<span>-4 * -3 = 12
12 * -3 = -36
</span><span>if you start with A1 = -4, then:
A2 = A1 * -3 = -4 * -3 = 12
A3 = A2 * -3 = 12 * -3 = -36
A4 = A3 * -3 = -36 * 108
A5 = A4 * -3 = 108 * -3 = -324 </span>
Answer:
about 70 years
Step-by-step explanation:
Life expectancy (e) improves by 5.7 years every 10 years, so 5.7/10 = 0.57 years per year. For t years after 2009, it can be modeled by ...
e = 0.57t +80
We want to find when that is 120:
120 = 0.57t +80
40 = 0.57t
40/0.57 = t ≈ 70.2
About 70 years from 2009, humanity may achieve a life expectancy of 120 years.
