A store had 250 bottles of water. Each week, 40% of the bottles were sold and 48 new bottles arrived in shipments. Which recursive function best represents the number of bottles of water in the store, given that f(0) = 250? f(n) = f(n − 1) ⋅ 0.6 + 48, n > 0 f(n) = 250 − f(n − 1) ⋅ 0.4 + 48, n > 0 f(n) = f(n − 1) ⋅ 0.4 + 48, n > 0 f(n) = 250 − f(n − 1) ⋅ 0.6 + 48, n > 0

step-by-step explanation:

pleaze mark brainliest!

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
