(02.05 MC) Which one of these transformations would produce an image that is not congruent
to its pre-image?

1) A translation of (x - 2, y +9)

2) A translation followed by a rotation

3) A rotation of 270 degrees about the origin

4) A dilation followed by a translation

The answer is c. 7 (i think) i’m almost sure though

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
