When the vertex is at the origin and the directrix is at y = -2.5, the the parabola must be facing upwards and have a general formula of y = 4a x^2. In this case, a is equal to 2.5 that is, y = 4*2.5 x^2 equal to y = 10 x^2
Answer: 0.00000220524
Step-by-step explanation:
A chord is any line that touches two ends on a circle. Line segment AC is a chord.
A tangent is a line that only touches one point on the circle. The purple line on top of the circle is a tangent line.
A radius is a line from the center to any point on the circle. The red line is a radius.
A secant is like a chord, except it is a line and keeps going. The cyan (sky blue) line is a secant line.
A point of tangency is the point that the tangent line touches. The yellow point on the purple line is the point of tangency.
A diameter is a straight line that crosses the center and two points on the circle. You can say it’s two radii put together. Line segment BD (green) is a diameter.
Hope this helps!
36y + 9
=36 x 1/6+ 9
= 36/6 + 9
= 6 + 9
= 15
