1. You have the quadratic equation <span>n^2−8n+16=25 and to solve it, you must apply the proccedure below:
</span><span>
n^2−8n+16=25
</span><span>n^2−8n+16-25=0
</span><span>n^2−8n-9=0

2. When you factorize </span> n^2−8n-9=0<span>, you obtain the following:

(n-9)(n+1)=0

3. Therefore the values of n1 and n2 are shown below:

n1=9
n2=-1</span>

What is the reciprical of 200 and 450

Bad White [126]

Answer:

Part a) $\frac{1}{200}$

Part b) $\frac{1}{450}$

Step-by-step explanation:

we know that

A reciprocal of a rational number $\frac{p}{q}$ is obtained by changing the numerator and denominator, so the numerator becomes the denominator and the denominator becomes the numerator obtaining $\frac{q}{p}$

Part a) we have

200

we know that

the given number can be expressed as $\frac{200}{1}$

so

changing the numerator and denominator

The reciprocal is equal to $\frac{1}{200}$

Part b) we have

450

we know that

the given number can be expressed as $\frac{450}{1}$

so

changing the numerator and denominator

The reciprocal is equal to $\frac{1}{450}$
