Q:
The exponential function given by \( \mathrm{H}(\mathrm{t}=80,038.18(1.0484) \), where \( t \) is the number of years after 2012, can be used to project the number of centenarians in a certain
country. Use this function to project the centenarian population in this country in 2016 and in 2043 .
The centenarian population in 2016 is approximately
(Round to the nearest whole number.)
Q:
The number of concurrent users of a social networking site has increased dramatically since 2004. By 2013 , this social networking site could connect concurrently 70
million users online. The function \( \mathrm{P}(\mathrm{t})=2.566(1.476)^{\mathrm{l}} \), where t is the number of years after 2004, models this increase in millions of users. Estimate the number of
users of this site that could be online concurrently in 2005 , in 2009 , and in 2012 . Round to the nearest million users.
The number of users of this site that could be online concurrently in 2005 is approximately
(Round to the nearest whole number.)
Q:
Escribe en forma polar los complejos sig
\( z=(\operatorname{sen}(\alpha+\pi)+i \cos (\pi-\alpha) \)
Q:
The number of concurrent users of a social networking site has increased dramatically since 2000 . By 2009, this social networking site could connect concurrently 70
million users online. The function \( \mathrm{P}(\mathrm{t})=2.462(1.481)^{\mathrm{l}} \), where t is the number of years after 2000 , models this increase in millions of users. Estimate the number of
users of this site that could be online concurrently in 2001 , in 2005 , and in 2008 . Round to the nearest million users.
The number of users of this site that could be online concurrently in 2001 is approximately p(8)=37 million.
(Round to the nearest whole number.)
