Answer:
The coordinates are (58.1, - 81.4).
Step-by-step explanation:
The distance traveled by Nahee after 13 minutes at the rate of 2.9 m/sec along the arc of the circle with equation x² + y² = 100², will be (13 × 60 × 2.9) = 2262 m
Now, the perimeter of the circle is 2πr = m
Therefore, after traveling three full circles and a half-circle the remaining arc length will be [2262 - (628.57 × 3) - (628.57 ÷ 2)] = 62 m
Therefore, Nahee will finish his run in the fourth quadrant.
Now, the angle made by the arc length of 62 m at the center will be =
So, the angle made with positive x-axis will be (90° - 35.521°) = 54.488°
Now, the coordinates of the finishing point are (x,-y) = (rCos 54.488°, - rSin 54.488°) = (58.1, - 81.4) (Answer)
Given the scale is 1 cm to 25 km.
We have to find the length of the trail from centimeter to the nearest tenth of kilometer.
Let's take the length of the trail be x km.
The length of the trail given 7.2 cm. We will have to find the length in km.
We have to set it up as a proportion. So we can write the proportion as,
We have to cross multiply first. We will get,
So we have got the required length of the train in kilometer.
The actual length of the trail = 180km.
