Step-by-step explanation:
<h3>Potential energy is the energy stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above ( or below ) the zero height.</h3><h3>- A raised weight </h3><h3>- Water behind a dam</h3><h3>- A car parked at the top of a hill</h3><h3>- A snow pack ( Potential avalanche )</h3><h3>- A yoyo before it is released</h3><h3>- River water at the top of a water hill</h3><h3>- A book on top of a table before it falls</h3><h3>- A child at the top of a slide</h3>

Step-by-step explanation:
Answer:
(A) 490ft.
(B) 2.8 miles
Step-by-step explanation:
Important points to note:
- The limestone layer is thought or assumed to slope downward in a straight line.
- 2 miles west of Seiling, the limestone layer was found at a depth of 220ft.
- 3 miles west of Seiling, the limestone layer was found at a depth of 270ft.
(A) What would you expect to be the depth of the limestone layer, 5 miles west of Seiling?
The expected depth of the limestone layer is:
2 miles + 3 miles = 5 miles
220ft + 270ft = 490ft
(B) Your budget will allow you drill a well that is 275ft deep. How far west of Seiling (in miles) can you go, to drill the well?
If 490ft ~ 5 miles
then 275ft ~ K miles
K = [275 x 5] / 490 = 2.80612245 miles
Rounding to 1 decimal place, the distance is 2.8 miles.
Answer:
30
Step-by-step explanation:
Step one, factor the denominators:
5x/(x-1)(x-6)-3(x+2)/(x+2)(x-6)
step two: make the denominators the same, the first fraction multiple (x+2), both top and bottom, the second one multiply (x-1), both top and bottom
simplify, I eventually get the answer (2x+3)/(x^2-7x+6)
