Answer with Step-by-step explanation:
We are given that a function
a.We have to find the inverse of m.
Suppose,
Replace x by y and y by x
Substitute
b.When the inverse function of given function is
Then , we get fog(x)=
When f and g are inverse to each other then fog(x)=Identity function.
c.If f(x)=x
It is self inverse function.
Answer:
The minimum labor = 270 hours and it is obtained when 0 units of plants and 18 animals are collected.
Step-by-step explanation:
We assume that x should represent the number of units of plants
Also y to represent the number of animals.
So, minimze (z) = 30 x + 15 y
Subject to:
30 x + 20 y ≥ 360
10 x + 25 y ≥ 300
y ≤ 8
0 ≤ x ≤ 25
0 ≤ y ≤ 25
Changing the above linear inequalities into linear equation; we have:
30 x + 20 y = 360
10 x + 25 y = 300
y = 8
The graph for the above discussion can be located in the attached diagrammatic expression below:
NOW, the corner points (0,18),(0,25),(25,25), and (25,8) can be calculated from the graph. From the diagram, the corner point can be found by solving the system.
30 x + 20 y = 360
10 x + 25 y = 300
Corner point (10, 8) = 10 x + 25 y = 300
y = 8
Corner point Value of z = 30 x + 15 y
(0,18) 270
(0,25) 375
(25,25) 1125
(25,8) 870
≅ 310.91
(10, 8) 420
∴
The minimum labor = 270 hours and it is obtained when 0 units of plants and 18 animals are collected.
