Find the values of x and y that maximize the objective function P=3x+2y for the graph. What is the maximum value?
AURORKA [14]

Answer:

(9, 0)

Step-by-step explanation:

Maximum or minimum value occurs at the Corner. The points given are (0, 8), (5, 4) and (9, 0).

Substitute (0, 8) in the objective function.

We get P = 3(0) + 2(8) = 16

Now for (x , y) = (5, 4)

P = 3(5) + 2(4) = 15 + 8 = 23

At (9, 0) we get P = 3(9) + 2(0) = 27.

Clearly, we have the maximum value at (9, 0).

And the maximum value is 27.

A triangle has two sides measuring 16 and 21. The included angle is 116°. What is the length of the side opposite the 116° angle
lutik1710 [3]

Answer:

h =26.4

C is correct Option

Step-by-step explanation:

Let,

Base of the triangle = b = 16  

Perpendicular of the triangle = p = 21

Hypotenuse of the triangle= h = ?

According to Pythagoras theorem;

 h^{2} = b^{2} +p^{2}

 h^{2} = 21^{2} +16^{2}

 h^{2} =441+256

 h^{2} =697

 h =\sqrt{697}

h =26.4
