Match the parametric equations with the verbal descriptions of the surfaces by putting the letter of the verbal description to the left of the letter of the parametric equation. d 1. r(u, v)=ui+cosvj+sinvk 2. r(u, v)=ui+vj+(2u−3v)k 3. r(u, v)=ui+ucosvj+usinvk 4. r(u, v)=ucosvi+usinvj+u2k

the answer is: the length is 5/6 yards.

give me a or a 5 star rating if this is correct!

step-by-step explanation:

y > 1/3x

y < = -x + 4

hope this : )

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
