Answer:
15549 yrs old
Step-by-step explanation:
To find the decay constant r we use the formula
t1/2 = 0.693/r
t1/2 is the half-life 5700
5700 = 0.693/r
r = 0.693/5700 = 0.000122 per sec
For the 15% remaining from an initial value of 100%, time t is calculated from
N = Noe^(-rt)
0.15 = 1e^(-0.000122t)
we take natural log of both sides
Ln 0.15 = Ln e^(-0.000122t)
-1.897 = -0.000122t
t = -1.897/-0.000122 = 15549.18 yrs
Approximately 15549 yrs old
Answer:
y is 107° and z is 36°
Step-by-step explanation:
73° and y are supplementary angles so they add up to 180°
In looking at it I would guess it is asking which of the points is on the line? To answer that you would have to take each point an plug it into the equation and see if it is true.
3x - 7 = y
A(9,20)
3(9) - 7 = 20
27 - 7 = 20
20 = 20 True - this point is on the line
B(5,0)
3(5) - 7 = 0
15 - 7 = 0
8 = 0 False - this point is not on the line
C(3,2)
3(3) - 7 = 2
9 - 7 = 2
2 = 2 True - this point is on the line
I hope this helps
