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:
The measure of arc GE is
Step-by-step explanation:
we know that
The measurement of the external angle is the semi-difference of the arcs which comprises
In this problem
m<A is a external angle
so
substitute the values and solve for the measure of arc GE
An appropriate unit for Abedabun's purpose would have to include $ for the car's maintenance COST and a large distance measurement because we are talking about cars (and they can travel a long distance).
The best answer would be:
C) $/km
$ for the cost and km for the distance the car is driven.
