The scale factor (k)
Since point C is the center of dilation, the scale factor (k) is calculated using:

Answer:
504 in
Step-by-step explanation:
8 × 12 × 6 = 576
Then find the volume of the part that is taken out.
2 × 6 × 6 = 72
and now subtract them
576 - 72 = 504
so your answer is 504in
Answer:
7, 4, 3
Step-by-step explanation:
Using Descartes' rule of signs, you can determine there are zero negative real roots. The above answer choice is the only one with no negative zeros listed.
_____
The count of negative real roots is based on the number of sign changes when the signs of odd-degree terms are reversed. Doing that gives the signs of the terms as - - - -, so there are no changes. That means there are no negative real roots.
A graphing calculator confirms this choice.
First we need to look at the greatest and least points on each axis.
For x - the greatest is 2 and the least is -2 (that is the value of x for the points marked in the top left and right quadrants of the xy axis.
(Note that the points on the number line have a value for x of 1 & -1, but you need to look at highest value of points in all quadrants.)
For y - the greatest would be 3 and the least 0. Looking up and down the Y axis, you can see these intersections for the points given.
Now you need to find the D & R that is suitable for these values. We can only consider the first and last option because it correctly shows that the values for x & 7 must be between 2 & -2 and 0 and 3, The first one is incorrect because they have the D & R reversed. It is x that must be between 2 & -2 and y that must be between 0 & 3.
I hope you found this helpful.
