Awire of length 14 is cut into two pieces which are then bent into the shape of a circle of radius r and a square of side s. then the total area enclosed by the circle and square is the following function of s and r
if we solve for s in terms of r, we can reexpress this area as the following function of r alone:
thus we find that to obtain maximal area we should let r =
to obtain minimal area we should let r =

Answer is shown in the attachment you can see.

Step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
