1. A commercial air carrier determines that the maximum angle of depression of a plane descending to an airport is 11°. Determine horizontal distances from the airport at which aircraft must begin descending assuming cruising altitudes of: (a) 35,000’; (b) 41,000’; (c) 45,000’. State your answers in miles. 2. A road descending from near the peak of Sierra Blanca in New Mexico is 6.5 miles long and it has a total elevation drop of 2900 feet. What is the angle of depression of the road?

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
