Answer:
0.3
Step-by-step explanation:
0.8/y = 2 : 3/4
The value of y in the above expression can be obtained as follow:
0.8/y = 2 : 3/4
0.8/y = 2 ÷ 3/4
0.8/y = 2 × 4/3
0.8/y = 8/3
Cross multiply
0.8 × 3 = y × 8
2.4 = 8y
Divide both side by the coefficient of y i.e 8
y = 2.4/8
y = 0.3
Thus, the value of y is 0.3
Graph the inequalities given by the set of constraints. Find points where the boundary lines intersect to form a polygon. Substitute the coordinates of each point into the objective function and find the one that results in the largest value.
Answer:
I think it's the second one. 5.6487
Step-by-step explanation:
In the first octant, the given plane forms a triangle with vertices corresponding to the plane's intercepts along each axis.
Now that we know the vertices of the surface
, we can parameterize it by
where
and
. The surface element is
With respect to our parameterization, we have
, so the surface integral is
