1 Select the correct answer.
On average, Adrian's salary is 1.05 times the previous year's salary
If Adrian initially has $52,000 and n denotes the number of years, which recursive equation gives Adrian's annual income, f(n),
the year?
as a functior
OA. f(1) = 52,000
f(n) = 1.05 · f(n − 1), for n > 2
OB. f(1) = 52,000
f(n) = 1.05 + f(n − 1), for n > 2
OC f(1) = 1.05
f(n) = 52,000 + f(nr – 1), for n > 2
OD. f(1) = 1.05
f(n) = 52,000 . f(n − 1), for n > 2

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
