2. 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 78,000 cubic yards. what function models the amount of fertilizer in cubic yards left after w weeks?

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

Step by step explanation:

The amount of fertilizer in the landscaping company's warehouse decreases by 3% per week

So,

3% ------> .03

now we subtract .03 from 1 and we get .97

1 - .03 = .97

and the function would look like this:

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

I have uploaded a pic to make it a little clearer. Hope it helps :-)

God bless

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
