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
The answer is -7 :) hope this helps
Answer:
504
Step-by-step explanation:
So a times 10^n where 1≤|a|<10 and n is an integer is what i learned
so
a.
234=
2.34 times 100=
2.34 times 10²
b.
0.000052=
5.2 times 1/100000=
5.2 times 10⁻⁵
c.
-220000=
-2.2 times 100000=
-2.2 times 10⁵
d. ok, so just count the spaces moved to the left
-18.2 times 10⁻¹⁵
Its d) f(x)= 300+50x/2+x..............................................................................
