Asap! (and explain thoroughly) i will give brainliest!

what point in the feasible region maximizes the objective function?
constraints:
{ x ≥ 0
{ y ≥ 0
{ − x + 3 ≥ y
{ y ≤ 1/3 x + 1

objective function: c = 5 x – 4 y

1. Draw all graphs and determine the shaded region:

a) for  you should take 1 and 4 quadrants (including y-axis);

b) for  you should take 1 and 2 quadrants (including x-axis);

c) for  you should draw the graph of the line y=-x+3 and take the bottom half-plane;

d) for  you should draw the graph of the line y=1/3x+1 and take the bottom half-plane.

Then the intersection of all shaded parts is needed shaded region, quadrilateral OABC (see diagram for details).

2. Th graphs of the lines C=5x-4y will intersect this shaded region at different points. The maximum of the function could be only at vertices.

3. Find the coordinates of all vertices:

a) O(0,0) - the origin;

b) A(0,1) - the y-intercept of line y=-x+3;

c) C(3,0) - the x-intercept of line y=1/3x+1;

d) B: solve the system y=1/3x+1, y=-x+3.

-x+3=1/3x+1,

-x-1/3x=1-3,

-4/3x=-2,

x=3/2,

y=-3/2+3=3/2,

then B(3/2,3/2).

4) F(x)=5x-4y and

F(O)=0,

F(A)=5·0-4·1=-4,

F(C)=5·3-4·0=15,

F(B)=5·3/2-4·3/2=7.5-6=1.5

The maximal value of F is at point C.

Maximum value is 15 at point (3,0)

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
