A negative exponent means the number of the exponent divide by the number. The the radius of beryllium atom is larger than the radius of a nitrogen atom by two times.
Given information-
The radius of a nitrogen atom is meters.
The radius of a beryllium atom is meters
<h3>Negative exponents</h3>
A negative exponent means the number of the exponent divide by the number.
As the radius of the nitrogen atom is meters. Convert it in the power of negative exponent of 10.
Let the radius of the nitrogen is mm. Thus,
Now the base of the exponents of both the atoms are same. As the radius of the nitrogen atom is meters and the radius of the beryllium atom is . Thus the radius of beryllium atom is larger.
To calculate how many times, the radius of beryllium atom should be divided by the radius of a nitrogen atom. Thus,
Thus the the radius of beryllium atom is larger than the radius of a nitrogen atom by two times.

Answer:
1.791
Step-by-step explanation:
Confidence interval for normal distributions can be stated in the formula
M±zσ where
- M is the <em>sample mean</em>, which is 1.14
- z is the corresponding <em>z-score for 99% confidence (one-tailed)</em>, which is 2.326
- σ is the <em>standard deviation </em>of the sample, which is 0.28
Thus, 99% lower confidence bound on the true Izod impact strength is
1.14+(2.326*0.28) = 1.791
X=y+m-z

Answer:
Step-by-step explanation:
Given
Solving (a): In vertex form
The vertex form of an equation is:
To do this, we make use of completing the square method.
We have:
------------------------------------------------------------------
Take the coefficient of x (i.e. -6)
Divide by 2; -6/2 = -3
Square it: (-3)^2 = 9
Add and subtract the result to the equation
------------------------------------------------------------------
Factorize
Factor out x - 3
Express as squares
Hence, the vertex form of is:
Solving (b): State the coordinates of the vertex.
In ; the vertex is: (h,k)
The vertex of will be
