We have been given that Jackson purchases a new car for $48,000. The car's value can be modeled by the following exponential function: 
where y represents the car's value and t represents time in years. We are asked to find the decay rate as a percentage.
We know that an exponential decay function is in form 
, where,
y = Final value,
a = Initial value,
r = Decay rate in decimal form,
x = time.
Upon comparing our given function with standard decay function , we can see that 
.
Let us solve for r.
Let us convert 0.24 into percentage.
Therefore, the decay rate is 24%.
-1 is the opposite reciprical (perpendicular)
Find the square root of the area and yiull get the answer
Answer: 153.9 inches sq
Step-by-step explanation: The area of a circle is A= 3.14 times radius squared. Assuming we are finding area, we use this formula. The diameter is 14 so the radius is 7. Seven squared is 49, so we would do 3.14 times 49. This equals 153.86, then rounded is 153.9. I hope that I helped you out a bit!
