A particle moves in a straight line with velocity v(t) = 8 –t meters per second, where t is time in seconds. At t = 4, the particle's distance from the starting point was 3 meters. What is the total
distance the particle has traveled between t = 4 and t = 10 seconds?
Which expression should she use to solve the problem?

tangent

step-by-step explanation:

c > -10.55

step-by-step explanation:

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
