Aparticle moves along the curve below. y = 8 + x3 as it reaches the point (1, 3), the y-coordinate is increasing at a rate of 3 cm/s. how fast is the x-coordinate of the point changing at that instant?

Change of rate of x coordinate=1 cm/s

Step-by-step explanation:

Given that

Now differentiate with respect to time in both side

So

Given  that y-coordinate is increasing at a rate of 3 cm/s

So

Also given that coordinates (1,3)

So x=1

Now by putting the values

So  

Change of rate of x coordinate=1 cm/s

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees
