14 is the asnwer because sqaure root of 200 is 14.14213562 and if you round that it is 14
A half life means that half the sample decays.
If the sample size is 1 , then after one half life there would be x * 1/2 = 1/2 of the sample left.
For the 2nd half life, multiply 1/2 by 1/2 to get 1/4.
So after 2 half lives, there is 1/4 of the sample left, which means 3/4 of the sample decayed.
The answer is 3/4
Answer:
A) 2x + y = -5

E) 2d = 4 - y
Step-by-step explanation:
It Is Going To Be 5 Because 15÷3=5 And 15÷5=3 And 5×3=15 3×5=15
Answer:
(x+1)(x-1)
Step-by-step explanation:
The solutions 1 and - 1 is given when
x = 1 or x = - 1
hence; (x - 1) = 0 or (x + 1) = 0
(x - 1)(x + 1) = 0
x² -1 = 0
Mark as brainliest answer please. Thanks
