Answer:
Below.
Step-by-step explanation:
a. Φ^2 − Φ − 1 = 0
Φ2 − Φ = 1
(Φ - 0.5)^2 - 0.25 = 1
(Φ - 0.5)^2 = 1.25
Φ - 0.5 = √(1.25) (We only take the positive root).
Φ = 0.5 + √(1.25)
b. I used Completing the square.
c. Φ is irrational That is it cannot be represented as a fraction a/b and because of this it can only be approximated by a decimal.
Answer:
I'm pretty sure it is D because they're not super close to the line they're more spread out but I'm not rly sure
(5/4)•(4/3)•(3/5)
So you multiply all of them basically
You have to set it up as two problems then combined like terms then add them together
