Answer:he will save 100 $
Step-by-step explanation:
You can tell that a line is parallel if the lines can go on forever without crossing or intersecting. A line is perpendicular when the lines intersect at a right angle. If the slopes are either equal or negative reciprocals, they cannot be parallel or perpendicular.
Hope this helps you!
The correct option is: B. ![25000=5000(1.043)^t](https://tex.z-dn.net/?f=25000%3D5000%281.043%29%5Et)
<u><em>Explanation</em></u>
<u>The general form of growth equation</u> is:
, where A = final amount, P = initial amount, r = growth rate in decimal form and t = time duration
Here, the speed of the rocket at the beginning was 5,000 kilometers per hour and at the end will be 25,000 kilometers per hour. The speed increases at a rate of 4.3% per minute.
That means, ![A= 25000 , P= 5000, r= 4.3\% = 0.043](https://tex.z-dn.net/?f=A%3D%2025000%20%2C%20P%3D%205000%2C%20r%3D%204.3%5C%25%20%3D%200.043)
Now <u>plugging these values into the above equation</u>, we will get......
![25000=5000(1+0.043)^t\\ \\ 25000=5000(1.043)^t](https://tex.z-dn.net/?f=25000%3D5000%281%2B0.043%29%5Et%5C%5C%20%5C%5C%2025000%3D5000%281.043%29%5Et)
So, the equation that could be used to determine the time for the speed of the rocket to reach 25,000 kilometers per hour will be: ![25000=5000(1.043)^t](https://tex.z-dn.net/?f=25000%3D5000%281.043%29%5Et)
