?

I hope some of you may be able to answer, but I was wondering how much time ON-SITE early earthquake warning systems would give ahead of time before impact if the city was above the active seismic fault?

Is there a shortcut (preferrably mental) to solve these kinds of problems? Thank you

When:

n! = (3!)(5!)(7!)

I ve gone so far as to

n!/7! = 5 x 9 x 16

but got stuck there, have verified the above to hold true.

please help, Thank you

What is the area of a circumscribed circle of a triangle whose sides are of length 6,8 and 10?

Please explain. Thank you

If the volume occupied by a gas is mostly empty space, then why is that space still being considered as space occupied by the gas?

I already have one about the relationship between respiration time and volume of air in lungs and also one about rollercoaster height. I hope you guys might know some (preferrably > 3 degree). Greatly appreciate it!

I remembered seeing it once, maybe from a book. I tried looking for it on the internet but to no avail, maybe my search terms weren't sufficient I don't know. So I was hoping that maybe some of you guys know what it is or where I could find it. We need examples of polynomial functions applied in the real world, I hope you can give me some ideas of those as well. I greatly appreciate it! Good day

Can light (photons), in a true, pure vacuum, travel indefinitely??

All I know is that its Filipino title (translated) is Parang Sine, If anyone knows please tell me. I would greatly appreciate it.

I had a go at it and I just want to see if my answer is alright:

In triangle PQR, RP = RQ = 12cm. Let S and T be points on sides RP and RQ respectively, such that RS = RT = 8cm. Let X be the point of intersection of the segments PT and QS. If the area of quadrilateral RSXT is 8 cm^2, what is the area of triangle PQR?

A box contains 2 red, 2 green and 2 blue balls, if 2 balls are picked randomly from the box, what is the probability that they are the same color?

I have studied some french before (but you can't assume that I'm even mediocre at it), It was compulsory back in Singapore but I did not take it seriously, now that I'm not studying there anymore I regret having done so. Thank you

Billy’s father is twice Billy’s age. Eleven years ago, Billy’s father was thrice Billy’s age then. How

old is Billy now?

TL;DR Title

My friend and I got worked up on this and unfortunately no teacher was present during the time to quench our curiosity, searching through the internet proved unfruitful.

Basically he asked me to give him a polynomial equation for an exercise and I gave him a 5th degree with mostly arbitrary coefficients.

By the Bounds of zeros theorem, finding the upper bound requires obtaining all positive coefficients when doing synthetic division, but how do we do that when the first step of synthetic division is bringing down the coefficient of the first number, which is already negative?

Is there like a word or phrase other than ↑ or not? Thank you

I have come up with my own but I'm not sure of it at all

{P(x) | an ... a0 (is an element of) Z}

↓

{x = p/q | p = (factors of a0); q = (factors of an)}

I'm new to this and I hope you guys could help me and explain what it means as well. Thank you very much
