Answer:
The period of Y increases by a factor of with respect to the period of X
Step-by-step explanation:
The equation shows the relationship between the orbital period of a planet, T, and the average distance from the planet to the sun, A, in astronomical units, AU. If planet Y is k times the average distance from the sun as planet X, at what factor does the orbital period increase?
For the planet Y:
For planet X:
To know the factor of aumeto we compared with
We know that the distance "a" from planet Y is k times larger than the distance from planet X to the sun. So:
So
Then, the period of Y increases by a factor of with respect to the period of X
Answer:
We conclude that:
- f(2) = -5
Step-by-step explanation:
Given the function
In order to determine the value f(2), we need to check the value of y at x = 2.
In other words, we need to check:
at x = 2, what is the value of y?
From the graph, it is clear that at x = 2, the value of y = -5
In other words,
f(2) = -5
Therefore, we conclude that:
- f(2) = -5
