Is the x coordinate of a point that lies on the x-axis negative?
If it is on the X-axis, the the value of x is zero so it is not negative.
Does the point 2 0 lies on the x axis?
Yes.
When the graph of a quadratic function crosses the x-axis twice the x-coordinate of the vertex lies between the two x-intercepts?
The x co-ordinate of a quadratic lies exactly halfway between the two x-intercepts, assuming they exist. Alternatively, the x co-ordinate can be found using the formula -B/(2A), when the function is in the form, y = Axx + Bx + C.
What is a fixed point that lies on the axis of symmetry of a parabola but not on the parabola?
There would be an infinite number of such points. One way to find them is as follows: Let's take a generic parabola: y = ax2 + bx + c Grab it's derivative with respect to x: dy/dx = 2ax + b Let that equal zero, and solve for x: 0 = 2ax + b 2ax = -b x = -b/2a Now we know the x-coordinate of all points that lie on it's line of symmetry. The only one that we don't want being the one that falls on the curve itself. We can find it's y-coordinate by plugging our x-coordinate into the original parabola y = ax2 + bx + c y = a(-b/2a)2 + b(-b/2a) + c y = a(b2/4a2) - b2/2a + c y = b2/4a - b2/2a + c y = b2/4a - 2b2/4a + c y = -b2/4a + c So there we have it. Given a parabola in the format ax2 + bx + c, all points that lie on it's axis of symmetry have an x-coordinate of -b/2a, and a y-coordinate other than -b2/4a + c
Find tan if an angle in standard position and the point with coordinates negative twelve and positive five lies n the terminal side of the angle?
If you draw this angle in a coordinate system, a right triangle is formed in the second quadrant, with length legs 12 and 5 units. If you label with O the angle that is formed by the terminal side and y-axis, you have tan O = 12/5 and O = tan-1 12/5 = 67.38 degrees Thus, the given angle has a measure of 157.38 degrees (90 + 67.38).
What do you know about the y- coordinate of a point that lies on the x-axis?
If a point lies on the x-axis, then you know that the y-coordinate is zero.
When a point lies on the x-axis what do you know about its y-coordinate when a point lies on the y-axis what do you know about the x-coordinate?
They are zero.They are zero.They are zero.They are zero.
When a point lies on the x - axis what do you know about its y- coordinate?
When a point lies on the y-axis, its x coordinate must be zero.
When a point lies on the x-axis what do you know about it y-coordinatewhen a point lies on the y-axis what do you know about its x-coordinate?
If a point lies on the x-axis then by definition it is located at (x,0) ie the y coordinate is 0.If a point lies on the y-axis then it's located at (0,y) ie the x coordinate is 0.
When a point lies on the y-axis what do you know about its x-coordinate?
Its x coordinate is 0.
When a point lies on an x axis what do you know about its y coordinate?
Its y coordinate will be at zero.
When a point lies on the x-axis what do you know about the y-coordinate?
The y coordinate is 0.
When a point lies on the X-axis what do you know about its y-coordinate?
it is 0
When a point lies on the x-axis what do you know about it's y-coordinate?
y-coordinate is 0
What does it mean when the x coordinate or y coordinate of a point is 0?
When the X - Coordinate is 0: The point lies on Y - Axis. Eg. (0,3) lies on Y - Axis Eg. (0,5) lies on Y - Axis Eg. (0,1) lies on Y - Axis When the Y - Coordinate is 0: The point lies on X - Axis. Eg. (2,0) lies on X - Axis Eg. (3,0) lies on X - Axis Eg. (6,0) lies on X - Axis
When a point lies on the x-axis what do you know about it's y coordinate?
We know that its Y coordinate value is zero.
When a point lies on the x axis what do you know about itsy y coordinate?
In that case, the y-coordinate is zero.
