Need an answer showing work thax!

tensa zangetsu [6.8K]

Answer:

Option (a) $\sum_{k=1}^{\infty} \dfrac{3}{k(k+1)}$

Step-by-step explanation:

The given expression is :

$\dfrac{3}{1{\cdot} 2}+\dfrac{3}{2{\cdot} 3}+\dfrac{3}{3{\cdot} 4}+\dfrac{3}{4{\cdot} 5}+....$

We need to rewrite the sum using sigma notation.

The numerator is 3 in all terms.

At denominator, in first term (1)(2), in second term (2)(3) and so on.

A general term for the denominator is k(k+1).

Sigma notation is :

$\sum_{k=1}^{\infty} \dfrac{3}{k(k+1)}$

Hence, the correct option is (A).

F(x)=9x³ - x² + 2; f(2)<br><br> f(2)=

Lady bird [3.3K]

$\underline{ \boxed{\huge \sf \green {Answer :}}}$

$\: \:$

Given Function :

$\: \:$

$\large \tt\: f ( x ) = 9x³ - x² + 2$

$\: \:$

Now , put x = 2 in given function :

$\: \:$

$\large \tt \: f ( 2 ) = 9(2)³ - (2)² + 2$

$\: \:$

$\large \tt \: f ( 2 ) = 9(8) - (4) + 2$

$\: \:$

$\large \tt \: f ( 2 ) = 72 - 4+ 2$

$\: \:$

$\large \tt \: f ( 2 ) = 68+ 2$

$\: \:$

$\color{pink} {\boxed{\large \tt \: f ( 2 ) =70 \: ✓} }$

$\: \:$

Hope Helps!
