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 to the 9th power in standard form?
To write (2) to the (9)th power in standard form, you calculate (2^9), which equals (512). Thus, in standard form, it is simply written as (512).
How do you write 2 x 10 to the 2nd power?
2 x 102 or 200
How can you use five 2s to make 3?
To use five 2s to make 3, you can employ a mathematical operation like exponentiation. One way to achieve this is by arranging the 2s as follows: (2^2) - (2/2) = 3. This expression involves raising 2 to the power of 2 (which equals 4) and then subtracting the result of dividing 2 by 2 from it, resulting in 3.
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?
For the formation of sodium fluoride, sodium (Na) will transfer one electron to fluorine (F) to achieve a stable electron configuration. The electron configuration for sodium is [Ne] 3s^1, and for fluorine, it is [He] 2s^2 2p^5. After transfer, sodium forms the Na+ cation with an electron configuration of [Ne], and fluorine forms the F- anion with an electron configuration of [He] 2s^2 2p^6.
How are some ways to write two to the third power?
Two to the third power can be written in several ways, including (2^3), which represents the base 2 raised to the exponent 3. It can also be expressed as (2 \times 2 \times 2), showing the multiplication of three 2s. Additionally, the numerical result of (2^3) is 8, so it can simply be represented as 8.
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 make five 2s equal five?
Well, honey, if you want to make five 2s equal five, all you gotta do is write it as 2 + 2 + 2/2 = 5. Simple math, darling. Just divide one of those pesky 2s by 2 and voila, you've got yourself a nice little equation that adds up to 5.
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 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
Write electron configurations for each of the following ions?
An electron configuration refers to the distribution of electrons in orbitals. Since there are no ions given for this question, an electron configuration cannot be provided.
How do you make 9 from four 2s?
22/2 - 2
What elements completes the 2s sublevel?
The 2s sublevel can hold a maximum of 2 electrons.
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
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
