PLEASE HELP!! The exponential model A=308e^0.026t describes the population, A, of a country in millions, t years after 2003. Use the model to determine when the population of the country will be 655 million.
The population of the country will be 655 million in what year

In 2042 the population of the country will be 655 million.    

Step-by-step explanation:

Given: The exponential model describes the population, A, of a country in millions, t years after 2003.

When population of the country will be 655 million. we have

Taking natural log on both sides

Hence, in 2042 the population of the country will be 655 million.   [2013+29 = 2042]

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
