Answer:
Initial value 
, rate of change: 
Step-by-step explanation:
Step 1
Find the rate of change
we know that
In a linear equation the rate of change is equal to the slope
The formula to calculate the slope between two points is equal to
we have
Substitute the values
----> rate of change
Step 2
Find the initial value
The equation of the line into slope-point form is equal to
Substitute
The initial value is the value of y when the value of x is equal to zero (is the y-intercept)
----> initial value
Answer:
25195
Step-by-step explanation:
Answer:
.
Step-by-step explanation:
The given number is 
.
We need to find a rational number in fraction form that is equivalent to given number.
Let 
...(1)
Multiply both sides by 10.
...(2)
Subtracting (1) from (2), we get
Divide both sides by 9.
Therefore, the required rational number is .
Half life = 1250 years
Start amount = 36
End amount = 15
Time = ?
15 = 36 * (1/2)^(x/1250)
0.417 = (1/2)^(x/1250)
ln(0.417) = x/1250 * ln(1/2)
x = 1577.95 years
