Step-by-step explanation:
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
Answer: C
Step-by-step explanation:
So, the original fraction is equal to
Answer:
Amount of land = 0.056 hectares
Step-by-step explanation: Given that
An average person in the country needs 2,450 kilocalories / day. That is
A person in a day takes 2450 kilocalories
The average number of kcal per hectare(ha) produced from available food in the country is 15,737,000 kcal/ha.
So in one day per person, we have
15737000 = 2450/hec
Hectare = 2450/15737000
Hectare = 1.5568 × 10 -4
The amount of land that would be needed to produce enough kilocalories to feed a person for one year in this developing country will be
Calculated hectare × 365.25
Hectare = 1.5568 × 10 -4 × 365.25
Amount of land = 0.056 hectares
