Atown has a population of 8000 in groves at 4.5% every year to the nearest year how long will it be until the population will reach 22,500

It takes 10 years approximately for the population to reach 22,500

Step-by-step explanation:

Given:

Initial population  =  8000

Population growth rate  4.5 %

Future population = 22500

To Find:

Time taken to reach a population of  22500

Solution:

The population growth can be identified by using

where

N is  future popluation

is the initial population

t is the time taken

r is the rate of the growth

Here we have to find the time t, rephrasing the formula

Substituting the values we get,

t = 9.97

t=10(approx)

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
