When you divide a whole number by a whole number( other then one), the quotient is a smaller number?

Ostrovityanka [42]

Yes because division always makes numbers smaller. For example: 12 divided by 4 equals 3.

Pie

Answer:

• Slope is the derivative of the function:

${ \rm{f(x) = {x}^{3} + 3 {x}^{2} + 3x + 1 }} \\ \\ { \tt{ \frac{dy}{dx} = 3 {x}^{2} + 6x + 3 + 0 }}$

• At, x = 0

${ \tt{ \frac{dy}{dx} = 3 {(0)}^{2} + 6(0) + 3}} \\ \\ { \boxed{ \tt{slope = 3}}}$

Step-by-step explanation:

The method of Lagrange multipliers can solve this quickly. For objective function f(x, y) and constraint function g(x, y)=0 we can set the partial derivatives of the Lagrangian to zero to find the values of the variables at the extreme of interest.

These functions are ...

$f(x,y)=4x+2y\\g(x,y)=2x^2+y-4$

The Lagrangian is ...

$\mathcal{L}(x,y,\lambda)=f(x,y)+\lambda g(x,y)\\\\\text{and the partial derivatives are ...}\\\\\dfrac{\partial \mathcal{L}}{\partial x}=\dfrac{\partial f}{\partial x}+\lambda\dfrac{\partial g}{\partial x}=4+\lambda (4x)=0\ \implies\ x=\dfrac{-1}{\lambda}\\\\\dfrac{\partial \mathcal{L}}{\partial y}=\dfrac{\partial f}{\partial y}+\lambda\dfrac{\partial g}{\partial y}=2+\lambda (1)=0\ \implies\ \lambda=-2$

$\dfrac{\partial\mathcal{L}}{\partial\lambda}=\dfrac{\partial f}{\partial\lambda}+\lambda\dfrac{\partial g}{\partial\lambda}=0+2x^2+y-4=0\ \implies\ y=4-2x^2\\\\\text{We know $\lambda$, so we can find x and y:}\\\\x=\dfrac{-1}{-2}=0.5\\\\y=4-2\cdot 0.5^2=3.5$
