Remember that for a function of the form 
, a parabola, the focus will be: 
.
We know that the vertex of the parabola is (0,0), and the sun is the focus of the parabola; we also know that the focus is in the positive y-axis and when the comet is as its vertex, the distance between them is 60'000.000 km; therefore the focus of our parabola is (0, 60'000.000).
Now that we know the focus, we can find
using the focus of the parabola:
Now, the only thing left is replacing the value of in our equation :
We can conclude that the equation that represents the path of the comet is

Answer:
The 99% confidence interval is
Step-by-step explanation:
From the question we are told that
The data is 3, 2,5, 3, 2, 6, 5,4.5, 3, 3, and 4
The sample size is n = 11
Generally the sample mean is mathematically represented as
=>
=>
Generally the sample standard deviation is mathematically represented as
=>
=>
Given that the confidence interval is 99% then the level of significance is mathematically represented as
=>
Given that the sample size is small we will making use of t distribution table
Generally from the t distribution table the critical value of at a degree of freedom of is
Generally the margin of error is mathematically represented as
Generally 99% confidence interval is mathematically represented as
=>
