Answer:
y^2+2xy/-x^2-2xy OR -y^2-2xy/x^2+2xy OR -y^2-2xy/(x)(x+2y)
Step-by-step explanation:
So, this is an implicit differentiation problem
x^2y+y^2x
so,
use product rule for both
x^2y'+2xy+y^2+2yy'x
collect all the y's
-x^2y'-2xyy'=y^2+2xy
y'(-x^2-2xy)=y^2+2xy
=y^2+2xy/-x^2-2xy

Answer:
A = 33.33
Step-by-step explanation:
P = 0.006A^2 - 0.02A + 120
*** P = 126 ***
126 = 0.006A^2 - 0.02A + 120
126 = (3/500)A^2 - (1/50)A + 120
*** multiplied with 500 on both sides ***
63000 = 3A^2 - 10A + 60000
63000 - 3A^2 + 10A - 60000 = 0
3000 - 3A^2 + 10A = 0
3A^2 - 10A - 3000 = 0
3A^2 + 90A - 100A - 3000 = 0
3A(A + 30) - 100(A + 30) = 0
(A + 30)(3A - 100) = 0
A + 30 = 0 | 3A - 100 = 0
A = -30 | 3A = 100
A = -30 | A = 100/3
Human age cannot be negative so
A = 100/3 = 33.33
