Answer:
a. - 45 feet
b. - 18 feet.
Step-by-step explanation:
If we consider the water level as the reference level then the elevation of the fish is - 27 feet, i.e. the fish is 27 feet below the water level.
a. Now, the fish decreases its elevation by 32 feet and then increases its elevation by 14 feet.
Therefore, the new elevation of the fish is (- 27 - 32 + 14) = - 45 feet.
b. Now, if my elevation is of the new elevation of the fish then my elevation will be =
feet. (Answer)
Answer:
B' = (-4, -4)
Step-by-step explanation:
<u>Dilation</u>: A type of transformation that makes the pre-image larger or smaller without changing its shape.
<u>Center of a dilation</u>: a fixed point about which all points are dilated.
Given:
For dilation when the <u>center of dilation</u> is the origin (0, 0), simply multiply the coordinates of the vertices of the pre-image by the given scale factor to find the image under dilation:
Therefore:
A' = (1 x 4, 2 x 4) = (4, 8)
B' = (-1 x 4, -1 x 4) = (-4, -4)
C' = (0 x 4, -2 x 4) = (0, -8)
Answer: The correct option is A.
Explanation:
From the given figure it is noticed that each box in the graph represents the length of 2 units. The coordinates of point A,B and C are (-1,1),(-3,3) and (-2,4) respectively.
If a point reflects over the y-axis then,
So after reflecting coordinates of point C become,
If a point translated by (a,b), then
So, after reflection over y-axis followed by translation by (2,-2), the coordinate of C are,
Similarly the image of point A and B are (3,-1) and (5,1) respectively.
The image of C after reflection over y-axis followed by translation by (2,-2) is (4,2), which is shown in only graph A, Therefore A is the correct option.
