Step-by-step explanation:
Given equation of circle is,
again the another form of circle is,
now equating the values of f in both equations,
-k=-3
i.e. k=3
therefore k=3
Becaue the ones add up to 10 or more, they will regroup and put a 1 above the tens column to show the 10.
The principal should buy 8 of type A and 3 of type B to get the largest possible storage space for books
<h3>How to determine the number and type of book cases?</h3>
Let x represent type A and y represent type B,
So, we have the following table:
x y Available
Floor space 0.6 0.8 7.2
Budget 10 20 140
Book hold 0.8 1.2
Using the above table, we have the following linear model
Objective function Min Z = 0.8x + 1.2y
Subject to
0.6x + 0.8y ≤ 7.2
10x + 20y ≤ 140
x, y > 0
Using a graph, the solution to the above system of inequalities is:
(x,y) = (8,3)
Hence, the principal should buy 8 of type A and 3 of type B to get the largest possible storage space for books
