We are given the incomplete expression:

x^2 + b x

Now to complete the square, we need to add the square of the half of b, that is:

(b / 2)^2

b^2 / 4

Therefore the complete expression is:

Given:

Goryan [66]

Answer:

a.Converge

b.Diverge

Step-by-step explanation:

We are given that

$A_n=\frac{6n}{-4n+9}$

$\lim_{n\rightarrow \infty}A_n=\lim_{n\rightarrow \infty}\frac{6n}{-4n+9}=\frac{6n}{n(-4+\frac{9}{n})}$

$\lim_{n\rightarrow \infty}\frac{6}{-4+\frac{9}{n}}=\frac{6}{-4}=\frac{-3}{2}$

Because $\frac{9}{\infty}=0$

Hence, sequence An converges to $\frac{-3}{2}$ when n tends to infinity or - infinity.

$\sum_{n=1}^{\infty}An=\sum_{n=1}^{\infty}\frac{6n}{-4n+9}$ =diverges

Necessary condition for a series to converge :

$an\rightarrow 0$ when n tends to infinity .

But $A_n$ tends to $\frac{-3}{2}$ when n tends to infinity.

Therefore, given series is divergent.

Help! What is the answer?

fiasKO [112]

Answer: 22.4

Explanation:

The pieces of the chords multiply together to get the same result. This is from the intersecting chord theorem.

The first chord has pieces of 10 and x, which multiply to 10*x

This is equal to the other product found by multiplying the pieces 14 and 16 (from the other chord)

10*x = 14*16

10x = 224

x = 224/10 ... divide both sides by 10

x = 22.4
