Answer with explanation:
Decay Formula is given by:
R=Rate at which radioactive isotope is decaying.
t=Time Constant
Now, Coming to the Question ,
The Rate at which radioactive isotope is decaying is given by the formula:
⇒346= Initial Amount of Radioactive Isotope
Answer:
uahabsihsb
Step-by-step explanation:
x^2 + 10x + 25
(B/2) ^2
10/2 = 5
5^2 = 25
w in (-oo:+oo)
w/7+13 = -18 // + 18
w/7+13+18 = 0
1/7*w+31 = 0 // - 31
1/7*w = -31 // : 1/7
w = -31/1/7
w = -217
