Answer: About 986 meters.

Step-by-step explanation: You can multiply by the unit conversion

.3085 m/1 /ft × 3235ft = 986.028

Or divide 3235/3.281 Same thing. Round to "about 986 meters."

Answer:

If you mean m as in miles, then approx 0.61 miles.

Step-by-step explanation:

There are 5280 feet in a mile, so divide 3235 by 5280.

\sum_{n=1}^{\infty } ((-1^n)/n)x^n<br><br> Find the interval of convergence.

Lorico [155]

Answer:

(-1,1).

Step-by-step explanation:

We need to calculate $\lim_{n \to \infty}\frac{| a_{n+1}|}{| a_{n}|} = \frac{1}{R}$ where R is the radius of convergence.

$\lim_{n \to \infty}\frac{\frac{|(-1)^{n+1}|}{|n+1|}}{\frac{|(-1)^{n}|}{|n|}}$

$\lim_{n \to \infty}\frac{\frac{1}{|n+1|}}{\frac{1}{|n|}}$

$\lim_{n \to \infty}\frac{|n|}{|n+1|}$

Applying LHopital rule we obtaing that the limit is 1. So $1=\frac{1}{R}$ then R = 1.

As the serie is the form $(x+0)^{n}$ we center the interval in 0. So the interval is (0-1,0+1) = (-1,1). We don't include the extrem values -1 and 1 because in those values the serie diverges.

What function is represented by the graph?

earnstyle [38]

Answer:

$\displaystyle f(x) = [\frac{3}{4}]^x + 5$

Explanation:

All you have to do is plug in some intervals into the function based off of the graph, to make sure your function is authentic.

* Anytime that $\displaystyle a < 1,$ the graph will be <em>falling from the left</em>.

The total length of the stage is 76 feet. An actor starts at point A then stops at point B before disappearing through the trap

Sidana [21]

Answer:

since the distance from the outside edges is 26 1/2 feet, divide that by 2 to get the distance from the center to the edge ( 26 1/2 / 2 = 13 1/4 feet)

the stage is 76 feet so divide that by 2 to find the center 76/2 = 38 feet

now subtract the 13 1/4 from 38

38 - 13 1/4 = 24 3/4 feet from the side of the stage to the edge of the trap door

a little easier way would be to subtract the 26 1/2 from 76 and then divide by 2

76-26 1/2 = 49 1/2 / 2 = 24 3/4

Step-by-step explanation:
