C = Pi * d where C = circumference, d = diameter, r = radius
C = 2*pi *r
we need to watch the units since they are different
Pool A
C = 2 * pi * r
C = 2 * pi * 12 = 24 * pi in feet
Pool B
C = pi * d
change meters to feet
7.5 m * 3.28 ft/ 1 m = 24.6 ft
C = pi * 24.6 = 24.6* pi in ft
Pool B had a greater circumference
24.6 * pi > 24 pi
X intercpe is when y=0
0=6x^2+10x-4
factor
0=2(3x^2+5x-2)
assume
0=3x^2+5x-2
0=(x+2)(3x-1)
set to zero
x+2=0
x=-2
3x-1=0
x=1/3
x intercepts are -2 and 1/3

Answer:
C, F.
Step-by-step explanation:
All angle measures are preserved in a dilation. And if all angle measures are preserved, it makes the triangles similar by the AA similarity theorem.
