We have that
1)<span>Circle W has center (−3, 0) and radius 8
the equation of a circle W is
(x+3)</span>²+(y)²=8²
2)<span>Circle V is a translation of circle W, 2 units down.
the center of circle V--------> (-3,0-2)---------> (-3,-2)
3)</span><span>Circle V is a dilation of circle W with a scale factor of 2.
then the radius circle V is 8*2------> 16 units
</span>the equation of a circle V is
(x+3)²+(y+2)²=16²
therefore
case <span>A. Circle V and circle W are similar.---------> is correct
</span>because I can transform circle V to circle W using only translations, rotations and scaling (In the case of circles, no rotations are necessary).
case <span>B. Circle V and circle W have the same center.-------> is not correct
case </span><span>C. The radius of circle V is 16.-----------> is correct
case </span><span>D. The center of circle V is (−5, 0).----------> is not correct
the answer is
</span> case A. Circle V and circle W are similar.---------> is correct
case C. The radius of circle V is 16.-----------> is correct
We need 2880 person-hours and we have 12 people.
When we divide the work between them: 2880/12 = 240 hours required to complete.
Plug in -2 for a, 3 for b, and -5 for c. Then it'd be | (-3)^2 - 2(-2)(-5) +5 (3) |. Then, multiply everything to get | 9 -20 +15 |. Then, add/subtract to get | 4 |. Finally, take the absolute value and get 4.
