The domain of the function is given. Find the range.
Afina-wow [57]
The range is how much it spans in f(x), f(x) is a line, it has no max/min, so it's enough to substitute the least and greatest values of your domain:

f(-2) = -5, f(4)=7,

Range = [-5,7]

30 POINTS AND BRAINLIST FOR RIGHT ANSWER
alukav5142 [94]

Answer:

59°

Explanation:

If you add the angles 99° from angle C in the top shape and add 22° on the bottom shape it will give you 121°. When you get this subtract it from 180°

180°-121°= 59°

So, it's 58°

You can check by adding 180°+121°+59° = 180°

100 POINTS PLEASE HELP ME!!

3)

check the picture below.

bearing in mind that the point of tangency, the green one there, is always a right-angle, then we get that much for the distance AB.

since the satellite can emit a signal at a speed of 186,000 miles/second, how long will it be to cover AB?  well, it'll just be AB/186000, which is about 0.1381 seconds.

and how long will it be to cover the distance AE?  well, it'll just be AE/186000, which is about 0.11828 seconds.

of course is quicker to AE since it's closer, so the difference for both distances will be AB - AE, which is about 0.01984121052328095721 seconds.



4)

if the satellite makes a revolution, or 2π, in 24 hours, and we know the satallite is orbiting at 22000+4000 or 26000 miles from the center of the Earth, thus its circular orbit has a radius of 26000, how many miles is that?

well, Circumference of a circle is C = 2πr, if r = 26000, then C = 2π(26000), so on those 24 hours it has covered 52000π miles.

how fast must it travel then?    \bf \cfrac{52000\pi }{24}~\cfrac{miles}{hours}\qquad \approx \qquad 6806.78~\frac{miles}{hour}

now if you need the rate in miles/seconds, bear in mind that an hour has 60 minutes and each minute 60 seconds, thus and hour has 60*60 seconds or 3600, thus its speed in miles/seconds will be 52000π/3600.
