Match the graphs of the parametric equations x = f(t) and y = g(t) in (a)- (d) with the parametric curves labeled I-IV.
[G] Find the parametric equations for the curves described below. Then write the corresponding vector-valued function that represents the given curve. Be sure to include an appropriate interval for the parameter. *Make sure you give both the parametric equations and vector- valued function and don't forget the interval for the parameter either. (G.1) The line segment from (-3,4,7) to (6,4,0). (G.2) The segment of the curve with equation y = (x + 4 from (12,4) to (-3,1). (G.3) The lower...

and C2 in the xy-planedefined by the parametric equations Consider trajectories on two curves C1:x=t?, y=t? - <t<«. C2: x = 3t, y=t?, - <t<mo. These two trajectories are known to *intersect* at exactly two points. The origin (0,0) is one of them. And there is another one, which we'll call P. Find Pand select the choice below which gives the slope of the tangent line to the first curve at the point P. Note that only ONE of the...
Consider the following parametric equations. a. Eliminate the parameter to obtain an equation in x and y. b. Describe the curve and indicate the positive orientation. x = (t + 3)2. y=t+5; -10 ≤ t ≤ 10
A bicyclist is interested in the motion of a point on the tread of her tire, so she marks the tread at one point with chalk. She then rides the bike along a flat,level road. She imposes a coordinate system as shown in the figure below such that the chalk mark is touching the ground at the point (0,0) at time t=0. The radius ofher wheels is 35 cm and the bike moves at 70p cm/sec in the direction indicated....
