1. a car is traveling at 60 mph and is tailgating another car at distance of only 30 ft. if the
reaction time of the tailgater is 0.5 seconds (time between seeing the brake lights of the
car ahead flash and hitting the brake), how far will his car travel during his reaction time?

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

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

493 would be the correct answer
