Which pairs of points would result in a line with a rate of change of 2:1? Select all that apply.

Helen [10]

Answer:

Options A, C, D are true.

Step-by-step explanation:

We have to choose the pair of points from that given in the attached file which will result in a line with a rate of change i.e. slope of 2:1 i.e. 2.

A. The points are (-4,-11) and (-2,-7).

Then the slope of the joining line is $\frac{-7-(-11)}{-2-(-4)} =2$

B. The points are (5,6) and (-5,12).

Then the slope of the joining line is $\frac{12-6}{-5-5} =-\frac{3}{5}$

C. The points are (0,-3) and (-4,-11).

Then the slope of the joining line is $\frac{-11-(-3)}{-4-0} =2$

D. The points are (0,-3) and (5,7).

Then the slope of the joining line is $\frac{7-(-3)}{5-0} =2$

Therefore, options A, C, D are true. (Answer)

Answer:

0.25 Converges

Step-by-step explanation:

First, we need to expand our series so that we get the following:

$\sum _{n=1}^{\infty \:}\frac{n}{4^n}+\frac{1}{4^{n+1}}$

We can then use the series ratio test on each term. (L < 1 = absolutely convergent)

$\sum _{n=1}^{\infty \:}\frac{n}{4^n}$

$\lim_{n \to \infty} \frac{n}{4^{n}\\}$ =

⇒ converges

$\sum _{n=1}^{\infty \:}\frac{1}{4^n^+1}$

$\lim_{n \to \infty} \frac{n}{4^{n}^+1\\}$

⇒ converges

converges + converges

= converges

Light travels about 180 million kilometers in 10 minutes. How far does it travel in one minute? How far does it travel in one se

astraxan [27]

Answer:

18 million kilometers in one min. and 0.3 million kilometers in one second

Step-by-step explanation:

so the one min. is easy because all you have to do is take 180 and divide it by 10 and you get 18 million kilometers in one min. and then you would take 18 and divide it by 60 and you would get 0.3 million kilometers in one second
