Answer:
We are told that circle C has center (-4, 6) and a radius of 2.
We are told that circle D has center (6, -2) and a radius of 4.
If we move circle C's center ten units to the right and eight units down, the new center would be at (-4 + 10), (6 - 8) = (6, -2). So step 1 in the informal proof checks out - the centers are the same (which is the definition of concentric) and the shifts are right.
Let's look at our circles. Circle C has a radius of 2 and is inside circle D, whose radius is 4. Between Circle C and Circle D, the radii have a 1:2 ratio, as seen below:
If we dilate circle C by a factor of 2, it means we are expanding it and doubling it. Our circle has that 1:2 ratio, and doubling both sides gives us 2:4. The second step checks out.
Translated objects (or those that you shift) can be congruent, and dilated objects are used with similarity (where you stretch and squeeze). The third step checks out.
Thus, the argument is correct and the last choice is best.

Neil Down is doing some remodeling and needs to cut a triangular piece of wood such that the diagonal is 10 feet long, and the sides of the triangle are in a ratio 3:4. How long should each side be?
Answer:
6 and 8
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
Given this,
(3x)² + (4x)² = 10²
9x² + 16x² = 100
25x² = 100
Divide both sides by 25
x² = 4
x = 2
Substitute this into 3x and 4x.
3x = 3 * 2 = 6
4x = 4 * 2 = 8
Thus, the answer is 6 and 8

Round your answer to the nearest hundredth.
9514 1404 393
Answer:
4.41
Step-by-step explanation:
The sides of interest in this right triangle are the hypotenuse and the side adjacent to the given angle. The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(25°) = 4/AB
Multiplying by AB and dividing by cos(25°), we get ...
AB = 4/cos(25°)
AB ≈ 4.41 . . . . units
the following box plot shows the number of years during which 20 schools have participated in an inter-school swimming meet at least how many schools have participated for 6 years or more?
A: 4
B: 5
C: 10
D: 11
Answer:
4 schools
Step-by-step explanation:
Based on the box plot you have given above, the answer would be 20% of the total schools participated for 6 years or more. This is because the part of the box plot wherein it hits 6 years and above is 20%. Thus, if there are 20 schools, then the 20% of it would be 4. In conclusion, there are 4 schools that participated for 6 years or more.

What is the least common denominator for this equation?
A. 9
B. 36
C. 36c
D. 12c
Answer:
B
Step-by-step explanation:
Though it is not obvious, the c belongs in the numberator, not the denominator.
So C and D are both wrong.
9: 3 * 3
3: 3
4:2 * 2
Lowest common denominator = 2 * 2 * 3 * 3
Lowest common denominator = 36
