Match of the equation with the verbal description of the surface would be :
Equation 1 = C. plane
Equation 2 = F. Circular cylinder
Equation 3 = C. plane
Equation 4 = E. sphere
Equation 5 = A. cone
Equation 6 = E. Sphere
Equation 7 = F. Circular cylinder
Equation 8 = B. Eliptic or circular paraboloid
Equation 9 = A. cone
Hope this helps
<span>The correct answer is option A. i.e parallelogram. In a parallelogram, the diagonals bisect each other i.e. one diagonal cuts the other diagonal into equal parts. So, The diagonals of a parallelogram bisect each other. And all the other options, rhombus, rectangle and square are also parallelograms only.</span>

a
Step-by-step explanation:
the second duckling is wandering by 2.6 units distance than the first duckling .
<u>Step-by-step explanation:</u>
Here we have , Two ducklings wander away from the nest while their mother is away. The first duckling's displacement (distance and direction) from the nest is (12,5) The second duckling's displacement is (13,-8) . We need to find How much farther did the second duckling wander than the first duckling. Let's find out:
Let a = (12,5) and b =(13,-8)
The distance each duckling wandered is the magnitude of its displacement vector. Therefore, the expression Distance second duck wandered is given by :
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , the second duckling is wandering by 2.6 units distance than the first duckling .
