Create and answer your

shutvik [7]

Step-by-step explanation:

$\frac{20}{48} \times \frac{80}{44}$

Divide the fraction with 4

$\frac{20÷4}{48÷4} \times \frac{80÷4}{44÷4} = \frac{5}{12} \times \frac{20}{11}$

Reduce the number with factor 4

$\frac{5}{12÷4} \times \frac{20÷4}{11} = \frac{5}{3} \times \frac{5}{11}$

Multiply the fractions

$\frac{5 \times 5}{3 \times 11} = \frac{25}{33}$

$\boxed{\green{= \frac{25}{33} = 0.75}}$

This extreme value problem has a solution with both a maximum value and a minimum value. use lagrange multipliers to find the ex

noname [10]

$L(x,y,z,\lambda)=10x+10y+2z+\lambda(5x^2+5y^2+2z^2-42)$

$L_x=10+10\lambda x=0\implies1+\lambda x=0$

$L_y=10+10\lambda y=0\implies1+\lambda y=0$

$L_z=2+4\lambda z=0\implies1+2\lambda z=0$

$L_\lambda=5x^2+5y^2+2z^2-42=0$

$\begin{cases}L_x=0\\L_y=0\\L_z=0\end{cases}\implies1+\lambda x=1+\lambda y=1+2\lambda z=0\implies x=y=2z$

$5x^2+5y^2+2z^2=5(2z)^2+5(2z)^2+2z^2=42z^2=42\implies z^2=1$

$z^2=1\implies z=\pm1\implies x=y=\pm2$

There are two critical points, at which we have

$f\left(2,2,1\right)=42\text{ (a maximum value)}$

$f\left(-2,-2,-1\right)=-42\text{ (a minimum value)}$
