Which of the following is the rule for the geometric sequence 1, 3, 9, 27, . . .?

Serhud [2]

Answer:

$a(n) = 1 \times {3}^{n - 1}$

Step-by-step explanation:

We started at 1
And it seems that index after index it multiplies by 3
The formula for the geometric sequence defined implicitly is a(n) =a(1)r^(n-1)

$a(n) = a(1) {r}^{n - 1} \\ a(n) = 1 \times {3}^{n - 1}$

Find the slope of the line on the graph.

Rasek [7]

The slope should be -1/2, because the line goes down 1 unit and then right 2 units.

Also it would be <u>y = -1/2x+1</u> in <u>y=mx+b</u>.

PLEASE HELP!

Bumek [7]

Answer:Yes.

Step-by-step explanation: Substitute either of the those values and you should get the other.

For instance, substituting x = 1 got you y = 5. If you had substituted x = 1 and got a different y-value, then the coordinates would have been incorrect.

A hose fills a hot tub at a rate of 4.42 gallons per minute. How many hours will it take to fill a 294-gallon hot tub?

suter [353]

Answer:

1 hour and 7 minutes

Step-by-step explanation:

set up two equations: $\frac{4.42g}{1min}$ = $\frac{294}{ ? min}$
cross multiply: 4.42x =294
solve for x: 294 ÷ 4.42 = 66.52 or 67 minutes

The question is asking for hours rather than minutes so...

- 1 hour is 60 minutes

67 min - 60 min = 7 min

Therefore, it would take 1 hour and 7 minutes to fill a 294-gallon hot tub.
