Lucy is running a test on her car engine that requires her car to be moving. The tolerance for the variation in her car’s speed, in miles/hour, while running the test is given by the inequality |x − 60| ≤ 3. Assume x is the actual speed of the car at any time during the test.

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.

hello! just here for points! though i wish i knew!

x = -5
