Astore had 100 t-shirts. each month, 30% of the t-shirts were sold and 25 new t-shirts arrived in shipments. which recursive function best represents the number of t-shirts in the store, given that f(0) = 100?

choices:
a. f(n) = f(n − 1) ⋅ 0.3 + 25, n > 0
b. f(n) = 100 − f(n − 1) ⋅ 0.3 + 25, n > 0
c. f(n) = f(n − 1) ⋅ 0.7 + 25, n > 0
d. f(n) = 100 − f(n − 1) ⋅ 0.7 + 25, n > 0

D. f(n) = 100 − f(n − 1) ⋅ 0.7 + 25, n > 0

Its D I took the test and got it right

Step-by-step explanation:

-8

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
