Answer:
f(n) = 6* (3)^(n-1)
Step-by-step explanation:
We are multiplying by 3 each time
6*3 =18
18*3 = 54
So the common ratio is 3
The first term is 6
The formula for the geometric sequence is
an = a1 r^(n-1)
an = 6* (3)^(n-1)
f(n) = 6* (3)^(n-1)
Answer:
true
false

true
Step-by-step explanation:
80 × .25 = 20
80 × .10 = 8
80 × .40 = 32
80 × .20 = 16
80 × .5 = 4
.25 is equivalent to 25% and so on.
The answer is D cuz it cross the x
This would be easy for you if you know what the slope intercept form is.
y = mx + b this is the formula. M is where you put the slope and b is where the y-intercept goes. Now let's plug the numbers in.
The slope you said is -23 so that goes into the place of m. X is the variable. I'll give you an example. Say Mary put $100 into her bank account and every week she took 23 dollars. x would the number of weeks because it can change.
So back to plugging the numbers in. This is what it will look like when we put -23 in.
y = -23x + b. As we said above, b is the y-intercept. This is the point where the line on the graph crosses the vertical line, which is y. x is the horizontal line.
You said the y-intercept is -4 so the line crosses the vertical line at the point -4.
Plug this number into our formula,
y = -23x + -4.
There you go! We are finished making our slope intercept form equation.
I hope you understood, and good luck to you in the future.
