Answer: -3n+31
Step-by-step explanation:
1. 28-55=3
25-22=3
22-19=3
19-16=3
This means that n = -3 as we are subtracting
2. We then do the opposite, we take the first number and we add 3 instead of taking it away we get 31.
That is how you get your answer
-3n+31
Factors of 4: 2 and 2
y= (x+2)²
+√y or -√y = x+2
x= 2+√y , 2-√y
interchange variables
y= 2+√x , 2-√x
f ⁻¹(x) = 2 + √x, 2 - √x
The answer is Beryllium atom has a larger radius by 2 times.
Nitrogen atom: 5.6 × 10⁻¹¹ = 5.6 × 10⁻¹⁻¹⁰ = 5.6 × 10⁻¹ × 10⁻¹⁰ = 0.56 × 10⁻¹⁰
Beryllium atom: 1.12 × 10⁻¹⁰
Since 1.12 is bigger than 0.56, then the radius of beryllium atom is larger of the radius of nitrogen atom. Let's see by how many times:
1.12 × 10⁻¹⁰ : 0.56 × 10⁻¹⁰ = 1.12 : 0.56 = 2
