A normal resting heart rate for adults ranges from 60 to 100 beats per minute. If a heart beats fewer than 60 times a minute, that person has “bradycardia (brad-e-KAHR-dee-uh). It’s normal for a heart to beat faster during
exercise, but if a heart beats over 100 beats per minute at rest, that person has “tachycardia” (ta·kuh·KAHR·dee·uh).
Both bradycardia and tachycardia are abnormal heart rhythms, and a doctor should be consulted.
1. Write a combined inequality that shows normal resting heart rate. Graph that inequality.

the thermometer is precise but not accurate

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

c
