6.I am stuck in a math problem (calculus related rates) and have been stuck for a while. (I’ve been working
working on it since Friday) As it is reading break I doubt that I can cnotact my teacher before it is due.
The question is as following:
A light shines from the top of a pole that is 20 meters high. A ball is falling 10 meters away from the pole, casting a shadow on a building that is 30 meters away. When the ball is 25 meters from the ground it is falling at a speed of 6 meters per second. How fast is the shadow moving?
side note: from left to right it goes lamp, falling ball, wall with shadow.
7.Hi, I have one question on my math homework that I can't seem to figure out. Please help me! Here
is Imagine that in the voting for a certain award, 7 points are awarded for first place, 4 points for second, 3 points for third, 2 points for fourth, and 1 point for fifth. Suppose there were five candidates (A, B, C, D, and E) and 47 voters. When the points were tallied, A had 155 points, B had 173 points, C had 170 points, and D had 154 points. Find how many points E had and give the ranking of the candidates. (Hint: Each of the 47 ballots hands out a fixed number of points. Figure out how many, and take it from there.)
