Determine whether the statement is true or false. If it is true, explain why. If it is false, explain why or give an example tha

frosja888 [35]

Answer:

False

Step-by-step explanation:

the <u>dot product</u> between two vectors A and B is:

A·B=AB $cos\theta$

where $\theta$ is the angle between the vectors, if they are parallel, this angle is zero. so $\theta=0$

and so the dot product is:

A·B =AB $cos(0)$

and since $cos (0)=1$

the dot product is equal to

A·B=AB

The dot product of parallel vectors is NOT zero

Select the statement that is true about squares from the choices below.

Leya [2.2K]

The answer is (C). All sides and angles of the square is equal. Its diagonals bisect each other and meet at 90°. If two lines are said to meet at 90°, these lines are perpendicular to each other. Therefore, the diagonals of a square is perpendicular to each other

Polygon ABCD is dilated, rotated, and translated to form polygon A′B′C′D′. The endpoints of AB are at (0, -7) and (8, 8), and th

Anton [14]

Rotation and translation are rigid transformations, they don't change figure sizes. Dilation change figure sizes increasing or decreasing them by scale factor.

First, find AB and A'B' by the formula:

$AB=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}= \sqrt{(8-0)^2+(8-(-7))^2}=\sqrt{8^2+15^2}=\sqrt{64+225}=\sqrt{289}=17,\\ \\A'B'=\sqrt{(x_{B'}-x_{A'})^2+(y_{B'}-y_{A'})^2}= \sqrt{(2-6)^2+(1.5-(-6))^2}=\sqrt{4^2+7.5^2}=\sqrt{16+56.25}=\sqrt{72.25}=8.5.$

As you can see AB=2A'B'. This means that the segment AB was decreased twice to form segment A'B'. Then the scale factor is 1/2.
