ABC company wishes to minimize its cost. Its cost is given by the equation C = 3x+4y. The business constraints are as follows:

Answer:
(2, 0)
Step-by-step explanation:
To solve this problem, we have to plot a graph. A graph was plotted using geogebra online graphing calculator. From the attached graph we can see the points that satisfy the constraints: (0,0), (2, 0), (2, 6), (6, 4). But since x,y > 0, this leaves us with B(2, 6), C(2, 0), D(6, 4)
The cost equation is C = 3x + 4y
At point B(2, 6): C = 3(2) + 4(6) = 30
At point C(2, 0): C = 3(2) + 4(0) = 6
At point D(6, 4): C = 3(6) + 4(4) = 34
Therefore the minimum cost is at C(2, 0)

Answer:
219m
Step-by-step explanation:
Since the man observes the car with angle 15 before observing in 33 degrees.
For the first observation
The angle observation gives an angle if 33 degrees with the horizontal.
It gives a triangle which I'll attach to the que,
from the first triangle
Tan 33 = 100/y
Y= 100/ tan 33
Y = 153.99m.
This is the distance from the building to the distance where it was secondly observed( 33).
To find x
tan 15 = 100/(153.99+x)
153.99 + x = 100/ tan 15
153.99 + x = 373.21
The distance between the two observed angles
X= 219m.
