What is the halflife
blagie [28]
To model half-life, use the formula A(t)=A_0 (\dfrac{1}{2})^{ \frac{t}{t_{1/2}}. Here, A(t) is the amount remaining after a length of time t. A_0 is the amount that you start with. t_{1/2} is the half-life. You plug in 50 for t_{1/2}, 10 for A_0, and 25 for t. You get A(t)=10( \frac{1}{2})^{25/50} = 10( \frac{1}{2})^{1/2} = 7.07 \ grams.

If a+b+c=0 for a,b,c then prove a²/bc+b²/ca+c²/ab=3.
Ierofanga [76]
According to the identity if a+b+c=0
then a3+b3+c3=3abc
a3+b3+c3/abc=3
a2*a/bc*a+b2*b/ca*b+c2*c/ab*c=3
cancel a,b,c in   all the fraction then you get
<span>a²/bc+b²/ca+c²/ab=3.

Katyanochek1 [597]

Answer:

6.25716517287
