Aliyah and Diego started to run in a 5 kilometer-long race at exactly the same time. By 3:00 P. M., Aliyah had completed half of the race. For the rest of the race, Aliyah ran at a constant rate of 0.25 kilometer per minute. Diego did not run the race at a constant speed. A linear function can be used to model the total distance d(t)d(t) , in kilometers, that Aliyah runs from the beginning of the race in t minutes, where t=0t=0 represents 3:00 P. M. Write an equation that defines the linear function d. Explain how you determined the equation for the function.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

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
