Regression equation : y = 3. 915(1. 106)x. Which two equations below could you solve to find D, the number of days it takes the water lily population to double? 2 = 3. 915(1. 106)D 7. 830 = 3. 915(1. 106)D 7. 830 = 3. 915(2)D 2 = 1. 106D.

Respuesta :

The initial number was 3.915 and doubled to 7.830

Regression equation  y = 3. 915(1. 106)x

7.830=3.915(1.106)D

we have to find the value of D.

This is the concept of algebra,

suppose the initial number was x, and the new number is 2x.

The constant rate of growth is r and time is D,

Then,

what is the  function representing growth?

[tex]2x=x(r)D[/tex]

from our choices the equations that represents the information above will be:

7.830=3.915(1.106)D

and

7.830=3.915(2)D

Therefore

from both equations we see the initial number was 3.915 and doubled to 7.830
