1) To concerve the contents of a 16-ounce bottle of tonic, a castaway adopts the following procedure. On the first day he drinks 1 oz. of the tonic and then refills the bottle with rain water. On the second day, he drinks 2 oz. of the mixture and then refills the bottl ewith more rain water. On the thrid day, he drinks 3 oz. of the mixture and again refills the bottle with more water. This procedure continues until the bottl eis empty. How many ounces of water did he drink when the bottle is completely empty?

2) This time the castaway has a smaller bottle that contains only five ounce of tonic. Using the same procedure as above, on which day does he drink the most tonic?

Decide if the algebraic manipulation is correct or incorrect. If incorrect, either correct it or
explain why the expression cannot be simplified.

e^x + e^-x = 10

I solved it graphically, but I have to know how to do it algebraically.

I have no idea how to attack this, I figured I'd take the natural log of all three to get an answer:

lne^x + lne^-x = 10
x - x = ln10
0 = ln10

That's obviously not right. How do I approach this? Thanks.

the distance, s m, fallen by a stone droped from a high point is proprtional to the square of the time, t seconds since it was droped. This show some values of t, t2 and s.

(a) use the known values to find the equation connecting s and t.

(b) copy the table and use the equation to fill in the missing values of s and t.



---please give your answers in full working out if you can---

I am having a very difficult time in my Algebra class learning how to calculate slope. My teacher rushes through the lecture, and leaves over half of the class in a stuper. Could someone, ANYONE, make an attempt to help me figure these problems out? And do you have any tips/suggestions that may make learning how to calculate slope any easier?

THANK YOU from the bottom of my heart to all who may answer and help me with this question!!!

Write an equation for each line passing through the given pair of points. Give the final answer in slope-intercept form.

1. (-1, -7) and (-8, -2)
2. (1/2, 3/2) and (-1/4, 5/4)

Write an equation of the line satisfying the given conditions. Give the final answer in slope-intercept form.

3. Parallel to 5x=2y+10; y intercept (0, 4)

Thanks again!!!

i need to use this..

in cm/ 1in = m. / 100cm. = meters

i need to use alot of numbers i just need to know how to work out this but i dont kno how.

the number i use is 39

so would i do this.

39 - 2.54cm / 1in = 99.06 m. / 100cm. = .9906m.

is that right or do i need to do it another way.

i need to be able to put that on a graph
