Answer:
Step-by-step explanation:
The satellite has 30 modular units.
There are equal numbers of non-upgraded sensors in each unit.
Let us assume that on the entire satellite there are x numbers of upgraded sensors.
Then as per the given condition, there are number of non-upgraded sensors in one unit.
Therefore, the number of non-upgraded sensors on the entire satellite is =6x
Hence, total number of sensors in the satellite is (x+ 6x) =7x
Therefore, the required fraction of the upgraded sensors is . (Answer)
Answer:
The current price is $3000 and price after 9 years from today is $4054.
Step-by-step explanation:
The future price pt(in dollars) of a certain item can be modeled by the following exponential function
where, t is the number of years from today.
Substitute t=0 to find the current price.
Therefore the current price is $3000.
Substitute t=9 to find the price after 9 years from today.
Therefore the price after 9 years from today is $4054.
