The exponential models describe the population of the indicated country. A, in millions, t years after 2006. Which country has the greates growth rate? By what percentage is the population of that country increasing each year?

Country1:$A=129.3{e}^{0.001t}$

Country 2:$A=1096.9{e}^{0.011t}$

Country 3:$A=28.7{e}^{0.028t}$

Country 3:$A=147.9{e}^{-0.004t}$

We can solve it using exponential growth rate formula as below.

We have the exponential growth rate formula as

Final amount A=(principal value P)$\times {e}^{\text{(rate of interes)(tome)}}$

so from the given data we can extract the rate of interest of country A=0.001

country B=0.011

country C=0.028

country D=-0.004

Here we can see the highest growth rate is 0.028, so its the 1st answer

again the percentage growth rate for this country would be$\frac{0.028}{100}=2.8\mathrm{\%}$ per year

The population of California was 29.76 million in 1990 and 33.87 million in 2000. Assume that the population grows exponentially.

(a) Find a function that models the population t years after 1990.

(b) Find the time required for the population to double.

(c) Use the function from part (a) to predict the population of California in the year 2010. Look up California’s actual population in 2010, and compare.

What rule is used for this simplification?

$\frac{8}{(s+1{)}^{2}+{2}^{2}}\times \frac{1}{s}=\frac{8}{5}-\frac{1}{s}+\frac{16}{10}\times \frac{s+1}{(s+1{)}^{2}+{2}^{2}}+\frac{8}{10}\times \frac{2}{(s+1{)}^{2}+{2}^{2}}$

Obtain the set of real numbers $c$

Show that there exists a positive real number $x\ne 2$ such that ${\mathrm{log}}_{2}x=\frac{x}{2}$ . Hence obtain the set of real numbers $c$ such that $\frac{{\mathrm{log}}_{2}x}{x}$$=c$ has only one real solution.
