Rob cut a 15-foot wire into 8 equal pieces. about how long is each piece
Archy [21]
For this answer it is really going to depend on what you are rounding to. You need to start by dividing 15 by 8. This gives you 1.875 feet. If you are wanting your answer to the nearest hundreth of a foot your answer would be 1.88 feet.
If you are wanting your answer to the nearest tenth of a foot your answer would be 1.9 feet. And if you are wanting your answer to the nearest food your answer would be 2 feet.

5. Landon bought a new car for $16,000 and it depreciates 4.5% every year. Write a function that describes
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>
