Answer: I think b but don’t take my word
Step-by-step explanation:
About 50 miles. hope this helps!
Part 1: The general form for this matches y^2 = -4cx, which implies that this opens to the left. (Imagine assigning any value of y, whether positive or negative, which would result in a positive left-hand value. Then to match this sign, the value of x must be negative so that the right-hand side becomes positive as well.)
Part 2: The distance from the vertex to the directrix is given by c. This equation has its vertex at the origin (0, 0). If it opens to the left, the directrix is a vertical line to the right of the origin. This equation is y^2 = -4(1/2)x, so c = 1/2, and the directrix has the equation x = 1/2.
Part 3: The focus is inside the parabola, but it is the same distance from the vertex as the directrix. This distance is 1/2 units, and it will be to the left of the vertex. So the focus is at (-1/2, 0).
C i think i hope its right
Answer:

A person should work 32 hours to earn $384
Step-by-step explanation:
A worker's earring E are a function of the number of hour, H at a rate of 12/hr.
We need to write the function.
The function will be:
Earning is represented by E and Hour is represented by H

Now, How many hours would a person have to work to earn 384
We are given E=384, we need to find H
Putting values in above function and finding hours H

So, A person should work 32 hours to earn $384
