Ah, okay.
Please help on part iv, I’ve no idea where to start.
No problem!
I believe you are correct. It started because of a conflict between France and Britain concerning the Americas, if I'm not wrong, and later grew to span across the world.
Thank you for your response. I have solved (a), (b) and (c). Yes, there is no solution for g(x)=3.
I found out how to solve it! You can factor the right side of the equation and subtract that from both sides, then factor by grouping the left side of the equation, which gives x = -1, 0, and 1.
Oh, I completely forgot that quadratics have both increasing and decreasing intervals! Thank you!
Also I asked a different Algebra question yesterday(17/6) at around 9 pm and it would be great if someone could offer some ideas on how to solve that algebraically.
Thanks for the response. I also got the solutions of 0 and 1 just by guess and check but I have no idea how it works!
You could compare the colors of the butterfly in different stages of life to things in nature. Such as a butterfly with wings the color of marigolds.
To our knowledge, literally nothing existed before the Big Bang. The Big Bang is what created everything. Space was space; quite literally a void of nothingness. If you believe in God like I do, there could be a religious explanation but currently we lack
Images can't be sent here. A ruler and compasses should be enough for you. MathWareHouse has some tips on geometric constructions, perhaps you could look there.
Thanks a lot, oobleck and Reiny! I understand it now :)
I'm not sure what "1o" centimeters means. But here's the formula for the surface area of a pyramid: B + (1/2)(ps) where B=area of the base, p=perimeter of the base and s=slant height. Use the Pythagorean Theorem to find the slant height. For part b, you'll
2:3 = 2 parts: 3 parts This means that there is a total of 5 parts. Emma's money is equivalent to two parts, so that means that $20 is the amount for one part. Now that you have the money for one part, multiply that by five and you have your answer.
Oh never mind, I completely understand the solution now. Thank you so much! This question really stumped me.
Thank you! I understand everything up until this line: a_4/a_3 > a_3+1 = 37/16 > 3/2 Isn't a_4/a_3 = a_3+1?
Ah, that's a much more clever way than what I came up with... unfortunately my math isn't advanced enough for that :')
The square root of −3−4i cannot be simplified. The magnitude is the absolute value, or a number's distance from zero. Do it yourself, it's not too tricky, try searching up what magnitude is. I suppose you could rewrite the square root of the complex
Thank you. I'll get to work on that immiediately.
I clicked on this question because I do enjoy doing art myself. But the question you've sent is impossible for anyone other than yourself to answer. Try Googling some approaches on creating an art portfolio. It is only you that would know how to properly
There are 12 months in a year. Each month it decreases by 2%. This means 98% of the original price will be remaining at the end of the first month. So to get the price of the care after one month, it would be 20000*0.98=19600 Repeat the process I just did
It says that it must be a multiple of 3 and a multiple of 4, so list out the multiples of 3 and 4 going up to 12 and see where they overlap. This is the first step. I'm sure you can figure it out from there.
If she's filling up a sphere with sand, it means that we need to know what the volume of the sphere is. The formula for the volume of a sphere is: (4π)*((r^3)/3)) We know that the radius is 2, so we have: (4π)*((2^3)/3)) Now just simplify it.
This isn't quite algebra, but since this fits right in with my knowledge, I'll answer it. So base 2. If you don't know what that is, it's binary numbers - written only with 1 and 0. Binary numbers are usually specifically used for one general subject, a
We know what the value of x is: 15. So, just plug in the value of x. You can put it into a calculator and round. By the way, in case you don't know, to "plug in a value" means to substitute in the value.
By the way, that's a URL, but only copy the link after the "//"(I'm not allowed to post URLs).
I believe you are correct. However, I am no expert, so try this link: //mahargpress.com/wounded/additional-material/timeline-of-vietnamconflict/ Good luck!
Alternatively, you could multiply $30 by (7/12).
We know that the price for 12 cans is $30. So we can set up an equation. Let c equal the price of one can. 12c=30 Now solve the equation for c, and multiply the value of c by 7.
Oh, I've figured it out! Thanks for the help, but I've found another method.
Thank you for the response. Yes, I do think there might be a miscalculation. From running this through a calculator, I got y=1/(1-x). Another thing: I don't get how one could get ±(-1, 1/2, 2) as a solution through just inspection. Is there math behind
Thanks for the response! I still have a question though - what do you mean by picking any other values of x? Is there an equation that I'm supposed to solve?
Hi yesennia, Please include all the expressions in your question. No one will be able to answer if we aren't given the answer choices! ~Dog_Lover :)
Never mind, I found an answer. Thanks for the help though!
Thanks for the reply. I hadn't considered the idea of using perfect cubes. How would I use perfect cubes, though? I'm still confused.
Oh, I just found a new way to solve it. And wow, this is an old problem :') But you can just put x in the equation for everything between 1 and 16, then find the y values and add them up. Got me 45!
Hmm... I got 46. Though I do think 45 is correct; I must've had a miscalculation. Nice explanation, Overseer! :)
This seems to be simple algebra. C(x) is the total cost of the calculators, and the total cost is also $104,000. So now we have the equation 104,000=51x+2000. Subtract 2000 from both sides of the equation and divide by 51.
Think about which one shows a comparison between genders. That should be your answer.
Nevermind, sorry. Both are correct.
Your answer for a. is right, but b. is incorrect.
Finding a slope is difference in y over difference in x. So, just find the slopes of AB and CD. Slopes remain the same after translations, so think about why that is to answer Parts B and C. When you've finished, send your answers so someone else or I
Well, if you don't know what creative outlet Noah discovered, you clearly haven't read the book. Try reading and putting effort into your work.
Brainstorming is basically when you come up with a bunch of ideas, and clustering is combining similar ideas. So now all you have to do is think about how you could use each of these differently.
I haven't read the book or ever heard of it, but from what I can tell, 8 and 9 are wrong, and the rest seems to be correct.
You should search it up. Or even better, do it yourself. :)
Oh never mind, I have finished the problem.
I also almost solved (b), just one thing I don't get: what do we do once we have found the coordinates of A'?
Thanks, I solved (a).
