We are given that x is the arclength from P(1,0) to T(3/4,4/5). In the case of a unit circle, the arclength from P(1,0) to a point T on a unit circle is equal to the radian angle that we rotate from the positive x axis up to T(3/4,4/5). So x is some radian angle. We don't actually have to solve for x, but you can find it using arctan (.8/.75) = 0.8176 radians or about 46°
Then we are told to add π to this x. If you add a rotation of π to a point on a circle, you are rotating that point by 180°. A 180° rotation about the origin is the same as a reflection about the origin. Recall that the transformation for a 180° rotation is (x,y) -> (-x, -y).
Therefore it should be T ' (-3/5, -4/5).

Answer:
4800 words.
Step-by-step explanation:
I assume you want to find the amount of words in 1 hour. That would be 2400 x 2 which is equal to 4800.
