The percent of usage of the word judgment in books can be modeled with an exponential decay curve. let p be the
percent as a function of x, and let x be the number of years after 1900; then, p(x) = 0.0 220 465 ⋅ e^−0.0 079 941x.
a. according to the model, in what year was the usage 0.1% of books?
b. when does the usage of the word judgment drop below 0.001% of books? this model was made with data
from 1950 to 2005. do you believe your answer is accurate? explain.
c. find pp−1. what does the domain represent? what does the range represent?

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8

step-by-step explanation:

my dear correct answer is option number 3

this is a good question! i'll do some research and come back when i have the answer!
