What is a no solution factoring or equations?
If you have a quadratic equation and there is no x to put into the equation to get zero. The graph is like a U that is above the x axis or a cap that is below the x axis.
The equation for the axis of symmetry is?
Your equation must be in y=ax^2+bx+c form Then the equation is x= -b/2a That is how you find the axis of symmetry
What equation is graphed as a vertical line?
Vertical lines only intersect the x-axis. This means that the equation of a vertical line is x=n. The variable n is the coordinate where on the x-axis the line goes.
Where does the parabola cross the x axis?
Set y = 0 and solve for x, with a parabola you should get one, two, or no x-axis crossings, it depends on the equation and the location on the x-y axis of the parabola.
Can you write the equation of a parabola that doesn't cross the x-axis in factored form?
No.
What is the vector equation for the x axis?
ki where i is the unit horizontal vector, and k is any number.
What equation finds the direction of the displacement vector?
In 2 dimensions the angle made by the displacement vector with the positive x-axis is arctan(y/x).
What is the angle measured counterclockwise from the x-axis to vector A?
The angle measured counterclockwise from the x-axis to vector A is the direction of the vector relative to the x-axis. It is typically expressed in degrees or radians, with 0 degrees corresponding to the positive x-axis.
When should you express a vector along the x-axis as a negative vector?
You should express a vector along the x-axis as negative when it points in the negative x-direction relative to a chosen positive direction. This convention helps maintain consistency with vector addition and trigonometric methods.
Can a vector directed along x-axis have y-axis component?
At what angle should a vector be directed to so that its x component is equal to its y component
Can a vector directed along y-axis have an x component?
No, a vector directed along the y-axis does not have an x component. A vector along the y-axis only has a component in the y direction.
Is torque independent of location of axis?
No, the axis must be specified: torque = (distance from the axis) X (force). (X is the vector cross-product in this case - meaning the angle also matters.)No, the axis must be specified: torque = (distance from the axis) X (force).

Is the Cartesian coordinates a scalar or a vector or neither?
A vector is a magnitude with a direction, so if you have a line that is +2 on the x-axis and +2 on the y-axis, that would be a vector.
When should you express a vector along the x axis as a negative vector?
When the arrow representing the vector would point toward negative x.
Vector of negative x axis?
Sometimes denoted by -i.
What is the letter j in maths?
J can be anything u want it to be...but typically j is a vector along y axis ( for example a point has vector equation i+3j+4k this mean that the point is 1 unit along x -axis (i) , 3 units along y-axis (j) , and 4 units along z-axis (k). )
Can a single vector be replaced by two vectors in the x and y directions.?
Yes, a single vector can be represented by two vectors in the x and y directions using vector decomposition. This is known as resolving a vector into its components and can be done using trigonometry. The x-component corresponds to the projection of the vector onto the x-axis, and the y-component corresponds to the projection of the vector onto the y-axis.
