is it 46 ??? because i did the work and don't feel like explaining
This means that it's 12 times f, then add that by 24. This f is a variable. It could be any number. First, try to find out what f equals. Then use that to find the answer.
30 = 5(m) + 7(n)
5(a) + 30 = 7(a)
(a) is the number of visits!
15 = (a)
5(15) = 75 + 30 = 7(15) = $105
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.
