<u>Answer:</u>
The correct answer option is (5, -6).
<u>Step-by-step explanation:</u>
We know that the following are the coordinates of a point:
If this point is reflected through y axis, we are to find the coordinates of its image?
If a point is reflected through y-axis, the sign of the x coordinate is changed so we get:
(5, -6)
a)
Check the picture below.
b)
volume wise, we know the smaller pyramid is 1/8 th of the whole pyramid, so the volume of the whole pyramid must be 8/8 th.
Now, if we take off 1/8 th of the volume of whole pyramid, what the whole pyramid is left with is 7/8 th of its total volume, and that 7/8 th is the truncated part, because the 1/8 we chopped off from it, is the volume of the tiny pyramid atop.
Now, what's the ratio of the tiny pyramid to the truncated bottom?
