Answer:
- The formula its
- After 5 years, the computer value its $ 1056
Explanation:
<h3>
Obtaining the formula</h3>
We wish to find a formula that
- Starts at 2816.
- Reach 0 at 8 years.
- Depreciates at a constant rate. m
We can cover all this requisites with a straight-line equation. (an straigh-line its the only curve that has a constant rate of change) :
,
where m its the slope of the line and b give the place where the line intercepts the <em>y</em> axis.
So, we can use this formula with the data from our problem. For the first condition:
So, b = $ 2816.
Now, for the second condition:
So, our formula, finally, its:
<h3>After 5 years</h3>
Now, we just use <em>t = 5 years</em> in our formula
True , because gravity is a force of nature. Matter (energy) does attract other matter
Answer:
B
Explanation:
The kinetic energy in an object is converted into potential energy. This makes the kinetic decrease, while the potential increases.
The car travels a distance of 200 kilometers for 1.31 × 10⁵ seconds.
We have:
The velocity of the car, v = 15.3 m/s
The distance traveled by car, d = 200 kilometers.
Now, let the time taken to travel the distance be t.
The formula for the speed of an object, when traveled a distance in a particular time, is given as:
Speed = distance / time
v = d / t
Now, d = 200 kilometers = 20 × 10⁴ m
Therefore,
t = d / v
t = 20 × 10⁴ m / 15.3
t = 131071.89 sec
t = 1.31 × 10⁵ sec
The car travel for a time 1.31 × 10⁵ sec.
