Math problem growth rate By the way, I feel dizzy. The question is like this In order to meet the needs of urban development, it is planned to make the urban green space area reach 71.3 hectares by the end of 2007. Try to find the growth rate of the green space area at the end of 2007 compared with that at the end of 2005 (the green space area was 62 hectares in 2005). I remember that I learned the growth rate, but I forgot to help

The growth rate is (71.3-62) / 62 = 16.6%



Mathematical problems on growth rate
The per capita income of a village is 1200 yuan in 2001 and 1450 yuan in 2003. To find the average annual growth rate of per capita income, a quadratic equation with one yuan is needed


Suppose the annual average growth rate is p
In 2001, the per capita income was 1200 yuan
In 2002, the per capita income was 1200 (1 + P) yuan
In 2003, the per capita income was 1200 (1 + P) ^ 2 yuan
So you can get it
1200(1+p)^2=1450
Just solve it



About annual growth rate
In order to develop education, a county has strengthened its investment in education funds. In 2009, it invested 30 million yuan, and is expected to invest 50 million yuan in 2011


If the average annual growth rate is known to be x, then the input in the t-th year is f (T) = a (1 + x) ^ t, where a is the initial input and ^ t is the power of T



Math problem, about growth rate
Guangdong's GDP was 25968.55 in 2006 and 5733.97 in 1995. What is the growth rate?
The answer is 25968.55 divided by 5733.97-1 = 352%
Excuse me, why the last one? If it's because of the year, there are 11 years from 1995 to 2006


5733.97 as the principal of bank interest
5733.97*(1+3.52)=
