Kelsey is on a road trip, and is reading a map that has a scale of
1 answer:
Answer:
Her actual distance for the trip will be 112.5 miles.
Step-by-step explanation:
You need to analize the information provided in the exercise.
You know that the scale of the map Kelsey is reading is:
And according to the exercise, Kelsey's trip measures 4.5 inches on that map.
Therefore, in order to calculate what will be her actual distance for the trip (Let be this distance), you can set up the following proportion:
Finally, you must solve for . Then, you get:
Therefore, her actual distance for the trip will be 112.5 miles

Check the picture below.
now, we know the directrix is at y = 1, and the focus point is at 1,3, well, notice the picture, the distance between those fellows is just 2 units.
the vertex is half-way between those fellows, therefore, the vertex will be at 1,2.
the distance "p", from the vertex to either the directrix or focus, is really just 1 unit. Since the focus point is above the directrix, is a vertical parabola, and it opens upwards, like in the picture, and since it opens up, the "p" value is positive, or +1.

Answer:
Vertical compression
Step-by-step explanation:
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
