Learn the concept of the axis of symmetry of a geometrical shape. Understand the formula for finding the equations of the axis of symmetry & vertex of a parabola. Related to this Question Give the axis of symmetry of the parabola given by the equation y = 6(x+1)(x-5)?
Axis of Symmetry Formula There are two different formulas that you can use to find the axis of symmetry. One formula works when the parabola's equation is invertex formand the other works when the parabola's equation is instandard form. ...
Substitutinga= 2 andb= 1 into this formula, we have: x=−b2a=−(1)2(2) Note:It useful to put parentheses around the values we are substituting in order to avoid arithmetic mistakes. Step 3:Simplify the equation This gives us the vertical line that is the axis of symmetry of...
I believe x=-b/2a is the axis of symmetry, not y=-b/2a, as you explain. Report 01/10/14 Steve S. One way to remember this is with the Quadratic Formula: x = (-b±√(b^2-4ac))/2/a = -b/2/a ±√(b^2-4ac))/2/a The roots are equal distances from the value x ...
The region bounded by the y-axis, x=y-y^3 is a parabolic shape that opens towards the positive x-axis, with the y-axis as its axis of symmetry. Can the center of mass be outside of the bounded region? No, the center of mass of a thin plate in a bounded regio...
The moment of inertia for continuous rigid bodies is readily calculated for some simple geometric shapes about an axis that coincides with an axis of symmetry of the body. The calculation of I using Equation (7-18) may be more difficult for bodies with less regular shapes. Equation (7-18)...
