Answer:
Car B by 20km/hr
Step-by-step explanation:
well, we first calculate the speeds of both cars. there is an allocated dot along the 6 hour mark for the line graph of both cars. hence, using a time of 6 hours, we use their respective distances to produce an answer. car a has travelled 360 km while car v has travelled 480 km.
hence:
speed of car b = 480/6 = 80
speed of car a = 360/6 = 60
Answer:
$31.50
Step-by-step explanation:
30% of 45 is 13.5
45-13.5=31.5
Using an exponential function, it is found that the value of the car after 5 years will be of $8,527.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
For this problem, the initial cost and the decay rate are given as follows:
A(0) = 23000, r = 0.18.
Hence the value of the boat after t years is given as follows:



The value after 5 years will be of:

The value of the car after 5 years will be of $8,527.
