3⁹ is the same as doing:

3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3

What I would do it is narrow it down piece by piece. 

3 * 3 * 3 = 27. Do that 3 times, now you are left with:

27 * 27 * 27

27 * 27 or 27² = 729.

That leaves you with:

729 * 27

You can multiply by hand or use a calculator to get your answer of 19683.

To check your answer, plug 3⁹ into a calculator. Your answer should match this.

The altitude of an airplane is decreasing at a rate of 42 ft per second what is the change in altitude of the airplane over a. O
bearhunter [10]

Answer:

Over a 22 seconds, the altitude will be: 924 feet

Step-by-step explanation:

  • Let 'x' be the time in seconds
  • Let 'y' be the altitude

As the altitude of an airplane is decreasing at a rate of 42 ft per second.

Thus, the expression to find the altitude at x seconds is:

y = 42x

so at x = 1 sec, y = 42 feet

Now, putting x = 22 seconds to determine the altitude at 22 seconds

y = 42x

  = 42(22)

  = 924 feet

Thus, over a 22 seconds, the altitude will be: 924 feet

PLS ANSWER QUICKLY!!! 20 POINTS!!! Select the correct answer. Jim's sock drawer has two pairs of black socks, three pairs of whi
ehidna [41]

Answer: B. 11/13

Step-by-step explanation:

So he starts out with 16, and picks out 3 of those 13. This means that he now has 13 socks in total in the drawer, so therefore, the answer could only be A or B. However, what makes it B, is that if he doesn't put them back, the only way he wouldn't get a full pair is with the green pair. That is where the 11/13 comes in, as two of the socks are green, making it not a full pair. But since he has 3 more black socks, 5 more white socks, and 3 more grey socks, when you add those together you get 11

5+3+3=11

Hope I helped!
