gogolik [260]3 years ago
4 0

Step-by-step explanation:

An equation involving x and y, which is also a function, can be written in the form y = “some expression involving x”; that is, y = f ( x). This last expression is read as “ y equals f of x” and means that y is a function of x.

Graph the feasibility region represented by the given inequalities and find the maximum profit if P = 4x + 5y. x ≥ 5 y ≤ 10 2x -
Brilliant_brown [7]

First, graph the three inequalities:  x ≥ 5  ,  y ≤ 10  ,  2x - y  ≤ 8

Next, look for the 3 intersections (vertices) of the lines: (5, 2)  ,  (5, 10)   ,  (9, 10)

Finally, input the vertex coordinates into P = 4x + 5y and look for the biggest #.

(5, 2):  4(5) + 5(2)  = 20 + 10  = 30

(5, 10): 4(5) + 5(10)  = 20 + 50  = 70

(9, 10): 4(9) + 5(10)  = 36 + 50  = 86

Answer: maximum profit = 86

The figure below shows the ideal pattern of movement of a herd of cattle, with the arrows showing the movement of the handler as
Lyrx [107]

Answer:

133.45

Step-by-step explanation:

They are looking for arc length. The formula is

\frac{n}{360} * 2πr

a quarter circle is 90°, so put 90 for n. 85 is the radius, so put that for r.

\frac{90}{360} * 2 π (85)
