Despite control measures, the pigeon population in Winchester is increasing by 10% each year. If there are currently 9,520 pigeo
TEA [102]

Using an exponential function, it is found that there will be 32,866 pigeons in 13 years.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

The initial value and the growth rate are given by:

A(0) = 9520, r = 0.1.

Hence the function is given by:

A(t) = 9520(1.1)^t

Hence in 13 years, the amount of pigeons will be of:

A(13) = 9520(1.1)^{13} = 32866

What would the ewuation be if a line goes through points -7,10 and 1,4
Makovka662 [10]
Do y-y over x-x
So 10-4 = 6 and -7 - 1 = -8
6/-8 = -.75 is your slope
plug it into a y= Mx + b equation along with a y and x pair
4 = -.75(1)+ b
4 = -.75 + b
Solve the equation which gets you to b= 4.75
So y = -.75x+ 4.75 is your answer
