Given the following parametric equations, determine the coordinates of
the curve when t=60°.

x=2t
y= -3t
show all work.

Step-by-step explanation:

The given parametric equation is

x=2t  

y= -3t

The coordinates of any point lying on this curve can be obtained by substituting the parameter value.

Given the parameter value, t=60

We have

and

Therefore the point

lie on this parametric curve.

1. TRUE
2. false - compare to 3.
3. TRUE - compare to 4.
4. TRUE - the sum of exernal angles of any convex polygon is 360°
5. false - compare to 4.
6. false - compare to 7.
7. TRUE - the angles are supplementary
8. false - compare to 4.

The true statements are 1, 3, 4, 7.
