- x=60
Answer:
720
Step-by-step explanation:
50/8=6.25
4,500/6.25=720
If your final is worth 15% of your grade and you have an 85 you need to score 118.33%. If you have an 85 and the final is worth 20% you need a 110%. If you have an 86 and the final is worth 15% you need 112.67%. If you have an 86% and the final is worth 20% you need a 106%. Good luck
z= r(cosθ+i sinθ) is the required polar form where, r = √41 and θ =π-
Step-by-step explanation:
Given,
-4+5i is a complex number.
To find the polar form.
Formula
z=x+iy
r² = mod of (x²+y²)
θ =
So, the polar form will be z=r(cosθ+i sinθ)
Now,
r² =(-4)²+5² = 41
or, r = √41
θ =π- [ since the point is in second quadrant]
Hence,
z= r(cosθ+i sinθ) is the required polar form where, r = √41 and θ =π-
