here is how to do it:
Explanation:
(h,k) are the coordinates of the vertex. They correspond to (x,y). So, first, you need to plug the vertex coordinates in for h and k in the given formula. Then, to find the a value (slope) you need to plug in the “contains” value in for x and y accordingly. Finally, just solve for a by simplifying algebraically. Make sure to distribute the - sign to your h and k values.
When you have the a value, to write the equation, do the following:
1. make sure to leave the vertex coordinates in the given formula equation
2. take out the “contains” values for x and y.
3. leave in the a value you found
Your completed equation should have the same format as the given formula. However, it should have numbers for the h, k, and a values. The x and y values should stay x and y.
That would be Apogee which is the farthest point of the moon from the Earth. The opposite would be Perigee and this is also when the moon appears larger.
An estuary is where salt water and fresh water meet. Estuaries are usually found at the edge of the coast, where the ocean water, or salty water, meets river, lake, any fresh water source, water.
A tributary is something completely different. It is a, usually smaller than the main river or lake, river/stream stemming off a bigger river or lake, or flowing into that river or lake.
Answer:
Because sun is a 'Star' and other planets are planets and sun is the source of energy for all of the planets.
