Answer:
Step-by-step explanation:
First, we can find the slope using the two given points.
Then, we can use the slope we just found and one of the given points to find the y-intercept.
And we can put our equation together.
Hope this helps!
This is an exponential function and can be expressed as:
f=ir^t, f=final amount, i=initial amount, r=common ratio or "rate", t=time common ratio is applied or "time".
In this case: i=35000, r=(100-3.5)/100=0.965, so the exponential decay function is:
f=35000(0.965)^t
You can graph this with any graphing calculator or even if you type in most browser bars "y=35000(0.965^x)"
But mathematically:
15000>35000(0.965)^t divide both sides by 35000
3/7>0.965^t take the natural log of both sides
ln(3/7)>t ln(0.965) dividing both sides by ln(0.965), and remembering to reverse inequality sign because of division/multiplication by a negative value
t>ln(3/7)/ln(0.965)
t>23.78
So the population will drop below 15000 during the 23rd year.
Rounded up, the answer is 395 centimeters sq.
You’d get 12 dollars minus 1.32 which is 10 dollars and 68 cents
