Graph each pair of parametric equations. (2 points each)

x = 3 sin3t
y = 3 cos3t

x = 7 sin t + sin 7t
y = 7 cos t + cos 7t

x = 2t
y = t + 5, -2 ≤ t ≤ 3

x = 2t – 1
y = t2 + 5, -4 ≤ t ≤ 4

x = 6 sin t
y = 6 cos t, 0 ≤ t ≤ 2π

want you to answer that problem hahaha

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.
