The solution is A
x=2 y=-1
the solution is where the two lines intersect
C = d × pi
C = 6 × 3.14
C = 18.84
Answer:
There is no explanation so I guess 1 to 1?
Step-by-step explanation:
Looks like the given curve is
5<em>xy</em> + <em>z</em>⁴<em>x</em> - 3<em>yz</em> = 3
Differentiate both sides with respect to <em>x</em> :
5<em>y</em> + 4<em>z</em>³<em>x</em> ∂<em>z</em>/∂<em>x</em> + <em>z</em>⁴ - 3<em>y</em> ∂<em>z</em>/∂<em>x</em> = 0
Solve for ∂<em>z</em>/∂<em>x</em> :
(4<em>z</em>³<em>x</em> - 3<em>y</em>) ∂<em>z</em>/∂<em>x</em> = - (5<em>y</em> + <em>z</em>⁴)
∂<em>z</em>/∂<em>x</em> = - (5<em>y</em> + <em>z</em>⁴) / (4<em>z</em>³<em>x</em> - 3<em>y</em>)
At the point (1, 1, 1), this derivative is
∂<em>z</em>/∂<em>x</em> (1, 1, 1) = - (5 + 1) / (4 - 3) = -6
