The number 4 is in the hundredths place in the decimal 0.045. The first number after the decimal is the tenths place (0), the second number after the decimal is the hundredths place (4), and the third number after the decimal is the thousandths place (5)....

Try making notecards with some of the most important information and vocabulary in the chapter. Use different colored index cards and highlight the words/phrases/equations that you have the most difficulty with. This is especially helpful if you are a vis...

Remeber the verbs for the verb "comprare" (to buy). Since "comprare" is an -are verb, recall the verb endings: Io: -o Tu: -i lui/lei/Lei: -a noi: -iamo voi: -ate loro: -ano Now, all you have to do is plug in the conjugated verb between the subject and the...

In order to conjugate(ex. comprare), take away the -are. So now you have compr-. Looking at the endings above, plug them into the stem of the verb so that the subject of the sentence matches the verb.

You have to use substitution for this problem. So, let u=(ln r). Then du=(1/r)dr. Now plug in u and du into the equation. This yields the integral of (sqrt(u)), which can also be written as the integral of u^(1-2). Now just integrate and plug (ln r) back...

I'm also taking this course and having trouble finding the information...what are the sources you used to answer these questions?

Don't see how you get 5? How do you square 4? 4*4 = 16 correct? So then how can R = 5? I don't get it...Thanks by the way for the graph!

I think I see what you are now talkin about! is this correct? D = sqrt ((x2-x1)2+ (y2-y1)2) -4- -4 = -8 1- -5 = 6 Half the distance between the two given points d = diameter = sqrt (82 + 62) =sqrt (64+36) = sqrt (100 = 10 Radius = 5 NOW i need to know how...

Would this be considered standard form? (4-0)2 + (-5- -2)2) = r^2 (4-0)2 + (-5- -2)2) = 5^2

What do you mean by "OK if you are teaching? I was just wondering?

16 years ago

I am going to try to. How can I graph this so I can see it?

16 years ago

This is what I came up with, but I am still having a hard time graphing it. Is this correct? Mid-point formula = (x1+x2)/2 (y1+y2/2 x = (4-4)/2 = 0 y = (-5 +1)/2 = -2 (0,-2) is the center??

16 years ago

I did it! The center is (0,-2) on the graph after tracing the circle. Now i need help with the length of the radius of the circle. (Note that this is a distance.) Give the exact answer? What do I do here please? Thanks!

Oh ok! Thanks again! You really know your stuff! Have a great weekend!

Thank you! I got many more of these to do, so just wanted to make sure my first one was correct! Thanks!

Simplify the expression. Assume all variables represent nonzero real numbers. -10b^5c^9/2b^5c^3

Thanks I found it.

Yes I will need the practice without a doubt! Now you say the The horizontal asymptote is y = 0 What about the the y-intercept and the vertical asymptote(s)?

16 years ago

I got 0 for the y-intercept why -3??? and The vertical asymptotes are x = -2, x = 2 ????

Where are you getting 2/3 from????

So static: 0.73 and kinetic: 0.57, thanks!

15 years ago

YES, that is correct!

it should be something that includes (x-1000) . it would be something like this : (x-1000) + x = 4400. im not sure. but its a close guess.
