We can start by combining like terms, the ones with i, and the ones with one as a factor. Since 3+8 is 11 and 4i+2i is 6i, our answer is C. 11+6i
Answer:
Function= T=K/M
Mass of Sample after 40 yrs = 31.746032 grams
Step-by-step explanation:
As time increases, the mass decreases, hence it's inverse proportion
T ∝ 1/M
Function = T = K/M
Using direct proportion to evaluate mass after 40 yrs
when T= 63yrs, Mass = 0.5M
When T = 40 yrs Mass = X
X = 0.3174603M
Hence mass after 40 years = 0.3174603(100) = 31.746032 grams
Actually there are two avoidable risks here: 1) overeating and 2) smoking.
