Answer:
Step-by-step explanation:
Use the info given in the exponential equation to find the value of b, the rate of decay.
where v(t) is the value of the car after a certain number of years, t, have gone by, a is the initial value, and b is the rate of decay. We have everything we need but b:
a = 20000
v(t) = 16000 after t = 1 year:
so
b = .8 Taken in context, this means that the car depreciates 20% each year. Now we can solve the problem being asked of us, which is to find the value of the car after t = 5 years:
which simplifies down a bit to
v(t) = 20000(.32768) so
v(t) = 6553.60, choice C.
Answer:
The sale for the line plot should be from 0 to 1 with tick marks at every 1/10
Step-by-step explanation:
Hope it helps :)
The change in altitude would be 1200ft.
Imagine ft per minute as m.
That would be 300m.
In this problem, it asks what the change in altitude would be after 4 minutes. That would be m = 4.
So if m = 4, that would be 300•4, which is 1200.
Answer:
You start at the Y Intercept of 2, then you go up 2 units, and to the left 3 units. You will then make a line.
Step-by-step explanation:
Since it is not a negative slope, it will point to the top right corner.
