The dilation transformation gives an image that is similar to the pre-image

but have a different size.

  • Please find attached the required graph of the image created with MS Excel

Reasons:

Points on the figure are; A(-7, -3), B(-3, -2), C(-4, -5)

The scale factor of dilation = 3

The center of dilation = (-7, -6)

Required:

The graph of the image following the dilation.

Solution:

The given points relative to the center of dilation are;

(-7 - (-7), -3 - (-6)) = (0, 3)

(-3 - (-7), -2 - (-6)) = (4, 4)

(-4 - (-7), -5 - (-6)) = (3, 1)

Following the dilation gives;

3 × (0, 3) = (0, 9)

3 × (4, 4) = (12, 12)

3 × (3, 1) = (9, 3)

Adding the coordinates of the center of dilation to the above relative points of the image gives;

Location of point A' = (0 + (-7) , 9 + (-6)) = (-7, 3)

Location of point B' = (12 + (-7) , 12 + (-6)) = (5, 6)

Location of point C' = (9 + (-7) , 3 + (-6)) = (2, -3)

Therefore, the image is; A'(-7, 3), B'(5, 6), C'(2, -3)

Classify each label into the correct category of human red blood cell.
Mazyrski [523]

Classifying each label into the correct category of human red blood cell

A) Human red blood cell shrinks    

  • Cells placed in hypertonic solution
  • More water moves out of cell

B) Normal Human red blood cell

  • Cell placed in isotonic solution
  • Water enters and leaves at the same rate

C) Human red blood cell swells

  • Cell placed in hypotonic solution
  • More water moves into cell

<h3>Types of solution</h3>

A hypertonic solution is a solution with a higher concentration to its surroundings ( i.e contains more solutes like electrolytes than its surroundings ). when a cell is placed in such solution is shrinks gradually and dies off through a process known as plasmolysis. while a hypotonic solution is a direct opposite of a hypertonic solution. Also An isotonic solution is a solution with the same concentration with its surrounding solution.

Hence we can conclude that the classification of each label into the appropriate category are as listed above.
