Answer:
5
Step-by-step explanation:
9.4 ft
The track is the circumference of a circle with radius 1.5 ft
The circumference (C) of a circle is calculated using the formula
C = 2πr ← where r is the radius
C = 2 × π × 1.5 ≈ 9.4 ft
D
The ratio of corresponding sides are equal, that is
=
170 cm is the tallest
A(-4, 5) => A'(-4+2, -5) = A'(-2, -5)
B(-6, -4) => B'(-6+2, -(-4)) = B'(-4, 4)
C(4, -4) => C'(4+2, -(-4)) = C'(6, 4)
Hence the new coordinates are A'(-2, -5), B'(-4, 4) and C'(6, 4).
