Answer: 2< x < 10, closed circle at 2 and 10, line inbetween them
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
A is a horizontal line on 3
B will cross the y axis at (0, -3), and the x axis (3, 0)
D will cross the y axis (0, 1) and the x axis (-0.5, 0)
As C does not have a y-intercept or x-intercept, it will it (0, 0)

Answer: the computer towers will be worth $10521 after 8 years
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
A = P(1 - r)^t
Where
A represents the value of the computer towers after t years.
t represents the number of years.
P represents the initial value of the computer towers.
r represents rate of decay.
From the information given,
P = $30900
r = 12.6% = 12.6/100 = 0.126
Therefore, the function that models the value of the computer towers after (t)years from now is
A = 30900(1 - 0.126)^t
A = 30900(0.874)^t
Therefore, when t = 8 years, then
A = 30900(0.874)^8
A = $10521
