Answer: 5 \dfrac{13}{20}\ \text{miles}

Step-by-step explanation:

Given

George walks 3 \frac{1}{4} before taking break

then he walks additional 2 \frac{2}{5} miles

total distance walked

\Rightarrow 3 \frac{1}{4}+2 \frac{2}{5}=\frac{12+1}{4}+\frac{10+2}{5}\\\Rightarrow \frac{13}{4}+\frac{12}{5}=\frac{13\times 5+12\times 4}{20}\\\Rightarrow \frac{113}{20}=5 \frac{13}{20}\ \text{miles}

Find all points on the portion of the plane x+y+z=5 in the first octant at which f(x, y, z) = xy2z2 has a maximum value.
irina1246 [14]
Lagrange multipliers:

L(x,y,z,\lambda)=xy^2z^2+\lambda(x+y+z-5)

L_x=y^2z^2+\lambda=0
L_y=2xyz^2+\lambda=0
L_z=2xy^2z+\lambda=0
L_\lambda=x+y+z-5=0

\lambda=-y^2z^2=-2xyz^2=-2xy^2z

-y^2z^2=-2xyz^2\implies y=2x (if y,z\neq0)

-y^2z^2=-2xy^2z\implies z=2x (if y,z\neq0)

-2xyz^2=-2xy^2z\implies z=y (if x,y,z\neq0)

In the first octant, we assume x,y,z>0, so we can ignore the caveats above. Now,

x+y+z=5\iff x+2x+2x=5x=5\implies x=1\implies y=z=2

so that the only critical point in the region of interest is (1, 2, 2), for which we get a maximum value of f(1,2,2)=16.

We also need to check the boundary of the region, i.e. the intersection of x+y+z=5 with the three coordinate axes. But in each case, we would end up setting at least one of the variables to 0, which would force f(x,y,z)=0, so the point we found is the only extremum.

Answer:

Line BC

Step-by-step explanation:

Opposite means whatever is exactly parallel to angle a.

In this case, we notice BC to satisfy that rule.

Hope this helps.

anygoal [31]

Answer:

Sample Response: First, the like terms had to be combined using the lowest common denominator (LCD). Then the subtraction property of equality was used to isolate the variable term. Finally, both sides of the equation were multiplied by the reciprocal of the coefficient to solve for a.
