Evelyn walks on a treadmill for at least 1 hour but not more than 2 hours. she walks at an average rate of 3.5 miles per hour. the distance evelyn walks in t hours is represented by a function. r(t)=3.5tr(t)=3.5t what is the practical domain of the function? all real numbers from 1 to 2, inclusive. all real numbers. all integers from 1 to 2, inclusive. all multiples of 3.5 between 3.5 and 7, inclusive.

The answer is all real numbers from 1 to 2, inclusive.

It states that Evelyn walks on a treadmill for at least an hour. That means that Evelyn does not stop walking unless she reaches the 1st hour. It also states that it does not take her more than 2 hours, meaning, her limit is 2 hours. Thus, she may walk for 1-2 hours, inclusive.  

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
