Therefore, the rock hits the ground between t = 2 seconds and t = 2.5 seconds after it is dropped.
Answer:
The standard form of the equation of the circle is .
Step-by-step explanation:
A circle is the set of points in a plane that lie a fixed distance, called the radius, from any point, called the center.
The equation of a circle in standard form is
where <em>r</em> is the radius of the circle, and <em>h</em>, <em>k</em> are the coordinates of its center.
When the center of the circle coincides with the origin , so
We are also told that the circle contains the point (0, 1), so we will use that information to find the radius <em>r</em>.
Therefore, the standard form of the equation of the circle is .
Hello there! :)
Given:
x-coordinate of point = -2
y-coordinate of point = 5
Slope, or "m" = 1/5
Substitute in these values into slope-intercept formula (y = mx+b)
5 = 1/5(-2) + b
5 = -2/5 + b
25/5 = -2/5 + b
27/5 = b
Rewrite the equation:
y = 1/5x + 27/5
Graph the equation using a graphing utility:
