A triangle with a vertex at A(4 -8) is dilated so that A' has coordinates (-3 6). The scale factor used was?
It depends where the centre of enlargement (dilation) was; it can be any value.As all you have given us is the change in the coordinate of the A vertex, so all we can conclude is that the centre of enlargement is somewhere along the line y + 2x = 0.Examples:If the centre is at (3, -6) then the scale factor is -6If the centre is at (0.5, -1) then the scale factor is -1If the centre is at (0, 0) then the scale factor is -3/4If the centre is at (-3, 6) then the scale factor is 0If the centre is at (-4, 8) then the scale factor is 1/8If the centre is at (-10, 20) then the scale factor is 1/2If the centre is at (11, -22) then the scale factor is 2If the centre is at (1.4, -2.8) then the scale factor is 6(As the centre tends towards ±∞ the scale factor tends towards 1 [from below towards -∞, from above towards +∞].)
How can you spread the word about child safety?
On a local scale, you could put an advertisement in the paper that tells the importance for child safety. For an attempt at spreading the word globally, one could try setting up a website or blog.
What is a negative scale factor?
A negative scale factor is used to produce the image on the other side of the centre of enlargement (scaled to the absolute value of the scale factor).
Is there a scale to tell how autistic a child is?
No, there is no scale to tell 'how autistic' a child is. A child is either autistic or they're not, there is no scale of 'how autistic' a person is just as there's no scale for how Chinese someone is or how female someone is.

What is an enlargement with a negative scale factor?
It is a smaller shape on the other side of the centre of enlargement.
Transformation that enlarges or reduces a figure?
Scaling changes the size of a figure. If the scale factor is greater than 1, the figure is enlarged; if the scale factor is less than 1, the figure is reduced. I the scale factor is equal to 1, the figure's size is unchanged. If there is a centre of enlargement, the new figure can be drawn exactly by multiplying the distance of every point from the centre of enlargement, multiplying this by the scale factor and drawing the new point at this distance from the centre of enlargement. (For a polygonal figure, only the vertices need be measured and the lines between the vertices of the original figure drawn in). With a centre of enlargement, the scale factor can be negative. In this case, the distance to the new points is measured on the opposite side of the centre to the original points, so that it is a straight line form the original point, through the centre to the new point.
Enlarge shape A with a scale factor of -½ centre O whats this mean - especially the centre 0?
When enlarging a shape through a centre (O in this case, which is the usual letter of the origin for x/y axes) measure the distance from each point on the shape to the centre of enlargement, multiply it by the scale factor to get the new distance and then (keeping the measuring device, eg ruler, still) measure the new distance from the centre.By having a scale factor the exact size of the image is known; andby having a centre of enlargement the exact position of the image is known.Note: When the scale factor is negative, the distances will change sign and so be measured in the opposite direction.So in this case, the following will happen:. . . . . . . . . . . . . . . . . . . . . .. . . ./\ . . . . . . . . . . . . . . . . .. . . / .\. . . . . . . . . . . . . . . . .. . ./__\ . . . . . .O . . . \ . . ./. .. . / . . .\. . . . . . .* . . . \--/. .. ./. . . . \ . . . . . . . . . . .\/ . . .. / . . . . .\. . . . . . . . . . . . . . .. . . . . . . . . . . . . . . . . . . . . .Where the A shape on the left becomes the (smaller) upside down A on the right when enlarged with a scale factor of -½ and centre O.(You'll have to excuse the ASCII graphics for not complete accuracy.)
A transformation that proportionally reduces or enlarges a figure?
Scaling will proportionally reduce or enlarge a figure. The amount of scaling is given by the scale factor (greater than zero) If the scale factor is less than 1, the figure is reduced and it is sometimes called a contraction If the scale factor is greater than 1, the figure is enlarged, and it is called a dilation or enlargement. If a centre of enlargement is used, the distance of every point from the centre is multiplied by the scale factor. The scale factor can be negative in which case the distance to the new point is measured on the opposite side of the centre to the original point.
What is the meaning of a 'scalability issue'?
When you have a process that works on a small scale or in small batches and there is a question as to whether it can be made to work in larger batches or on a larger scale, that is a "scalability issue." Basically it is when there is a question as to whether it can be scaled up.
