Answer:
GHD
OKG
4
BCF
Step-by-step explanation:
You can find it by the original equation
2=(1+r)^12
r=(2)^(1÷12)−1
R=0.0595*100=5.95%
3=(1+0.0595)^t
t=log(3)÷log(1.0595)
t=19 years
Answer:
900 square feet
Step-by-step explanation:
Step-by-step explanation:
the sum of the angles = 360
8x+2 + 2x + 14 + 3x -4 +5x + 5 = 360
18x +17 = 360
18x = 343
x = 19.1
angles are:
154.8
52.2 smallest (2x + 14)
53.3
105.5
As we know that any complex number written in the form ![a+ib](https://tex.z-dn.net/?f=%20a%2Bib%20)
can also be written as
in the complex plane.
Here the given complex number is ![-4i](https://tex.z-dn.net/?f=%20-4i%20)
which can be written as ![0-4i \ or \ (0,-4)](https://tex.z-dn.net/?f=%200-4i%20%20%5C%20or%20%5C%20%280%2C-4%29%20)
The polar representation is given as ![z=re^{i \theta}](https://tex.z-dn.net/?f=%20z%3Dre%5E%7Bi%20%5Ctheta%7D%20)
![r=\sqrt{4^2+0^2}=4\\ \\ \theta=tan^{-1 }\frac{-4}{0} =\infty\\ \\ \theta=\pi/2](https://tex.z-dn.net/?f=%20r%3D%5Csqrt%7B4%5E2%2B0%5E2%7D%3D4%5C%5C%20%5C%5C%20%5Ctheta%3Dtan%5E%7B-1%20%7D%5Cfrac%7B-4%7D%7B0%7D%20%3D%5Cinfty%5C%5C%20%5C%5C%20%5Ctheta%3D%5Cpi%2F2%20)
Hence the polar representation is
![z=4e^{i \frac{\pi }{2} }](https://tex.z-dn.net/?f=%20z%3D4e%5E%7Bi%20%5Cfrac%7B%5Cpi%20%7D%7B2%7D%20%7D%20)
