Oh. Ok. Sorry, I didn't check my previous question. Thank you!

Ok. Thank you both!

Oh, ok. Thanks!

The squiggly A was originally a radical sign, but I guess it got changed.

No. These two are both separate problems. The book asks to simplify each problem. And for the 2nd problem the index is a four.

Well for the first one, the answer s supposed to be 1ã6xy/2y^2. The second problem's answer is xy/3 times the cubed root of 6y

That's alright then. Thank you very much.

Oh. I understand. That makes a lot of sense. Thanks!!

So for this you would use the Pythagorean Theorm. The formula is a^2 + b^2 = c^2, where c is the hypotenuse of the triangle. So if you know that the ladder reaches the height of 12m, that would be the hypotenuse in the triangle. 5m would be one of the leg...

I really like the second one, but do you have any ideas to get rid of the first person?

That's perfect!!! Thank you so much!!

I have all that information, but I still don't understand how to do it. How would you find the constant. And what does the s^ -1 stand for?

Oh ok. That makes sense. Thank you!

So if I changed it to... The hero displayed gallantry when he saved the woman. Is that better?

So for a triangle, two sides have to be greater than the largest side. Therefore, if you have three sides 7, 15, and x, you could say that... a) x is the largest b) 15 is the largest. a) If x is the largest side then 7+15 has to be greater than x. 22 has...

So for any set of polynomials that are not in a radical, the domain will usually be all real?

Ok, that makes sense. Thank you!

I am doing a similar problem where f(x) and g(x) are both square root of x+5. To find the domain of f+g and all that would I find the domain of each function...[-5,infinity). And then what? How would I add each set up?

Ok. I get it. Thanks for your help.

Well for this problem what you would do is you would take each set of ordered pairs and substitute the x coordinate for x and the y coordinate for y. If for all 5 ordered pairs a function works, then that is your answer. For example take the first one. Wi...

So first what you want to do it two put the numbers in order from least to greatest. 1, 1, 2, 2, 3, 3, 4, 4, 4, 5, 5, 6, 7, 16 So to find the mode you want to see which number is listed the most. That would be 4. To find the median you want to find the mi...

So substitute one of the x values in x. For example, substitute -3 for x f(x)=-(-3)+4 f(x)=3+4 f(x)=7 Therefore one of the values for y is 7. Do that for the rest of the x values and you will get the answers. Hope this helps!

1. So you know that the slope intercept form is y=mx+b, right. And m is the slope. So in this case there is no straight out coefficient, but x is also equal to 1x. Therefore one is your slope. 2. So first bring -6 to the opposite side of the equation by a...

Yes, you are right. Use distribution and multiply each number in the parenthesis aka the "10x" and "-12" by -3. So it would be 10x(times -3) - 12(times -3) -30x - -36 -30x + 36 Thats your answer. Hope this helps! Serena, a 10th grade student

I know what I did wrong. Some reason I divided the moles of C10H8 by .0120 instead of .120, so my answer was 11 times the answer it should have been. Thank you very much!

Never mind, I figured out I needed to convert the moles to grams and then I would use the q = mc delta t.
