Step-by-step explanation:
<u>The rule of 90° counterclockwise rotation about the origin:</u>
<u>Apply the rule to the point T:</u>
Answer:
Step-by-step explanation:
Each rotation is 360° or 2π radians. So, 36.7 rotations is ...
36.7×360° = 13,212°
or
36.7×2π = 73.4π radians
9514 1404 393
Answer:
0.28 -0.95i
Step-by-step explanation:
Multiply numerator and denominator by the conjugate of the denominator.

_____
<em>Additional comment</em>
If the original number is A∠β, the ratio is 1∠(2β), the square of the unit vector in the same direction as the original.
The function will be

where y is the balance, and x is the number of month.
The raph will be a line on the xy-plain which starts at the point (0, 360), and end in the point (72, 0).
Hope it helps.
Remember, you can do ANYTHING to an equaiton as long as you do it to BOTH SIDES
we can try to get k by itself bymaking that -17 into 0 since k+0=k
-17+17=0 right so
K-17=-12
add 17 to BOTH SIDES
K+17-17=17-12
K+0=5
K=5
