ow far does the first car go in the 2 hours head start it gets? Now, at t = 2 hours, both cars are moving. How much faster is the second car than the first car? How long will it take to recover the head start? You can determine this by dividing the head start by the difference in the two speeds. If car 1 has a 20 mile head start, and car 2 is 5 mph faster, then it will take 20/5 = 4 hours to catch up.

You could also write two equations, one for each car, showing how far they have gone in a variable amount of time. Set the two equations equal to each other and solve for the value of the time. Note that the second car's equation will use (t-2) for the time, because it doesn't start driving until t = 2.

Keefe was mad at Fitz so he decided to plan revenge. He had 5.3 liters of feces but he wanted to us only 1/4 of it. In that 1/4 of the amount, 0.4 of the feces was alicorn ones and 0.6 of it was gulon feces. How many Liters did Keefe use? How many liters of alicorn feces were there and how many liters of gulon feces were there in the amount that he used?

Answer:

The possible rational roots are: +1, -1 ,+3, -3, +9, -9

Step-by-step explanation:

The Rational Root Theorem tells us that the possible rational roots of the polynomial are given by all possible quotients formed by factors of the constant term of the polynomial (usually listed as last when written in standard form), divided by possible factors of the polynomial's leading coefficient. And also that we need to consider both the positive and negative forms of such quotients.

So we start noticing that since the leading term of this polynomial is $x^3$ , the leading coefficient is "1", and therefore the list of factors for this is: +1, -1
