Abc is dilated by a scale factor of 0.5 with the origin as the center of dilation resulting in the image abc. if a equals (2, 2), b equals (4, 3), and c equals (6, 3), what is the length of bc?

Yes she is correct. when you do 1/5 the tbe is their to represent the fraction. so yes, kathy got it

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
