If a car is depreciating by 12%, what will the multiplier for the exponential function be?

0.88

Step-by-step explanation:

Given data

Rate of depreciation = 12%

The expression for the exponential function is given as

A= P(1-r)^t

r= 0.12

A= P(1-0.12)^t

A= P(0.88)^t

Hence as seen from the expression, the multiplier is 0.88

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.
