On the plane curve defined by the parametric equations below, what point corresponds to t= -1
2 answers:
The equation x=2t-1 represent the x-coordinate. To get the value of x, substitute t with -1.
That is: x = 2(-1) - 1
= -2-1
= -3
Likewise, the equation y=t∧-3 represent the y-coordinate. Substituting t with -1,
y = (-1)∧-3
= -1
The point that correspond to t=-1 is (-3,-1).
Answer: I just took the test and got 100%
1. C, the parameter is t and the curve contains the set of points (2cos(t), sin(t)
2. B, up to the left and then up to the right
3. D, (-3,-1)

Answer:
Divide total length by length of each piece to get the number of pieces.
= 30 ÷ 2/3
multiply by reciprocal of 2/3
= 30 * 3/2
= 90/2
= 45
