How do you factor 4s2-9?
4s2 - 9 can be expressed by using the identity: a2 - b2 = (a-b)(a+b) Therefore, 4s2 - 9 = (2s)2 - 32 = (2s-3)(2s+3)
How you write x to the power of -2?
1/x2 or x-2
How you write 10 to the power of -2?
12
How do you write 2 x 10 to the 2nd power?
2 x 102 or 200
How to write a to the power 2 in Microsoft Word?
Highlight the 2 and change the font to superscript.
Write the electron configuration diagram that shows the transfer of electrons that takes place to form the compound sodium fluoride and include the electron configuration of the ions formed?
Na(1s^2 2s^2 2p66 3s^1) + F(1s^2 2s^2 2s^5) ----> NA+(1s^2 2s^2 2p^6) + F-(1s^2 2s^2 2p^6) Don't you love E20-20?
What power was used if it took 2s?
If work or energy was exerted or transferred in 2 seconds,then the power was(1/2) x (the number of joules of work or energy) watts.
If p equals 2s plus 5 what is s in terms of p?
If p = 2s + 5, then s = (p-5)/2 or 1/2 (p-5) --- p = 2s +5 p-5 = 2s (p-5)/2 = s
How can you use 5 2s to equal 26?
You can use three 2s to make 26 as follows (2x2)! + 2 = 26 So you can simply make 26 with five 2s as (2x2!) + 2 - 2 + 2 = 26
How do you determine the equation for the perpendicular bisector of the straight line joining the points s 2s and 3s 8s?
A = (s, 2s), B = (3s, 8s) The midpoint of AB is C = [(s + 3s)/2, (2s + 8s)/2] = [4s/2, 10s/2] = (2s, 5s) Gradient of AB = (8s - 2s)/(3s - s) = 6s/2s = 3 Gradient of perpendicular to AB = -1/(slope AB) = -1/3 Now, line through C = (2s, 5s) with gradient -1/3 is y - 5s = -1/3*(x - 2s) = 1/3*(2s - x) or 3y - 15s = 2s - x or x + 3y = 17s
How can you use five 2s to get 42?
Not sure about five, but you can make 42 with 6 2s with this method: 2[(22)! - (2/2) - 2] = 42
The correct electron configuration for nitrogen is?
a. [He]2s(squared) 2p(cubed)1s^2 2s^2 2p^3
What does 2s-4 equal?
2s-4 equals 2(s-2). You can find the answer by factoring two out of both numbers.
How do you factor 4s2-9?
4s2 - 9 can be expressed by using the identity: a2 - b2 = (a-b)(a+b) Therefore, 4s2 - 9 = (2s)2 - 32 = (2s-3)(2s+3)
How do you write of a to the power of 2?
As a to the power of 2 is the same as a squared then how about this a2
How do you write 256 as a power?
2 to the power of 8.
What is the answer to 5s - 6 equals 2s?
5s - 6 = 2s, ie 5s - 2s = 6, ie 3s = 6, ie s = 2
