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
In a Geometric Sequence each term is found by multiplying the previous term by a constant. This constant is 4. -2*4=-8
-8*4=-32 and so on.
Answer:
B.
Step-by-step explanation:
2,400 = 7,500
First of all, you want to isolate the by dividing each side by 7,500.
After doing this, you will get
= 
.
Putting this in the logarithmic form, you get 
= - x
To get rid of the negative sign, you would simply multiply both dies of the equation by -1. So you would get 
= x.
When you simplify 2400/7500, you get 8/25, so the answer is B.
Hope this helps!
