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.
Answer:
Step-by-step explanation:
We are told that the average human heart beats times per day and there are days in one year.
To find number of heart beats in one year we will multiply number of heart beats in one day by number of days in one year.
Now we will solve this problem using exponent properties.
Our answer is in scientific notation we can represent it in standard form as times.
Therefore, average human heart beats in one year or 41975000 times.
