Answer:
a.
b.
Step-by-step explanation:
To solve this question, we apply implicit differentiation.
xy = 2
Applying the implicit differentiation:
a. Find dy/dt, when x = 4, given that dx/dt = 13.
x = 4
So
Then
b. Find dx/dt, when x = 1, given that dy/dt = -9.
x = 1
So
Then

Answer:
So , the correct option is the diagonals are angle bisectors which is not a characteristic of all parallelograms.
Step-by-step explanation:
The properties of parallelograms are as follows:
i) the diagonals of a parallelogram bisect each other
ii) opposite sides are congruent
iii) opposite angles are congruent
iv) consecutive angles are supplementary
v) the diagonals are angle bisectors only if all the sides of the parallelogram are equal.
So , the correct option is the diagonals are angle bisectors which is not a characteristic of all parallelograms.
