I think Minecraft is better.

Minecraft has a better visual effect and design than roblox.

x² - 100 = 0

(x + 10)(x - 10) = 0

x = 10 or -10

20th line first number = 19² + 1 = 362

20th line last number = 20^2 = 400

20th line = 362 , 363, 364, 365 , ....... , 400

6.8 * 40

= 68 * 4

= 272

\(16^x = 2\\ x\ln 16 = \ln 2\\ x =\dfrac{\ln 2}{\ln 16} = \dfrac{\ln 2}{\ln(2^4)}=\dfrac{\ln2}{4\ln 2}=\dfrac{1}{4}\)

Whoops what am I doing

I should do:

\(2x^2 + 5x - 12 = 0\\ x = \dfrac{-5 \pm \sqrt{5^2-4(2)(-12)}}{2(2)}\\ \;\;=\dfrac{-5\pm 11}{4}\\ x = \dfrac{3}{2}\text{ OR }-4\\ \therefore 2x^2 + 5x - 12 = (2x - 3)(x + 4)\)

2x² + 5x - 12

= 2 (x² + 5x/2 - 6)

= 2 (x² + 5x/2 + 25/8 - 73/8)

= 2(x + 5/4)² - 73/4

= (2x + 2.5)² - 73/4

= \((2x + \dfrac{5}{2}-\dfrac{1}{2}\sqrt{73})(2x+\dfrac{5}{2}+\dfrac{1}{2}\sqrt{73})\)

2/4 \(\div\) 3

= 1/2 x 1/3

= 1/6

N x 2 : 3 = 2 : 7

N x 2 : 3 x 3 x 7 = 2 : 7 x 3 x 7

N x 2 = 6

N = 3

Add them up!!

\(\text{Perimeter}\\ =\dfrac{3}{8} + \dfrac{1}{2}+\dfrac{3}{4}\\ =\dfrac{3}{8} + \dfrac{1\times 4}{2\times 4}+\dfrac{3\times 2}{4\times 2}\\ =\dfrac{3}{8} + \dfrac{4}{8}+\dfrac{6}{8}\\ =\dfrac{3+4+6}{8}\\ =\dfrac{13}{8}\\ =1 \dfrac{5}{8}\\ =1.625\)

Last 3 rows are just the same. Depends on which one do your teacher prefer you to use.

My definition:

The Pythagorean Theorem, also called Pythagoras's Theorem or Pythagoras Theorem, is the relations of lengths of the 3 sides of a right triangle. It says that the sum of the square of the lengths of the 2 legs is equal to the square of the hypotenuse.

Use properties of operations on the more complicated side, if it still not EXACTLY and OBVIOUSLY equivalent, use properties of operations on the other side. If the results are OBVIOUSLY the same (e.g. 10 = 10)<-- very obvious, then the expressions are equivalent. Vice Versa.

1. Dialating the triangle by a scale factor of 5 makes the base 5 times as long as before and the height 5 times as long as before. Therefore answer is 5 x 5 = 25. The coordinates are just useless. XD

2. SAS Theorem

3. You have the base length and the height of the pyramid and more actually XD, But you just need to use the base length and height.

Volume = \(\dfrac{1}{3}(\text{base length})^2\times \text{height}\)= \(\dfrac{1}{3}\cdot 16^2 \cdot 15\) = 1280 cubic ft

\(\dfrac{2}{3}x + 8 = 20\\ \dfrac{2}{3}x + 8 - 8 = 20 - 8\\ \dfrac{2}{3}x = 12\\ \dfrac{2}{3}x \times \dfrac{3}{2}=12\times\dfrac{3}{2}\\ x = 18\)

\(y = -3x - 6\\ -y = 3x + 6\\ 3x - y = 8\\ 3x + (3x + 6) = 8\\ 6x + 6 = 8\\ x +1 = \dfrac{4}{3}\\ x = \dfrac{1}{3}\\ y = -3(\dfrac{1}{3})-6 = -7\\ \therefore x = \dfrac{1}{3};y=-7\)

This is enough, if you did this for homework. Anyways I will provide more.

Cooker

remote control

Switches(I think switches counts as an electronic, it is a part of electronic though)

Doorbell

LED screens(lots of them in Hong Kong that makes you can't sleep well everyday. Crazy)

Power? Energy? IDK.

My opinion.

 There is a creature with higher intelligence controlling us.(Maybe not god, Studies have shown that God is only slightly possible but here we call it god first. Read P.S.) God knows when you die, how you die, so if you suicide, God knows because he planned all human's life. Even if you are lucky that you did not die from attempt to suicide, God still knows because he already planned it. So, commit suicide isn't immoral, he knows.

 To respond the question "Why is it our responsibilty to continue the human race?", I think that there is a kind of mysterious power to make us want to continue the human race while not knowing why. 

 "Are we being forced to live?" I think not. God has planned everything(Not god again, read P.S.) and he knows if you do not want to live and he will control you to suicide.

I think this opinion is so negative...... but I really think so.

P.S. Studies have shown that the probability of "We are just a kind of simulator" is about 100,000 times higher than the probability of "We are created by god".

Another P.S. I am 14, and I have been thinking about these kind of "philosophical" questions since last year

Answer:

Multiply them together:

\(1/7 \times 21\\ = 3\)

\(\lim_{n\rightarrow infinity}{{(\sqrt[n]{|{(-1)}^{n}*(1-(\frac{15}{n}))|})}^{n}}^{2}= \lim_{n\rightarrow infinity}{|{(-1)}^{n}*(1-(\frac{15}{n}))|}^{2}=(\lim_{n\rightarrow infinity}{|{(-1)}^{n}*(1-(\frac{15}{n}))|})^2=1^2=1.\)

Yes, the exact result gives f(2) = 4e - 3 ≈ 7.8, as illustrated in my graph.

Euler's approximate numerical method lags well behind the exact function.

It really depends on the whole question but yes it is possible.

Also there are two ways to talk about compounding periods.

Nominal and Effective.

Anyway ... if you want more info you probably need to give the scenario or question in full.

You make a a great maths detective Hectictar :)

But the function is 4/e*e^x-x-1 isnt it? isnt it f(2)=4e-3?
