These two graphs represent and selection. A histogram with x-axis from 0 to 50 and y-axis from 0 to 100. Bars steadily increase from (40, 5) to (24.84, 55) and then steadily decrease to (40, 3). A histogram with x-axis from 0 to 50 and y-axis from 0 to 100. Bars increase quickly then decrease, increase again, and decrease quickly. a. directional; stabilizing b. stabilizing; disruptive c. disruptive; static d. static; directional Please select the best answer from the choices provided A B C D

B.

Step-by-step explanation: Got it right on quiz.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

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)

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