Give the axis of symmetry of the parabola given by the equation y = 6(x+1)(x-5)? What is eccentricity? What are vertically opposite angles? How many lines of symmetry does a smiley face have? What is a Cartesian equation? Why do parallelograms have only two orders in rotational symmet...
that divides this parabolic curve into two equal halves is known as the six of symmetry of a quadratic function. The axis of symmetry always passes through the vertex and focus of the parabolic curve. So the {eq}x {/eq}-coordinate of the vertex is the equation of the axis of...
Plot another point on thecoordinate planesuch that its y-coordinate is the same as the previous point plotted. For example, (–5, 2). Join the two points plotted using a ruler to get a horizontal line. Uses of Horizontal Lines Horizontal lines are used insymmetryand photography. ...
Find the equation of the line passing through the point (a,b) with slope equal to zero. How do you draw a line of best fit through a set of points on a scatter graph? What is an axis of symmetry? What is the equation of a line that is parallel to y = -4x + 2 and goes thr...
The Vertex formula of a parabola is used to find the coordinates of the point where the parabola crosses its axis of symmetry. The vertex is the point (h,k). As we know the standard equation of a parabola is y = ax2+bx+c. If the coefficient x2is positive then the vertex is the...
When a quadratic is written in vertex form: f(x) = a(x-h)^2 + k Then x = h is axis of symmetry. Another example: g(x) = 2(x+6)^2 + 13 axis of symmetry is x = -6 Upvote•0Downvote Add comment Report Mark M.answered • 12/06/16 ...
Undoubtedly the most famous equation ever written is E=mc². This equation says that energy is equal to the rest mass of the object times the speed of light squared (c is universally accepted as the speed of light). What is this equation actually telling us? Mathematically, since the spe...
To dig deeper into particle dualism, in the second part, a class of models is proposed as a working framework. It encompasses some chaotic excitable reaction-diffusion systems, whose generalized susceptibilities make them compatible with quantized fields and excitations, of any desired symmetry group ...
