Answer:
x = {- 4, 4}
Step-by-step explanation:
factored polynomial is: (x–4)(x+4)
Let (x–4)(x+4) = 0
Answer:
Use ten digits ( 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 ), and let 30% of them represent adults with college degrees.
Find the probability that a 0, 1, or 2 is not generated within the first two random picks.
Step-by-step explanation:
Both of them are randomized and that is what the question means.
Your question asks for an expression, so you would expect an answer in the form of an equation containing variables. This is because you have only 2 independent equations with 3 unknowns. That makes the system unsolvable.
Suppose v₁ is the mountaineer's velocity during the 1,000-foot trail. Then, v₂ is his speed for the 5,000-foot trail. The equation relating these two variables is:
v₂ = 2v₁ - 10 ---> equation 1
Then, you find the equation for the total number of hours he climbed. That would be the distance divided by their respective speed.
t = 1000/v₁ + 5000/v₂ ----> equation 2
Substituting equation 1 to equation 2,
t = 1000/v₁ + 5000/(2v₁ - 10)
t = 1000/v₁ + 5000/2(v₁-5)
t = 1,000/v₁ + 2,500/(v₁-5)
