2 (n-3) = 4n+1 What is n

Mathematics
1 answer:
dybincka [34]4 years ago
5 0

Answer:

-7

Step-by-step explanation:

distribute the 2 throughout the parenthesis. You should get 2n-6 on the left side of the equation. Then subtract 2n on both sides leaving you with -6=n+1. Finally, subtract -1 from both sides. n=-7

Hope this helps :)

Nahee is running around the circular track with equation x2+y2=10000 at a speed of 2.9 meters per second. She starts at the poin
Nana76 [90]

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 = 2 \times \frac{22}{7}\times 100 = 628.57 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 = \frac{360}{628.57}\times 62 = 35.512^{\circ}

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)
