Further mathematics: Find the derivative of the function x^2 y + (xy)^3 +3x=0 at (-1 , 3)

vesna_86 [32]

Answer:

Step-by-step explanation:

Implicit differentiation:

x^2 y + (xy)^3 + 3x = 0

x^2 y + x^3y^3 + 3x = 0

Using the product rule:

2x* y + x^2*dy/dx + 3x^2 y^3 + x^3* (d(y^3)/dx) + 3 = 0

2xy + x^2 dy/dx + 3x^2 y^3 + x^3* 3y^2 dy/dx + 3 = 0

dy/dx(x^2 + 3y^2x^3) = (-2xy - 3x^2y^3 - 3)

dy/dx= (-2xy - 3x^2y^3 - 3) / (x^2 + 3y^2x^3)

At the point (-1, 3).

the derivative = (6 - 81 - 3)/(1 -27)

= -78/-26

= 3.

anyanavicka [17]

The miller needs 1-3/4 kg (or 1.75 kg) for two loaves.
Therefore the amount of flour needed for 1 loaf is
1.75/2 = 0.875 kg per loaf.

For 8 loaves, the amount of flour needed is
8*0.875 = 7 kg

Answer: 7 kg of flour is needed for 8 loaves.

Solve x/5 - 1=7? help please !!

xxTIMURxx [149]

First, add 1 on both sides of the equation to begin to isolate x

x/5 = 8

Now, to isolate x, multiply both sides of the equation by 5/1

$\frac{x}{5}$ · $\frac{5}{1}$ = $\frac{5x}{5}$ = x

x= 7 · 5/1 = 7 · 5 = 35

x = 35
