its sophisticated but answer is 3
Step-by-step explanation:
you have to dive deep into it and research
Answer: well if p= $1000 and t=6 and r-11 % then 6k+11=1000 then 11- 1000 is 6k=989 divide 6/ 164.83 i think
Step-by-step explanation:
Answer: - 5
Explanation:
1) Some information in the question is missing: the height of the roller coaster at the bottom of the drop.
2) Here is the complete question: "Across a horizontal distance of 25 feet, a roller coaster has a steep drop. The height of the roller coaster at the bottom of the drop is -125 feet, compared to its height at the top of the drop. What is the average amount that the roller coaster's height changes over each horizontal foot"
3) Now, you can calculate the average amount that the roller coaster's height changes over each horizontal foot, using this formula:
Average change = [change in height] / [change in horizontal]
4) Change in height = [final height - initial height] = - 125 feet
5) Change in horizontal distance = 25 feet
6) Answer: - 125 feet / 25 feet = - 5.
The negative sign means that the height decreased.
Step-by-step explanation: 15 + 13 + 2
Answer:
<h2>A.</h2>
Step-by-step explanation:
We know that the whole length of the circumference is
.
By given, we have
, and
by definition of central angle.
That means
![HJR=HJ+RJ\\\frac{9}{10} \pi = 81\° +RJ\\ 162\°-81\°=RJ\\RJ=81\°](https://tex.z-dn.net/?f=HJR%3DHJ%2BRJ%5C%5C%5Cfrac%7B9%7D%7B10%7D%20%5Cpi%20%3D%2081%5C%C2%B0%20%2BRJ%5C%5C%20162%5C%C2%B0-81%5C%C2%B0%3DRJ%5C%5CRJ%3D81%5C%C2%B0)
Also,
![RHJ=360\° - RJ=360\° - 81\° =279\°](https://tex.z-dn.net/?f=RHJ%3D360%5C%C2%B0%20-%20RJ%3D360%5C%C2%B0%20-%2081%5C%C2%B0%20%3D279%5C%C2%B0)
Therefore, the measure of the arc RHJ is 279° which is equivalen to choice A.
![\frac{31}{20}\pi = \frac{31}{20} \times 180\° = 279\°](https://tex.z-dn.net/?f=%5Cfrac%7B31%7D%7B20%7D%5Cpi%20%3D%20%5Cfrac%7B31%7D%7B20%7D%20%5Ctimes%20180%5C%C2%B0%20%3D%20279%5C%C2%B0)
