Which of thr following transformation is not an isometey

dilation

Step-by-step explanation:

Recall the meaning of isometry

In Geometry, an isometric geometric transformation (or isometry) is a shape-preserving transformation (movement) in the plane or in space.

Hence the  isometric transformations can be  reflection, rotation and translation and sometimes also combination of any two or all three.

But dilation means the sizes are either enlarged or shrunk to get a similar figure

Example is photograph of a man, the man will appear proportionally small in the photo

Hence isometry cannot be for dilation since sides in the image cannot be congruent to that of original.

SO answer is dilation

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
