Answer:

aₙ = 0.2(-0.3)⁽ⁿ⁻¹⁾

Step-by-step explanation:

The geometric sequence with the first term a, a common ratio r has the nth term given as

Tₙ = arⁿ⁻¹

where Tₙ is the nth term

From the given sequence

a = 0.2

r = -0.06/0.2

= -0.3

Hence the nth term

= 0.2 * -0.3ⁿ⁻¹

The right option is E

2) About how many students do not prefer non- fiction?
Mkey [24]

Answer:

about 465 students do not prefer non-fiction

Step-by-step explanation:

first I labeled each section on the pie the

the blue area looks like the smallest so that's most likely 60 students

then orange is 75 students

dark blue is the biggest so its 180 students

gray and yellow are the last ones left and gray is bigger than yellow so gray is 150

the number of students that prefer non-fiction is 100 so you add all the other number to get how many students don't prefer non-fiction=465

I hope this helps and makes sense ;D

Answer:

Slope of Function B = - Slope of Function A

Step-by-step explanation:

Function A

f(x) = - 2x + 1

This is in the form y = mx+b where m is the slope

The slope is -2


Function B

We have 2 points so we can calculate the slope

(0,-3) and (2,1)

m = (y2-y1)/(x2-x1)

   = (1--3)/(2-0)

   = (1+3)/(2-0)

    =4/2

2



Slope of A = -2       Slope B =2

The are opposites
