Answer:
2
Step-by-step explanation:
Take any 2 points on the graph,
(80, 90) & (40, 10)
Use the slope formula:
= (10-90)/(40-80)
= (-80)/(-40)
= 2
Hence, the slope is 2.

Answer:
8923 years
Step-by-step explanation:
Half life of C-14 = 5730yrs
decay rate= 34%
Halt life (t^1/2) = (ln2) / k
5730 = (ln2) /k
k = (ln2) / 5730
k = 1.209 * 10^-4
For first order reaction in radioactivity,
ln(initial amount) = -kt
ln(34/100) = -(1.209*10^-4)t
-1.0788 = -(1.209*10^-4)t
t = -1.7088/ -1.209*10^-4
t = 8923 years
(-2.-1). You can just plug in the numbers. -1=-6+5 is -1=-1. -1-2(-2)=3 is -1--4=3 is 3=3.
