Dear YMG Community,
It is with pleasure to update you with the following developments:
The last couple of months, YMG has been engaged in fulfilling its duty to the first batch of 25 YMG scholars. My dedicated team worked hard to ensure that each scholar gets the award he or she deserves. We did this by contacting each of their schools and paying for their fees. Unfortunately, it did not go smoothly in certain cases, as schools have strict protocols and at times were just uncooperative. Nonetheless, YMG remains committed in helping the community and its scholars achieve the promise of accessible education through the YMG Scholarship Program (YMGSP).
Unbeknownst to everyone, the YMG website just went thru a major housekeeping. Certain key features have been upgraded to better cater the ongoing application for the second and future batches of the YMGSP. With this upgrade, evaluating and selecting the next batch of YMG scholars becomes more efficient. However, due to a recent server upgrade, receiving applications was temporarily put to a halt. At this time, the YMG website is fully functional and is again ready to receive applications.
In order for our aspiring YMG scholars to complete their application, and to give us ample time in evaluating a lot of applications and at the same time assisting our existing YMG scholars, I, together with my Executive Board, decided to push the deadline for the second batch of the YourMathGuru Scholarship Program to November 30, 2015. This gives everyone the sufficient time they need.
Thank you very much for everyone’s continuing support. The YMG family has indeed evolved from being a simple online forum to a growing, socially aware and mathematicsdriven community.
Always in service,
Engr. Alex Argimón

Given x^2+bx+2c=0 What value in terms of c must b have to make this expression a perfect square?

polonium210 is a radioactive element with a halflife of 140 days. This means that half of the polonium decays every 140 days. If 400 mg is the initial sample how much is left after 700 days?

Yeah Member

and what is the formula?

Yeah, Sorry for the delayed response! The basic equation for half life is AT = A0 2^(T/H) where A0 is the initial radioisotope’s activity, AT is the decayed activity after time T, and H is the halflife. These values in your problem would be: A0=400 mg and AT is what they are asking for. AT=400x[2^(700/140)]=400×2^(5)= 400x (1/2^32) = 400/32= 12.5 mg

(x^2y^4)^2=x^4y^8 Always multiply the outer exponent by the exponent of each factor (or by both the exponent of the numerator and the denominator if it is a ratio)!!!!
