The value of a boat after t years is represented by the function f(t)=11,200(0.93)t
2 answers:
Answer: The initial value of the boat is $11,200.
Step-by-step explanation:
An exponential function is represented by
, where A is the initial amount , b is the rate of increase or decrease and t is the time period.
The given function is an exponential function which gives the value of a boat after t years
If we put t=0 {initial time}
Thus, The initial value of the boat is $11,200.

Answer:
Pan is closest to Paris when she gets to Florence when she is 35 miles away
Step-by-step explanation:
With Paris at (0,0), Rome is 40miles west which is on the negative x axis.
Florence is 35 miles closer (east to Paris) so we have -45 + 35 = -10
and 55 mikes north of Rome which is on the positive y-axis. So Florence is at point (-10,55)
The distance between the two points Florence and Paris is √(x2 - x1)^2 + (y2 - y1)^2
x1 = 0, y1 = 0
x2 = -10, y2 = 55
So we have
√(-10-0)^2 + (55-0)^2
= √(-10)^2 + (55)^2
= √ 100 + 3025
= √3125
= 55.9 mikes from Paris
