Answer:
the question is incomplete, the complete question is
"Finding Derivatives Implicity In Exercise,Find dy/dx implicity .
"
Answer : 
Step-by-step explanation:
From the expression
" y is define as an implicit function of x, hence we differentiate each term of the equation with respect to x.
we arrive at

for the expression
we differentiate using the product rule, also since y^2 is a function of y which itself is a function of x, we have
.
if we make dy/dx subject of formula we arrive at

If
, then by rationalizing the denominator we can rewrite

Now,

and



7.855 mm maybe the answer unless rounded to the tenths place to be 7.9 mm.
By the mid point formula is my best guess
