What's the test.

Would you like me to jump through some burning hoops for you ??

We are very obliging and patient here. :///  :)

sin(98.7654321) = 0.98832050156

x times -3 = -3x

Why does -2-5=-7 ?

because if you go down 2 steps and then you go down another 5 steps then you will have gone DOWN 7 steps altogether :)

15x² - 108x + 108

This is what I would do.

First take out common factors I mean take out the 3

\(=3(5x^2-36x+36)\)

Now I want two numbers that multiply to be 5*36=180

Since the multiple of 5 and 36 is positive the two numbers must both be positive OR both be negative.

The numbers need to add to -36 (the middle one) so they must both be negative.

Here I do use a bit of trial and error

5*36=5*2*3*2*3 = 5*6*6 = 30*6    bingo   the numbers are -30 and -6

-30*-6=180

-30+-6=-36

\(=3(5x-30x-6x+36)\)

Anyway, I hope that helps ;)

Another way to do it is to utilize the quadratic formula from that you can just gives the final factors not the break down of it.

\(\)

Do you mean quotient?   That means divide.

the quotient of 6 and 2 is 3

You cannot graph it as it because there is no y

logx143=0.96

\(log_x143=0.96\\ \frac{log143}{logx}=0.96\\ logx=log(143)/0.96\\ 10^{logx}=10^{log(143)/0.96}\\ x=10^{log(143)/0.96}\\\)

10^(log(143)/0.96) = 175.84972994163184

\(x\approx 175.84972994163184\)

check

log(143,175.84972994163184) = 0.9599999999999999

you are not goint to get any closer than that :)

Come on rarinstraw, we are not here to do all your homework for you.    

Try them with some numbers ans see what happens. 59 looks pretty easy.

63 is easy

If you look at the formulary on this site the log rules are there.

It depends on which bit is confusing you.

If you are confused about which is opp and which is adj maybe this will help. :)

It is a bit boring a guess but he explains fairly well.  :)

If the sales tax in your city is 7.9%,and an item costs $22 before tax,how much tax would you pay on that item.What would be your total price including tax?

Find 7.9% of $22 and then add it to $22

percent means divide by 100

so that is 

7.9 divided by 100 times 22.        Round the answer to the neares cent.  That is the tax

now add it to the pre tax price to get the sale price :)
