In 2000, 55 % of the residents in a large city regularly used newspapers for getting news and this has decreased at an average rate of approximately 1.7 % per year since then. find a linear function in slope-intercept form that models this description. the function should model the percentage of residents, upper p (x )comma who regularly used the news outlet x years after 2000.

P(x) = - 1.7x + 55

Step-by-step explanation:

x denotes the years that have passed since 2000. So for year 2000, x =  0

Therefore we have that when x₁ = 0, y₁ = 55. From the information given by the problem we know that the slope m is -1.7.

So by substituting these values in the formula y-y₁ = m( x - x₁) we get:

y - 55 = -1.7 (x - 0)

y - 55 = -1.7x

y = - 1.7x + 55

Thus our function P(x) that models the percentage of residents who regularly used the news outlet x years after 2000 is

P(x) = -1.7x + 55

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
