Problem 6758

An economy is based on three sectors, agriculture, manufacturing, and energy. Production of a dollar's worth of agriculture requires inputs of $\$ 0.20$ from agriculture, $\$ 0.40$ from manufacturing, and $\$ 0.20$ from energy. Product a dollar's worth of manufacturing requires inputs of $\$ 0.30$ from agriculture, $\$ 0.20$ from manufacturing, and $\$ 0.20$ energy. Production of a dollar's worth of energy requires inputs of $\$ 0.20$ from agriculture, $\$ 0.30$ from manufacturi and $\$ 0.30$ from energy.
Find the output for each sector that is needed to satisfy a final demand of $\$ 39$ billion for agriculture, $\$ 48$ billion for manufacturing, and $\$ 76$ billion for energy.

A professor at a local university designed an experiment to see if someone could identify the color of a candy based on taste alone. Students were blindfolded and then given a red-colored or yellow-colored candy to chew. (Half the students were assigned to receive the red candy and half to receive the yellow candy. The students could not see what color candy they were given.) After chewing, the students were asked to guess the color of the candy based on the flavor. Of the 110 students who participated in the study, 93 correctly identified the color of the candy. The results are shown in the accompanying technology printout. Complete parts a through c below.

Enter here the derivative with respect to $t$ of the distance between you and your friend: $\sqrt{v^{2}+w^{2}}$ Note: the next part will be MUCH easier if you simplify your answer to this part as much as possible.
Being scientifically minded you ask yourself how does the speed of separation change with time. In other words, what is the second derivative of the distance between you and your friend?
0
Suppose that after your friend takes off (at time $t=0$ ) you linger for an hour to contemplate the spot on which he or she was standing. After that hour you drive off too (to the North). How fast is the distance between you and your friend increasing at time $t$ (greater than one hour)?
