Melanie has 137 dollars in total.
Let each book cost=x
No of books=17
So total cost of 17 books=17x
After buying books Melanie left with 11 dollars
According to question the required equation will be=
17x+11=137
17x=137-11=126
x=8
i.e Price of each book is 8 dollars. (Answer)

The movement of the particle on the circle is its displacement.
The value of dy/dt at this time is -9/2.
<h3>What is the differentiation?</h3>
Differentiation is a process, in Maths, where we find the instantaneous rate of change in function based on one of its variables.
A particle moves on the circle x^2 + y^2=25 in the XY-plane for time t≥0. At the time when the particle is at the point (3,4), dxdt=6.
The equation of the circle is given as:

Differentiate with respect to time

Substitute all the values in the equation

Hence, the value of dy/dt at this time is -9/2.
