Answer:
The last choice
Step-by-step explanation:
5^2 + 12^2 = 13^2
25 + 144 = 169
The set of rational plus irrational numbers equals ALL REAL NUMBERS
Yes, it is a function because every x-value maps into only one y-value. In other words, because rational and irrational are mutually exclusive, x does not map into both 0 and 1
Domain is all real numbers.
Range is 0 or 1
y-intercept happens when x=0, so that is a rational number and y = 1
There are an infinite number of x-intercepts. Every irrational number is an x-intercept
Neither even or odd because it is not symmetric with either the y-axis or the origin.
The graph jumps between y=0 and y=1

Answer:
x ≈ 32.4
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between angle, adjacent side, and hypotenuse:
Cos = Adjacent/Hypotenuse
cos(72°) = 10/x
x = 10/cos(72°)
x ≈ 32.4
