Step-by-step explanation:

2) 5.625 mg will be left
Explanation:
1) Half-life = 17.5 days
initial amount of Arsenic-74 = 90 mg
To get the equation, we will use the equation of half-life:


2) we need to find the remaining amount of Arsenic-74 after 70 days
t = 70

So after 70 days, 5.625 mg will be left
Slope=-4 or -4/1
Work:
(2, 5) (3, 1)
x1 y1. x2 y2
M= y2-y1/x2-x1
M= 1-5/3-2
M= -4/1
M=-4
Answer: It would be (0,-2)

Answer:
5.9 years
Step-by-step explanation:
We believe a better representation of the compound interest formula is ...

We want to find the value of t for P=1 and V(t)=2. We are told n=4, so the formula becomes ...
