<span>6x=480 ft
x=80 ft.
Area = x^2 = 80^2 = 6400 sq. ft.</span>
2 x 10 to the 3rd power is
2x10^3
One answer is 6/10 ths; i hope this helps (;
Answer:
y = 2x -2
Step-by-step explanation:
When you shift down or up, you move down or up the y-axis. Here, the 6 was the y-intercept, so you subtract 8 from 6.
Well, "<span>the set of all points in the plane equidistant from the focus and a line", is referring to the focus point of the parabola and the directrix line.
bearing in mind that, both fellows are at a distance "p" from the vertex, that puts the vertex right in the middle of them.
notice, the focus point is below the directrix, meaning, is a vertical parabola, and is also opening downwards, like in the picture below.
from -5 to 5 over the y-axis, there are 10 units, so the "p" distance is 5, so that puts the vertex right at the origin.
since the parabola is opening downwards, "p" is negative, thus -5.
