How do you draw a parabola on an equilateral triangle?

To graph a parabola you must find the axis of symmetry, determine the focal distance and write the focal as a point, and find the directrix. These are all the main points you need to be able to draw a parabola.


Find the equation of chord of contact tangent to the parabola?

y=1/2(p+q)x-apq or x1x=2a(y+y1)


If the primary mirror of a telescope have a focal length of 225 centimeters and the eyepiece has a focal length of 7.5 millimeters then what is the magnifying power of the telescope?

The magnifying power of a telescope is the focal length of the scope in millimeters, divided by the focal length of the eyepiece in millimeters. Focal length of scope: 225cm=2250mm Focal length of eyepiece: 7.5mm 2250/7.5= 300X


What is the power of the eyepiece?

The magnification, or power, at which a telescope is operating is a function of the focal length of the telescope's main (objective) lens (or primary mirror) and the focal length of the eyepiece employed.


What is the focal behavior of a study?

The focal behavior of a study is the main behavior or phenomenon that is being investigated or measured in the research. It is the primary variable of interest that the study aims to understand, describe, or explain.


What is X2 xplus3?

Show How to calculate the magnification of a telescope with a 1000mm focal length an8-inch primary mirror a 4-foot body tube and a 25 mm eyepiece?

To calculate the magnification of a telescope, you would divide the focal length of the telescope by the focal length of the eyepiece. In this case, focal length of telescope = 1000mm and focal length of eyepiece = 25mm. So, magnification = 1000mm / 25mm = 40x.


Is a parabola the same as a parabolic curve?

No. If you tilt a parabola, you will still have a parabolic curve but it will no longer be a parabola.


Parabola is the point at which the parabola is at its lowest or highest point?

A parabola is NOT a point, it is the whole curve.
