Using an exponential function, it is found that it takes 5.42 years for the car to halve in value.
<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.
In this problem, the car depreciates 12% a year in value, hence r = 0.12 and the equation is given by:
.
It halves in value at t years, for which A(t) = 0.5A(0), hence:
t = 5.42.
It takes 5.42 years for the car to halve in value.

Answer:
1
Step-by-step explanation:
sin x = ½
x = π/6 = 30°
then
cos (x -π/6) = cos 0° = 1
Answer:
False
Step-by-step explanation:
The given statement is false. The histograms or bar charts are used when one is given discrete data for a certain value or the interval of a certain range but for the continuous data plotting, we need continuous frequency curves line graphs. Since the ALT levels fall on a continuum, representing them on a bar chart will not make any sense. they should be plotted on some continuous curve distribution lines like smoot line graphs (curves).
