(b) is correct. x represents the bill and 0.15 represents the 15% tip on that bill.
Answer:

Step-by-step explanation:
The point P(1,0) and T
are on the unit circle C and the arc length from P to T is x.
Let us assume that point P - x i.e. the point obtained by moving clock wise direction along the circle from P is T'.
Because of the symmetry of the circle about the coordinate axes, the x-coordinate of point T' will be
and the y-coordinate will be
.
So, coordinates of T' are
.
Here we must notice that point T' is the reflection point of T with respect to X-axis. (Answer)
Initially started 20 feet from the ground .
Went uphill 83 feet.
So: 20 + 83 = 103. The coaster is 103 ft above at this point.
Went down 42 feet
So: 103 - 42 = 61.
Went up 128 feet
So: 61 + 128 = 189
Finally, went down 90 feet
So: 189 - 90 = 99
99 ft above ground.
