The line of reflection will (always, sometimes, never) be the perpendicular bisector between a preimage and it’s reflected image

frez [133]

Answer:

Step-by-step explanation:

line of reflection: a fixed line directly in the middle of the pre-image and the reflected image.

perpendicular: two lines meeting at a 90 degree angle

bisector: line that divides something into two equal parts

pre-image: the original figure before any transformation or translation has been made

reflected image: the original image after being reflected across the line of reflection.

Is the line of reflection a line running perpendicular, directly in the middle of the pre-image and the reflected image? Yes, always would be my answer.

A shadow 12 meters long is cast by a fir tree that is 16 meters tall. What is the length of the shadow cast by a nearby ash tree

mrs_skeptik [129]

Answer: 5 m

Step-by-step explanation:

Given

Length of 16 m fir tree is 12 m

length of the ash tree is 8 m

Suppose x is the length of the ash tree

angle $c$ made by fir and ash tree will be same as shown in figure

$\Rightarrow \tan c=\dfrac{16}{12}=\dfrac{8}{x}\\\\\Rightarrow x=8\times \dfrac{12}{16}\\\\\Rightarrow x=5\ m$

I need help with this

Reil [10]

Answer:

see attached

Step-by-step explanation:

The domain is the horizontal extent of the graph. The graph extends to infinity in both directions horizontally (that's what the arrows mean). There are no "holes" because the open circle at x=-1 is matched by a filled circle at the same location.

The range is the vertical extent of the graph. The minimum is -3, which is included in the range. The maximum is infinity (as indicated by the up-pointing arrow).
