A small resort is situated on an island that lies exactly 5 miles from P, the nearest point to the island along a perfectly straight shoreline. 10 miles down the shoreline from P is the closest source of fresh water. If it costs 1.8 times as much money to lay pipe in the water as it does on land, how far down the shoreline from P should the pipe from the island reach land in order to minimize the total construction costs?

The point P( 0.5 , 10 ) lies on the curve y = 5 / x . Let Q be the point (x, 5 / x ) . a.) Find the slope of the secant line PQ for the following values of x. If x= 0.6, the slope of PQ is: If x= 0.51, the slope of PQ is: If x= 0.4, the slope of PQ is: If x= 0.49, the slope of PQ is: b.) Based on the above results, guess the slope of the tangent line to the curve at P(0.5 , 10 ).

The gypsy moth is a serious threat to oak and aspen trees. A state agriculture department places traps throughout the state to detect the moths. When traps are checked periodically, the mean number of moths trapped is only 0.5, but some traps have several moths. The distribution of moth counts is discrete and strongly skewed, with standard deviation 0.7.What is the mean (±0.1) of the average number of moths x¯ in 40 traps? And the standard deviation? (±0.001) Use the central limit theorem to find the probability (±0.01) that the average number of moths in 40 traps is greater than 0.4:

The gravitational force, F, between an object and the Earth is inversely proportional to the square of the distance from the object and the center of the Earth. If an astronaut weighs 186 pounds on the surface of the Earth, what will this astronaut weigh 4050 miles above the Earth? Assume that the radius of the Earth is 4000 miles.
