snow_tiger [21]

Answer:

<h3>The value C(t) of the car after  5  years is $12709.</h3>

Step-by-step explanation:

Given that Landon bought a new car for $16,000 and it depreciates 4.5% every year.

<h3>To find the value C(t) of the car after  5  years:</h3>

Initial value C(0)= $16,000

Depreciation rate is  r=\frac{4.5}{100}

<h3>∴ r=0.045</h3>

Period ,  t=5 years

C(t)=C(0)(1-r)^t

Substitute the values we get

C(5)=16000(1-0.045)^5

=16000(0.955)^5

=16000(0.7943)

∴ C(5)=12708.8

<h3>The value C(t) of the car after  5  years is  $ 12709</h3>

A circular running track is 1/4 of a mile long Elena runs this track completing each lap in 1/20 of an hour what is her speed
PSYCHO15rus [73]

Answer:

The speed is equal to 5\frac{mi}{h}

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x------> the distance in miles

y-----> the time in hours

s----> the speed in mph

so

s=\frac{x}{y}

In this problem we have

x=(1/4)\ mi

y=(1/20)\ h

substitute

s=\frac{(1/4)}{(1/20)}=20/4=5\frac{mi}{h}
