The answer is A !!!!!!!!

the two segments AD and AB are equal therefore if you make the two equal to each other you will get the answer:

<span>x^2+2=11 then you subtract two to put x squared on the side by itself
</span>then you have <span>x^2=9
then all you have to do is take the square root of 9 and </span><span>x^2 and you get x=3
thefore the answer is A</span>

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).

Answer:

B

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

here [ a, b ] = [ 2, 4 ]

f(b) = f(4) = 16 ← from graph

f(a) = f(2) = 4 ← from graph

average rate of change = $\frac{16-4}{4-2}$ = $\frac{12}{2}$ = 6
