Researchers are monitoring two different radioactive substances. they have 300 grams of substance a which decays at a rate of 0.15%. they have 500 grams of substance b which decays at a rate of 0.37%. they are trying to determine how many years it will be before the substances have an equal mass.

if m represents the mass of the substance and t represents the elapsed time in years, then which of the following systems of equations can be used to determine how long it will be before the substances have an equal mass?
a.

b.

c.

d.

hi there! my name is zalgo and i am here to you out today. the answer is pretty simple (in a way). this equation equals to 25.2!

i hope this answer !

"stay and stay proud! " - zalgo

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

the answer for the question that you are asking is 4
