PLEASE HELP! WILL ADD BRAINLIEST!! The amount of fertilizer in a landscaping company's warehouse decreases at a rate of 3% per week. The Amount of fertilizer in the warehouse was originally 78,00 cubic yards

Which Function models the amount of fertilizer in cubic yards left after "w" weeks

f(w)= 0.97 (78,000)^w
f(w)= 1.03 (78,000)^w
f(w)= 78,000 (0.97)^w
f(w)=78,000 (1.03)^w

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

(x) - (y) = (1 + 4i)

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
