HELP PLZ! THIS IS TIMED.

IgorC [24]

Answer:

$b_n=\dfrac{2}{3}\cdot (9)^{n-1}$

Step-by-step explanation:

Given the geometric sequence

$a_1=\dfrac{2}{3}\\ \\a_n=3a_{n-1},$

then

$a_1=\dfrac{2}{3}\\ \\a_2=3a_1=3\cdot \dfrac{2}{3}=2\\ \\a_3=3a_2=3\cdot 2=6\\ \\a_4=3a_3=3\cdot 6=18\\ \\a_5=3a_4=3\cdot 18=54\\ \\...$

Hence,

$b_1=a_1=\dfrac{2}{3}\\ \\b_2=a_3=6=\dfrac{2}{3}\cdot 9\\ \\b_3=a_5=54=\dfrac{2}{3}\cdot 9^2\\ \\...$

Thus, the explicit formula is

$b_n=\dfrac{2}{3}\cdot (9)^{n-1}$

Montega and Luisa are rewritting the scale 1 inch=2 feet in a:b form. who is right?

vitfil [10]

The correct representation of the scale is 1 inch:2 feet

<h3>What are scale ratios?</h3>

Scale ratios are used to show the relationship between quantities of different measurements

The scale is given as:

1 inch = 2 feet

Represent the above scale, as ratio

$Ratio = 1\ inch:2\ feet$

Hence, the correct representation of the scale is 1 inch:2 feet

Which equation represents a line which is parallel to the line y=-7/5x-1

d1i1m1o1n [39]

Answer:

Well, i dont see a set of points, so i am assuming that you just want the equation.

Since the equation is needed to be parallel to the line y = -7/5x-1, you keep the slope, so the equation would be y = -7/5x + b
