4) Use the situation to choose the correct answer. The population of a small town on January 1, 2005, was 7,200. On January 1, 2006,
the population was 7,416. on January 1, 2007, the population became 7,639, and on
January 1, 2008 the population was 7,867,
Which of the following equations best models the exponential function of this situation?
OP(t) = 7, 200(0.97)
O P(1) - 0.3(7,200)
O P(1) - 7,200(1.03)
OP() = 7, 200(0,03)

Step-by-step explanation:

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93

hello from mrbilldoesmath!

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

discussion:

in general, the factorization of a^3 + b^3 is

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

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

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

you,

mrb

(a + b) (a^2 - a b + b^2)
