What are the amplitude and midline? amplitude: 1; midline: y = 1 amplitude: 1; midline: y = 2 amplitude: 2; midline: y = 1 amplitude: 2; midline: y = 2

D) Amplitude;2 ; midline: y= 2

Step-by-step explanation:

The total height of the curve = 4

Amplitude = 4/2 = 2

The middle line is y = 2

Therefore, answer is D) Amplitude;2 ; midline: y= 2

Hope this will helpful.

Thank you.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
