Four friends participated in a speed-typing contest. Who has the slowest typing speed? A.

Georgie: 320 words in 8 minutes
B.

Tara: 403 words in 10 minutes
C.

Frank: 474 words in 12 minutes
D.

Lupe: 567 words in 14 minutes

Let's find the unit rate for each contestant, OK ?

Georgie: 320 words in 8 minutes.

320/8 = 40.0 words per minute

Tara: 403 words in 10 minutes

403/10 = 40.3 words per minute

Frank: 474 words in 12 minutes

474/12 = 39.5 words per minute

Lupe: 567 words in 14 minutes

567/14 = 40.5 words per minute

Frank is slowest, at 39.5 wpm.

Georgie is next, at 40.0 wpm.

Tara is next, at 40.3 wpm.

Lupe is fastest, at 40.5 wpm, just barely beating out Tara.

correct answer:

i^31 = -i

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
