2. David determines that 3 sqrt 2 cis(7pi/4) = -3+3i. When he considers the graphical representation of these numbers, he knows
fiasKO [112]

The correct rectangular equivalence of 3sqrt(2)·cis(7pi/4 ) is:

3sqrt(2)·cos( 7pi/4 ) + i·sqrt(2)·sin( 7pi/4 )  =  3 - 3i.

<h3>Where did David go wrong?</h3>

David mistakenly interchanged the Sin function and the Cos function when he was calculating the problem.

Hence the correct rectangular equivalence is:

3sqrt(2)·cos( 7pi/4 ) + i·sqrt(2)·sin( 7pi/4 )  =  3 - 3i.

<h3>What is rectangular equivalence?</h3>

An equation is rectangular in form when it is comprised of Variables like X and Y and can be represented on a Cartesian Plane.

What is the solution set for the inequality 4 - 5g &gt; 39?
katrin [286]

The solution set for the given inequality is g > -7

<u>Given the following inequality:</u>

  • 4 - 5g > 39

<h3>What is an inequality?</h3>

An inequality can be defined as a mathematical relation that is typically used to compare two (2) integers or variables in an equation by illustrating any of the following:

  • Greater than (>).
  • Less than (<).
  • Greater than or equal to the other (≥).
  • Less than or equal to the other (≤).

Simplifying the inequality, we have:

4 - 5g > 39\\\\5g > 4-39\\\\5g > -35\\\\g > -7
