Sam has purchased a $30,000 car for his business. the car depreciates 30% every year. what is the explicit formula for this sequence? note: the car is 0 years old when purchased so the first year is the second entry in the sequence.

if your just figuring out how much the car depreciated just by driving off the lot new...1st year.

$30,000×.30=$9,000

$30,000- $9,000=$21,000.

just take the brand new value of the car multiplied by the .30% of the 1st depreciation...take that answer ($9,000) and subtract it from your original value of $31,000.

which gives you $21,000

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.
