Answer:
B is the correct answer
Step-by-step explanation:
A. is wrong because 3/8 would shrink the circle, not expand it.
B. is correct because 8/3 means the circle will expand, not shrink.
C. is wrong because those coordinates only reposition and move the circle, not dilate.
D. is wrong because those coordinates only reposition and move the circle, not dilate.

t = 14/(2 + v)
going upstream -
t = 7/(2 - v)
14/(2 + v) = 7/(2 - v)
(2 + v)/2 = 2 - v

Answer:
VT = 50√3 , PT = 50
Step-by-step explanation:
Given
PV = 100
With reference angle 60°
hypotenuse (h) = 100
perpendicular (p) = ?
Now
Sin 60° = p/h
√3 / 2 = p / 100
p = √3 * 100 / 2
p = 50√3
Also
With reference angle 30°
hypotenuse (h) = 100
perpendicular (p) = ?
sin 30° = p/h
1/2 = p / 100
p = 100 / 2
p = 50
Hope it will help :)
