Answer:
-3x
Step-by-step explanation:
Fine the average rate of change by the difference in N over the difference in T:
3000 - 500 / 4-0 = 2500 / 4 = 625
This means for every 1 T, N = 625.
Now multiply 625 by 8:
625 x 8 = 5000
When T = 8 N = 5,000
The decay rate can be found by dividing -ln(2) by the half life.
Decay rate = -ln(2) / 5715 = -0.00012
Answer: 1) 2, 3, 4, 9, 32, 279, 8896, 2481705, 22077238784
2) 2,490,924
3) Neither
<u>Step-by-step explanation:</u>


Neither
Not arithmetic because the difference between each of the terms is not the same.
S₂ - S₁ S₃ - S₂ S₄ - S₃
3 - 2 = 1 4 - 3 = 1 9 - 4 = 5
Not geometric because the ratios between each of the terms is not the same.

20-3 x 2 = 14 (using extra space because it needs to be 20 characters long)
3(5b+1)(5b-1)
