b. Find a function which models the amount of radjum f(t), in mg, remaining
after 1 years.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

if x = 1, then the answer is 3.5
