Answer:

The most accurate prediction is 46 days but on edg any number will be correct sense it is just a personal prediction.

Explanation:

To show this I put in 999999 and it was correct (even though for some reason it shows it as blank).

Answer:

it takes 46 days to full the pond

Explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.


y = 3.915(1.106)^x is the regression equation where x is the number of days, y the the amount of water.

My answer:

As we can see in the equation:

  • 3.915 is the initial value
  • 1.106 = represents the increase in population at time x

this pond can hold up to 400 water lilies, it means that:


y = 3.915(1.106)^x = 400

<=>
(400)/(3.915)=(1.106)^x

<=>
102.17=(1.106)^x

We convert to sides to log

<=>
log(102.17)=log(1.106)^x

<=>
x=(log(102.17))/(log(1.106))

<=>
x=(2.009)/(0.0437)

<=> x = 45.79

So it takes 46 days to full the pond
