Which expression is equivalent to 2^2×2/2^4

Mathematics
1 answer:
dusya [7]3 years ago
6 0
First step is to simplify the equation so that it makes our life easier! Since 2^2 is equivalent to 4, we can plug that into the equation. Then we can also simplify 2^4 to 16. Now it should look like this:

(4)(2)/16

Now we can solve. 4(2) = 8 so now we have 8/16. 8/16 simplifies to 1/8 when you divide the numerator and the denominator by 8. So there you go! Your final answer is 1/8! I really hope that helped you out, and happy holidays!

Answer:

  y = -1

Step-by-step explanation:

Sides marked with the same marking are congruent, so we have two equations:

  • 3x -y = 16
  • 2x +y = 9

Adding the equations gives ...

  5x = 25

  x = 5 . . . . . . divide by 5

Then the second equation tells us ...

  y = 9 -2x = 9 -2(5) = -1

The value of y is -1.

Someone h e l p me on this it is geometry
ladessa [460]

BC = 6 km

<u>/</u><u> </u> ACB = 34°

AC = ?

cos 34° = \frac{BC}{AC}

=> 0.829 = \frac{6}{AC}

=> AC = \frac{6}{0.829}

=> AC = 7.23763570567

=> AC = 7 km

=> AC = 10 km\:\:\:\:\:\:\:\: (nearest tenth)

\\

<h3>Answer : 10 km</h3>

In rectangular form, 6(cos120°, isin120°)
anastassius [24]

Answer:

  (-3, 3√3)

Step-by-step explanation:

Evaluate each of the coordinates. Keep or drop the "i" as your convention requires.

  6(cos(120°), i·sin(120°)) = (6·cos(120°), i·6·sin(120°)) = (6(-0.5), i·6·√3/2)

  = (-3, 3√3 i)

You may want the (x, y) coordinates written as (-3, 3√3).

___

In the complex plane, this is -3+i·3√3.
