The exponential formula for this situtation will be given by:
f(x)=ae^(-bx)
where:
a=initial price
b=rate
x=time in years
hence the formula will be:
f(x)=28750e^(-0.12x)
thus the value of the car in 2018 will be:
x=2018-2012=6 years
thus
f(6)=28750e^(-0.12*6)
f(6)=$13,994.13

Answer: Angle x= 65
Step-by-step explanation: Find the other angles by subtracting the exterior angles with 180. 180-105= 75 180-140=40 The sum of the interior angles inn a traingle equal 180 when added together so, 75+40+65=180
Answer:
700%
Step-by-step explanation:
The price increased from $0.30 to $2.40. What is the rate of increase, in percentage?
We can use the formula shown below:
Where
New Price is 2.40 and the Old Price is 0.30
We substitute and calculate:
Hence,
Price increased 700%
