Height: a six-foot person walks from the base of a
broadcastingtower directly toward the tip of the shadow cast by the
tower. whenthe person is 132 feet from the tower and 3 feet from
the tip ofthe shadow, the person's shadow starts to appear beyond
the tower'sshadow.

a) draw a right triangle that gives a visual representation of
theproblem. show the known qualities of the triangle and use
avariable to indicate the height of the tower.

b) use a trigonometric function to write an equation involving
theunknown quality.

c) what is the height of the tower?

what is the question here

step-by-step explanation:

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

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
