a store had 50 bottles of olive oil. each week, 40% of the olive oil bottles were sold and 20 new bottles arrived in shipments. which recursive function best represents the number of bottles in the store, given that f(0) = 50?
f(n) = f(n − 1) ⋅ 0.6 + 20, n > 0
f(n) = 50 − f(n − 1) ⋅ 0.6 + 20, n > 0
f(n) = 50 − f(n − 1) ⋅ 0.4 + 20, n > 0
f(n) = f(n − 1) ⋅ 0.4 + 20, n > 0

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.

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

step-by-step explanation:

the answer is 89 d
