Tell whether the transformation is a dilation. Explain.No, scale factor isn't the same.Yes, scale factor is the same. - 3. Multiple ChoiceTell whether each transformation is a dilation. Explain.No, scale factor isn't the same.Yes, scale factor is the same
- 4. Multiple ChoiceDoes the image show a dilation?YesNo
- 5. Multiple ChoiceA triangle has vertices with coordinates (2,0), (3, -1) and (-2,-5). If the triangle is dilated using the rule (x,y)→(3x, 3y), what are the coordinates of the dilated triangle?(5,3), (6,2), (1,-2)(6,0), (9,-3), (-6,-15)(2/3,0), (1,-1/3), (-2/3,-5/3)(-1,-3), (0,-4), (-5,-8)
- 6. Multiple ChoiceWhich of the following rules would produce a dilation?(x, y) → (x-3, y-3)(x, y) → (3x, 3y)(x, y) → (x+3, y + 3)(x, y) → (.5x, y+.5)
- 7. Multiple ChoiceA dilation is which of the following:An enlargementA reductionEither an enlargement or a reductionNeither an enlargement or a reduction
- 8. Multiple ChoiceDoes the image show a Dilation?YesNo
- 9. Multiple ChoiceA dilation can produce a larger figure also called a(n)______reductionenlargementscale factorcenter of dilation
- 10. Multiple ChoiceIf B (-10,-6) is dilated with a scale factor of 1/2 using the origin as the center of dilation, what is the coordinate for B'?(5,3)(20,12)(-20,-12)(-5,-3)
- 11. Multiple ChoiceWhich rule represents the dilation shown?(x,y)→(2.5x, 2.5y)(x,y)→(1.5x, 1.5y)(x,y)→(3.5x, 3.5y)(x,y)→(4x, 4y)
- 12. Multiple ChoiceThe figure after a dilation has occurred is called the _________.pre-imageimagedilationscale factor
- 13. Multiple ChoiceWhich rule represents the dilation?(x,y)→(2x,2y)(x,y)→(3x, 3y)(x,y)→(1/3x, 1/3y)(x,y)→(1/2x, 1/2y)
- 14. Multiple ChoiceThe figure before a dilation has occurred is called the _________.pre-imageimagedilationscale factor
- 15. Multiple ChoiceA scale factor of less than one meansthat the image will be larger than the pre-image.that the image will be the same as the pre-image.that you need to subtract that amount off of each side.that the image will be a reduction of the pre-image.
