Your question seems a bit incomplete, but for starters you can write

Expanding where necessary, recalling that

, you have

and you can stop there, or continue to rewrite in terms of the reciprocal functions,

Now, since

, the final form could also take

or
5.14- 3.89 = 1.25 1.25/ 0.25 =5 m=5 I think, you might want to check it :)
Answer and explanation:
A center chord in a circle is the diameter of that circle. Therefore a center chord of a circle is different from other chords that touch two points on the circle but not in the center of the circle. A diameter of a circle is the chord that runs the length of the center of the circle touching two points at the edge of the circle. A diameter is twice the radius of the circle. So if the diameter of the circle is 12cm then the radius of the circle is 6cm
Answer: If the plane descends at the rate of 0.2 km per minute and landed after 15 mins, that means the plane started at 3 km elevation when it started to descend (t=0). The table is then constructed using the intialn values.
