Evaluate the piecewise-defined function for the indicated values. Q(t) = 9, if 0 ≤ t ≤ 5 −t + 5 if 5 < t ≤ 8 t − 1 , if 8 < t ≤ 11

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

f is the midpoint of

cheater

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
