<span>0.002
is the 1/10 of what number.
Find the number that applies to this.
=> 0.002 has a thousandths value since it is placed next to the decimal
points
=> To be able to get the answer. Let’s convert 1/10 into a decimal.
=> 1 / 10 = 0.1
Now that we have the same decimal numbers, we can now start dividing 0.1 to
0.002
=> 0.002 / 0.1
=> 0.02
Thus, 0.002 is the 1/10 of 0.02 number.</span><span>

Answer:
I think it's D but I am not sure.
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!
