Directly from my math log.
All right I know the problem is long but I have done some of the work. I just need you guys to check if I did it right or not.The table shows how the weight of a chicken embryo inside and egg changes over time.
- A power function has the form
where
and
are constants.
- You can use an exponential function to model a set of data pairs
if there is a linear relationship between
and
.
- You can use a power function to model a set of data pairs
and
- Make a scatter plot, on your own graph paper, of the data pairs
. What relationship exists between
?
- Find an equation giving
as a function of
.
- A chick hatches 21 days after the egg is laid. Estimate the weight of a chick when it hatches.
Some of the questions asked a kind of vague to me so I don't really understand what it's asking. Help of any kind would be appreciated.
- I graphed the data on graph paper and in my calculator based on
- I found the equation by using linear regression on my calculator after I plotted my points of
as the equation. But I also plot the graph based on
and I found the power regression of the data which came out to be
and fit the data almost precisely. So which equation should I put as the answer?
- For this I got 45.476 g, when
based on the equation
BTW - The table is attached to the thread.
