Math question
so its been a long time and a lot of bongs since i was in my advanced algebra classes in high school. but now in im math of finance for my accounting degree. i ran into this problem on my test and couldn't figure out to get the answer (ended up getting it because it was multiple choice - plug it in until you get it right)


4.51 = 1.08^n

solve for n.

I wanna know how, not just the answer plz

Right now, they just seem like a bunch of pies.

Exponents

Did a quick search... maybe that will help?

Divide by the square root of n.

Question
4.51 = 1.08^n

Take ln of both sides

Ln ( 4.51 ) = ln ( 1.08 ) ^ n

Rearrange

Ln ( 4.51 ) = n * ln ( 1.08 )

Divide

Ln ( 4.51 ) / ln ( 1.08 ) = n

Minus the numbers

Ln ( 3.43 ) = n

log4.5/log1.08 = n

I have digged a driveway in the shape of a circular segment...51 feet long tangent chord, and 10 feet at the middle ordinate of the segment.

find the cubic yards of stone needed to fill this segment with #1 ( approx. 1 inch) stones to a depth of approx. 2 inches with no slope.

Exactly what I wrote... I use ln instead of log base 10

hang on a sec, ln3.43 =1.232560....etc

1.08^ 1.23256 etc does not equal 4.51

or did i do it wrong?

I don't understand your description of the measurements. Draw me a diagram

Area of a circle segment - Math Open Reference


after that it's a simple volume calculation.

A merchant mixed 10lb of cinnamon tea with 5lb of spice tea, The 15 pound mixture cost $40. A second mixture included 12 lb of the cinnamon tea and 8 lb of the spice tea. The 20 pound mixture costs $54. Find the cost per pound of the cinnamon tea and of the spice tea.

This is the shit i could live without. It doesn't matter really how many i do in homework, when the exam arrives, who knows what will happen.
