For positive integer n, the factorial notation n! represents the product of the integers from n to 1. (For example, 6! = 6.5.4.3.2.1.) What value of N satisfies the following equation?
5! . 9! = 12. N!
9
(A) 10
(B) 11
(C) 12
(D) 13
(E 14

rounding to the nearest thousandth would be 452,000

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
