Answer:

AX = 14

Step-by-step explanation:

The medians of a triangle intersect at its centroid.

The position of the centroid X from the vertex A is

AX = $\frac{2}{3}$ AL = $\frac{2}{3}$ × 21 = 14

A factory that manufactures basketballs spends $3 on each basketball that it produces.

Iteru [2.4K]

Answer:

C. Neither linear nor non linear

Step-by-step explanation:

The company spends $3 on each basketball it produces, which means if the company produces $b$ basketballs, then the amount $y$ it would have spent is

$y=3b$ .

Now, the rate of cost growth is the rate of change, or the derivative of the amount spent $y$ ; therefore,

$\dfrac{dy}{db} =\dfrac{d(3b)}{db} = 3 \dfrac{db}{db} =3$

which is a constant, which means the rate of cost growth is not increasing. Therefore, rate of cost growth at the factory is neither linear nor nonlinear.

Find a closed form for the generating function for each of these sequences. (assume a general form for the terms of the sequence

noname [10]

There really is no single "obvious" choice here...

Possibly the sequence is periodic, with seven copies of -1 followed by six copies of 0, or perhaps seven -1s and seven 0s. Or maybe seven -1s, followed by six 0s, then five 1s, and so on, but after a certain point it would seem we have to have negative copies of a number, which is meaningless.

Or maybe it's not periodic, and every seventh value in the sequence is incremented by 1? Who knows?

I'll go ahead and assume the latter case, that the sequence is not periodic, since that's technically somewhat easier to manage. We can assign the following rule to the $n$ -th term in the sequence:

$\{a_n\}=\{-1,\ldots,-1,0,\ldots,0,1,\ldots,1,2,\ldots,2,3,\ldots\}$
$\implies a_n=\left\lfloor\dfrac n7\right\rfloor-1$

for $n\ge0$ .

So the generating function for this sequence might be

$G(a_n;x)=\displaystyle\sum_{n\ge0}\left(\left\lfloor\frac n7\right\rfloor-1\right)x^n$

As to what is meant by "closed form", I'm not sure. Would this answer be acceptable? Or do you need to find a possibly more tractable form for the coefficient not in terms of the floor function?
