#9) Terry determined the relationship between the water level of a river and temperature.
The graph shows the water level as a
function of x, the temperature. Which
answer choice best describes the domain
and range of the function for this
situation?
A) Domain: (20)
Range: (100)
B) Domain: (100)
Rangle: (20)
10 12 14 16 18 20
C) Domain: All real numbers greater than or equal to 0 and less than or equal to 100.
Range: All real numbers greater than or equal to 0 and less than or equal to 20.
D) Domain: All real numbers greater than or equal to 0 and less than or equal to 20.
Range: All real numbers greater than or equal to 0 and less than or equal to 100.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
