Hi there!
We can use implicit differentiation with respect to x:
If a term with 'y' is differentiated, a 'dy/dx' must be included.
We can differentiate each term separately for the explanation.
<u>3xy</u>
We must use the power rule since 'x' and 'y' are both in this term.
Power rule:
Now, we can do the others.
<u>4x</u>
This is a normal power rule derivative.
<u>y²</u>
Since we are not differentiating with respect to y, we must include 'dy/dx'.
Combine the above:
Rearrange to solve for dy/dx.
Move dy/dx to one side:
Factor out dy/dx and divide:
ANSWER: TRUE
EXPLANATION: In the middle ear region, there are three bones which are considered to be the tiniest of all bones collectively known as Ossicles. The vibrations of the eardrum are transmitted inward by a chain of the ossicles. These ossicles form a lever system of three stages which turns large movements with little force into smaller motions with greater force. The ossicles amplify tiny changes into air pressures. This proves that sounds in the external ear depends on vibration of movable bones.
