5)Suppose that the function P = 13+45ln x represents the percentage of inbound e-mail in the U.S. that is considered spam, where x is the number of years after 2000.

Carry all calculations to six decimals on each intermediate step when necessary.

a)Use this model to approximate the percentage of spam in the year 2003.

b)Use this model to approximate the year that the percent of spam will reach 95% provided that law enforcement regarding spammers does not change.

When my grandmother was still alive, my sister and I would go over to her house and spend the nights on weekends. The freaky thing was... her house was haunted...

It started years ago. My mother as a child noticed strange things happening to her. At night, someone would pull as her feet, yank the blankets off of her. My grandmother paid no attention to my mothers wild stories until one night she saw a little boy looking through the window at her. He wasn't outside.. it was more like a reflection. When she turned around, no one was there.

As my grandmother's children grew up and moved out, my sister and I would go and spend the night. We each had our separate rooms but sometimes I would go into my sisters room and we would play dolls or something before we went to sleep. (Mind you, we were around ten and eleven at this time.) On these nights, I would stay in my sisters room and we would talk before laying down for the night. But strangley, I could not sleep in that room with her. It was as though someone was telling me to leave. There would be three knocks on the wall - tap, tap, tap... At first we ignored them, taking them for an animal or a critter in the walls. But ten minutes or so surpassed and the knocking returned, this time more persistent - TAP, TAP, TAP... Once again, we ignored it and once again the knock came. Finally, I left the room and went to my own. Every night my sister and I tried to sleep in that same room together, the knocking would persist until one of us left.

Aside from the knocking, another fear plagued my mind. I would have extreme nightmares about the closet in that room. The nightmare was about a woman who would try to drag me into the closet to kill me. The strange part... she was invisible - I couldn't see her. How I know it is a woman, I don't know. When I have this dream, it is extremely difficult for me to wake up. When I finally do, it is very hard for me to breathe, hard for me to move. My mind is foggy and when I try to call out for someone, I cannot speak.

....To this day, I will not go into that bedroom. I haven't set foot into that room in over six years...

Recently, my aunt and uncle moved into my grandmothers old house. They lived there for a year before they started feeling any odd things. My uncle ignored them - he was used to them happening in this house due to the fact that he had grown up here after all! But my aunt was uncertain that she was even sane. She witnessed hazy appartitions flitting back and forth between rooms, objects moved, lights flickering. Eventually, she grew used to it. Then one night, as she was making dinner, she casually glanced up into the picture across the room and saw the thing in their home. She stared at the figure... a woman, just the same as in my nightmares.

Recently, I posted this story on another question someone had. They wrote to me claiming to be psychic and told me that a husband and wife with two children used to live in my grandmothers house. They told the story of how the man died in a tragic accident and the wife went insane with grief, shooting her two children before turning the gun on herself in the every closet that she escapes in my nightmares. If this is true, I do not know. But the strange fact remains... something still resides in my grandmothers house....

Ok, to clarify... The imaginary line between the north and south pole around which the world turns is, obviously, directly vertical (that is, at a right angle to its path of orbit around the Sun, if you visualise one of those solar system map things that you see in science textbooks etc).

What would happen if it was in fact 'vertical', so that when it orbited, all areas of the planet would be at a constant distance from the Sun at different times of year? Would seasons be eliminated? Would the equinox effect be eliminated? Would anything else happen?

Thanks very much if you can help me with this =)
