Answer:
Step-by-step explanation:
Since the vertex is right between the vertex and the directrix, the y value of the vertex must be (3+(-1))/2=1. The x coordinate will just be the same as that of the focus, or in this case 0. This means that the vertex will be at (0,1). Since the graph opens toward the focus, it will be opening up, and since its vertex is at (0,1), it will have an equation of:

Answer:
Morgan family picked 144 Braeburn apples, 96 Cortland apples, 72 Fuji apples and 48 Rome apples.
Step-by-step explanation:
Let B, C, F and R represent Braeburn apples, Cortland apples, Fuji apples, and Rome apples respectively.
We have been given that Morgan family picked a total of 360 apples. We can represent this information in an equation as:
We are told that Morgan family picked twice as many Braeburn as Fuji. We can represent this information in an equation as:
We are told that Morgan family picked twice as many Cortland as Rome, that is:
We are told that Morgan family picked 50% more Fuji than Rome, that is:
Upon substituting equation (4) in equation (2), we will get:
Now, each apple in in terms of Rome apples, so we will get:
Let us solve for R.
Therefore, Morgan family picked 48 Rome apples.
Upon substituting in (3), we will get:
Therefore, Morgan family picked 96 Cortland apples.
Upon substituting in (4), we will get:
Therefore, Morgan family picked 72 Fuji apples.
Upon substituting in (2), we will get:
Therefore, Morgan family picked 144 Braeburn apples.
