When x=-1: 

Ok that gives us a little more information.
If we implicitly differentiate with respect to t, from the very start, then we can apply our product rule, ya?

The right side is zero, derivative of a constant is zero.
Where x' is dx/dt and y' is dy/dt.
From here, plug in all the stuff you know:
y' = -3
x = -1
y = 4
and solve for x'.
Hope that helps!

Answer:
7.85 ft
Step-by-step explanation:
This question is asking you to find the circumference of the circle. To do this the equation is C= D where C is circumference and D is diameter. So, C= 3.14* 2.5 which equals 7.85 ft.
D where C is circumference and D is diameter. So, C= 3.14* 2.5 which equals 7.85 ft.
