A car is traveling at a speed of 55 miles per hour.you want to write an algebraic expression to show how far the car will travel

goblinko [34]

Speed=Distance/Time
So Distance=Speed X Time
Distance=55T
Where 55 is the Car's speed and it is constant(won't change) and T is the time which is the changing variable.
you can plug time values to know the distance traveled!

The half-life of the given exponential function is of 346.57 years.

<h3>What is the half-life of an exponential function?</h3>

It is the value of t when A(t) = 0.5A(0).

In this problem, the equation is:

$A(t) = A(0)e^{-0.002t}$ .

In which t is measured in years.

Hence the half-life is found as follows:

$0.5A(0) = A(0)e^{-0.002t}$

$e^{-0.002t} = 0.5$

$\ln{e^{-0.002t}} = \ln{0.5}$

$0.002t = -\ln{0.5}$

$t = -\frac{\ln{0.5}}{0.002}$

t = 346.57 years.
