I think answer should be thousands please give me brainlest I hope this helps let me know if it’s correct or not okay thanks
Answer:
Y=0.1(1.25)^t is growth. Y=426(0.98)^t is decay. Y=100(1-1/2)^t is decay. Y=((1-0.03) 1/2) ^2t is decay. And y=2050(1/2)^t is decay. Hope this helps!
Step-by-step explanation:
Im pretty sure it would be B) 100
Option a is not a function because for x = 0, y = 3 and 4.
option b is a function.
option c is not a function because for x = 2, y = 1 and 8.
option d is not a function because for x = 1, y = -3 and 4
so, something fused, and that amount was 20% of the whole thing.
1420 grams did not fuse, and since a whole is 100%, 100% - 20% = 80%, so that has to be the remaining 80%.
since we know that 1420 is 80%, what is 20%?
![\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 1420&80\\ x&20 \end{array}\implies \cfrac{1420}{x}=\cfrac{80}{20}\implies \cfrac{1420}{x}=4\\\\\\ \cfrac{1420}{4}=x\implies 355=x \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \stackrel{\textit{total mass, \textit{na}mely 100\%}}{1420~~+~~355}\implies 1775](https://tex.z-dn.net/?f=%20%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7D%0Aamount%26%5C%25%5C%5C%0A%5Ccline%7B1-2%7D%0A1420%2680%5C%5C%0Ax%2620%0A%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B1420%7D%7Bx%7D%3D%5Ccfrac%7B80%7D%7B20%7D%5Cimplies%20%5Ccfrac%7B1420%7D%7Bx%7D%3D4%5C%5C%5C%5C%5C%5C%20%5Ccfrac%7B1420%7D%7B4%7D%3Dx%5Cimplies%20355%3Dx%0A%5C%5C%5C%5C%5B-0.35em%5D%0A%5Crule%7B34em%7D%7B0.25pt%7D%5C%5C%5C%5C%0A%5Cstackrel%7B%5Ctextit%7Btotal%20mass%2C%20%5Ctextit%7Bna%7Dmely%20100%5C%25%7D%7D%7B1420~~%2B~~355%7D%5Cimplies%201775%20)
