3 probably it makes the most sense if you ask me
Answer:
(x,y) = (-219/9, -818/9)
Step-by-step explanation:
There is an infinite number of chords in a circle
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.
31/7 = 4 3/7.....3/7 is less then 1/2....so the closest integer is 4
