Answer:

1. (x,y)→(y,-x)

2. (x,y)→(-y,x)

3. (x,y)→(-x,-y)

Step-by-step explanation:

1. Rotation 90° clockwise (or 270° counterclockwise) about the origin changes x into y and y into -x, so it has the rule

(x,y)→(y,-x)

2.  Rotation 90° counterclockwise (or 270° clockwise) about the origin changes x into -y and y into x, so it has the rule

(x,y)→(-y,x)

3.  Rotation 180° clockwise  about the origin changes x into y and y into -x, so it has the rule

(x,y)→(-x,-y)

Here you can apply rotation by 90° clockwise twice, so

(x,y)→(-y,x)→(-x,-y)

Answer:

  A) 40

  B) length = 4.275 km; not quite true. See below for explanation.

Step-by-step explanation:

A) Your calculator can tell you the ratio ...

  (national pennies)/(local pennies) = (8×10⁶)/(2×10⁵)

  = (8/2)×10⁶⁻⁵ = 4×10¹ = 40

The national drive collected 40 times as many pennies as the Valley Stream Central goal.

__

B) Multiplying the number of pennies by the diameter of each will tell the length of the line of pennies. That length can be compared to the 5 km distance to determine if the reporter's statement is true. (It is <em>not</em> true.)

  length of string = (length of penny) × (number of pennies)

  = (19×10⁻⁶ km) × (2.25×10⁵) = 42.75×10⁻¹ km = 4.275 km

The length of the pennies laid side-to-side is less than 5.0 km. The reporter's statement is not true.

_____

All scientific and graphing calculators and many 4-function calculators will let you enter numbers in scientific notation.
