Answer:
-22z
Step-by-step explanation:
-8z - 14z = -22z // Addition ( - - = +)
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
A•a^7 = a^8 (add the power (n=1+7=8))
Answer:
the third option would be the best
Step-by-step explanation:
2/7 + 3/8 = 37/56 = .660
1/10 + 3/8 = 19/40 = .475
correct answer------------ 1/6 + 1/8 = 7/24 = .291
2/9 + 1/8 = 25/72 = .347
50 because their product is equal to and the sum is equal to
