Binomial Theorem, proof

IrinaVladis [17]

It follows from the definition of the binomial coefficient:

$\dbinom nr=\dfrac{n!}{r!(n-r)!}$

So we have

$(n+1)\dbinom nr=(n+1)\dfrac{n!}{r!(n-r)!}=(r+1)\dfrac{(n+1)!}{(r+1)!(n-r)!}$

That is, $(n+1)$ gets absorbed into the numerator's factorial, and we introduct $(r+1)$ into the denominator. Now, $(n+1)-(r+1)=n-r$ , so we get

$(n+1)\dbinom nr=(r+1)\dfrac{(n+1)!}{(r+1)!((n+1)-(r+1))!}=(r+1)\dbinom{n+1}{r+1}$

as required.

Answer:

45/28

Step-by-step explanation:

Hey There!

They want us to find the tangent of R

Remember in sohcahTOA

t - tangent

o - opposite

a - adjacent

meaning that

$tan = \frac{opposite}{adjacent}$

The opposite of angle r is 45

the adjacent of angle r is 28

so $tanR=\frac{45}{28}$
