Determine the image of the point (-5, 2) under a rotation of 90° about the origin.
(-2,-5)
12,5)
(2,-5)
(2,5)

  (2, 5)

Step-by-step explanation:

Rotation clockwise 90° can be accomplished by the transformation ...

  (x, y) ⇒ (y, -x)

so

  (-5, 2) ⇒ (2, 5)

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
