8. Here is the problem…..Determine the rational function R(x) has a graph that crosses the x-axis at -1, touches the x-axis at -4, has vertical asymptotes at x=-2 and x=3, and has one horizontal asymptote at y=-2……

Is this the answer? R(x)=(-2(x+1)(x+4))/(x+2)(x-3)

Six missiles are positioned at each of the six vertices of regular hexagon ABCDEF. Each side of ABCDEF is one mile in length. The missiles take off simultaneously, each one always heading directly toward the missile in front of it -- the missile starting at point A always heads toward the missile starting at point B, etc.

The missiles clearly follow a spiral pattern. Do the missiles simultaneously meet in the center, or do they spiral away from each other? If they meet in the center, how far does each missile travel?

Scientists assumed the fish was extinct because of fossil evidence. Why did the remains of this fish cease to generate fossils that would show that it did not disappear 80 million years ago? If it is alive today, why don't we have 60, 50, 40 million year old fossils?

1. If m^15 = 48 over y and m ^13 = 2 over 6y and m > 0, what is the value of m?

2. If 1 over 4 of an even positive # and 5 over 6 of the next larger even # have a sum of 32, what is the average of the 2 #'s?

I posted this question before and I got this answer: Just wondering if anyone could explain how to get the 91 over 3.

(1/4)(x)+(5/6)(x+2)=32

(13/12)x=91/3

x=28
x+2=30

Avg: 29

Thank you. I appreciate any steps.reasoning shown :].

If the percent chance of rain on a certain day is 30%, does that mean 30% of the time it should be raining, 30% of the forecast area will have rain, or something else? Another way to put it is, if the chance of rain is 100% does that mean it certainly will rain during the forecast period and if it is less than 100% does that mean it may or may not rain?
