Please help! Will award brainliest. Simplify the expression -5+i/2i. Please show your work.
lorasvet [3.4K]

(-5+i)/2i

multiply by i/i

(-5+i) *i = -5i +i^2 = -5i -1

2i*i = 2i^2 = 2(-1) = -2

(-1-5i)/-2

1/2 +5/2 *i

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

With respect to the <em>parent</em> function y = cos x, we have these function according to the order of the graphs:

  1. cos x
  2. cos (1/2)x
  3. cos 4x
  4. cos 2x
  5. cos (1/4)x

<h3>How to find the functions corresponding to each graph based on the period of a function</h3>

Mathematically speaking, cosines are <em>periodic</em> functions and period (T) is the distance in the <em>horizontal</em> axis such that f(t + T) = f(t). The period of the <em>parent</em> <em>cosine</em> function is 2π. Period in <em>daughter</em> functions may vary by means of the following form:

y = cos Ax     (1)

Where:

  • x - Independent variable
  • y - Dependent variable
  • A - Period width

Please notice that <em>daughter</em> functions report periods <em>longer</em> than in the <em>parent</em> function for 0 < A < 1 and a <em>shorter</em> one for A > 1. In consequence, these functions appear in the following order:

  1. cos x
  2. cos (1/2)x
  3. cos 4x
  4. cos 2x
  5. cos (1/4)x

The ordered pair (, 4) is a solution to the equation y=5x-1.
Snezhnost [94]
So, if you’re only given the y coordinate in your problem, you would plug that back into your equation
y=5x-1 turns into
4=5x-1 and you can solve by
5=5x
1=x
so the ordered pair turns out to be
