Anna is drawing the midsegment of δ lnm that is parallel to ln. what are the coordinates of the endpoints of the midsegment? a) (3, 4) and (3, 7) b) (4, 4) and (4, 7) c) (2, 7) and (2, 3.5) d) (4, 7) and (4, 3.5)

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).

Given: ac and db are diameters. m∠3=

Δabc is reflected across line l to form δ alblcl, and a¯¯¯al¯¯¯¯ intersects line l at point d. which equation is not necessarily true?
