqrt[3]3 + \sqrt[3]9}\\\)
I do not think this can be simplified.
Technology has been around for ever. When the first cave man chipped at a stone to make a sharp blade, that was technology.
Not quite Yimpy,
You have changed the inequality to an equal sign :)
You should know that the circumference on a circle is 2pi r
well
the angle in a revolution is also 2pi radians and you should know it is also 360 degrees so...
\(360\;\; degrees=2\pi\;\;radians\\ 180\;\; degrees=\pi\;\;radians\\ so\\ \frac{x}{180}*180\;\; degrees=\frac{x}{180} \pi\;\;radians\\ x \;\; degrees=x*\frac{\pi}{180} \;\;radians\\~\\ 330 \;\; degrees=330*\frac{\pi}{180} \;\;radians\\\)
what is the best way to work out 216 hours into seconds??????
Multiply by 60 to turn into minutes,
then multiply by 60 again to turn into seconds
I would also like to see someone answer this question.
I have not seen a question like this before.
Suppose we decide to expand the NCAA basketball tournament to include 512 teams. The following exercise refers to this scenario.
What exercise??
I think that we need more information ://
