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:
They ran a total of 4 miles
Step-by-step explanation:
2 1/3 + 1 2/3 = 4
From the plot, the masses of the five smallest sodium chloride samples are all 1/4 ounce. Therefore, we can calculate for their total mass by multiplying the mass by 5:
total mass = 1/4 ounce * 5
= 5/4 or 1.25 ounces
We can get the same result even if we compute for the total mass by taking the sum of their masses:
total mass = 1/4 + 1/4 + 1/4 + 1/4 + 1/4
= 5/4 oz.
