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. Which function models the
amount of fertilizer in cubic yards left after w weeks?
A. f(w) = 0.97(78,000)w
B. f(w) = 1.03(78,000)w
C. f(w) = 78,000(0.97)W
D. f(w) = 78,000(1.03)W

how am i supposed to answer

step-by-step explanation:

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
