<h3>Answer: Choice A) 1/3</h3>

================================================

Work Shown:

x = preimage length = 12

y = image length = 4

z = scale factor

z = y/x

z = 4/12

z = (1*4)/(3*4)

z = 1/3

The scale factor is 1/3.

This means the image is 1/3 of the length of the preimage.

(8CQ) Find the sum of the geometric series. 20-10+5-5/2+...

Ivahew [28]

Answer:

b. $\frac{40}{3}$

Step-by-step explanation:

The given geometric series is;

$20-10+5-\frac{5}{2}+...$

The first term of this series is

$a_1=20$

The common ratio is

$r=\frac{-10}{20}=-\frac{1}{2}$

The sum to infinity of this series is

$S_{\infty}=\frac{a_1}{1-r}$

Substitute the given values to obtain;

$S_{\infty}=\frac{20}{1--\frac{1}{2}}$

This implies that;

$S_{\infty}=\frac{20}{\frac{3}{2}}$

$S_{\infty}=\frac{40}{3}$

Hi!

$|15x+2|=8\\\\\\15x+2=8\\15x=8-2\\15x=6 \ \ |:15\\\boxed{x_1=0,4}\\\\\\15x+2=-8\\15x=-8-2\\15x=-10 \ \ |:15\\\boxed{x_2=-\frac{2}{3}}$
