‼️PLEASE HELP‼️ Rosita is writing an explicit function for the geometric sequence:
80, 40, 20, 10,...
She comes up with t(n) = 160(1/2)^n
What domain should Rosita use for T so it generates the sequence?
Choose 1 answer
A: n ≥ 0 where n is an integer
B: n ≥ 0 where n is any number
C: n ≥ 1 where n is an integer
D: n ≥ 1 where n is any number

C- where n (greater than or equal to ) 1

Step-by-step explanation:

C- where n (greater than or equal to ) 1

Because in that sequence 0 doesn't make sense since 160 * 1/2 = 80 ^ 0 = 1. Doesn't make sense since there's no "1" in that sequence.

It's not "any number" because It can't be negative nor a decimal.

So, C.

:) hope this helps

The answer is C

Step-by-step explanation:

(I had the same Khan Academy question)

50=33x+22

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
