A skydiver free falls from a plane 200 feet above the ground. Which of the following equations could represent the height of the

skydiver as a function of time?
1. h(t) = -16t2 + 200t

2. h(t) = t2 + 199

3. h(t) = -16(t - 3) + 200

4. h(t) = -16t2 + 200

Answer:

Katie,

Once the skydiver reaches terminal velocity, then he will be falling with constant speed. The distance he falls in time t will then be d = (160 ft/s)·t. And his altitude above the ground (height h) will be his altitude when the parachute opened minus the distance he has fallen so we can write:

h = (3200 ft) - (160 ft/s)·t

As a point of interest, the time it will take him to fall all the way to the ground is t = (3200 ft)/(160 ft/s) = 20 s

A monument casts a 40 ft shadow. Adam is 6 ft tall and casts a 5 foot shadow. How tall is the monument
OLga [1]
The answer is 48 feet (D).

Explanation:

To solve this, you must think of the monument and its shadow and Adam and his shadow as a triangle, the person/object being the vertical leg, the shadows being the horizontal leg, and a line connecting them being the hypotenuse.  Also, we can assume that these triangles are similar.  First, we can set the scale to be 40/5 (the two shadows set a scale because the triangles are similar).  Then, we can put x/6 (the actual things are similar, and the scale was established to be building/measurement).  Next, we can set the two fractions equal to each other (40/5 = x/6) and solve.  We can cross multiply to get 5x = 40 * 6.  That goes to  5x = 240.  Finally, we can divide by five on each side to get x = 48 feet (D).

Gemiola [76]

Answer:

Owner-operators may take in over $260,000 in gross revenue, but once you deduct expenses, maintenance and all of the costs that go along with running a truck, many don’t earn much more than experienced company drivers. It costs about $180,000 per year to run a commercial truck. Operating costs in the trucking industry are about $1.38 per mile.
