Answer:
it will take 15 weeks the money he owns and the money he earns will be the aame
This sin graph doesn't have a phase shift and its vertical displacement (d) is zero, so you don't need to include it in the equation of y = asin[b(x-c)]+d.
Equivalent expressions are expressions that have the same value
The equivalent expression of
is ![-16+37i](https://tex.z-dn.net/?f=-16%2B37i)
The expression is given as:
![(4 +7i)(3 +4i)](https://tex.z-dn.net/?f=%284%20%2B7i%29%283%20%2B4i%29)
Expand the equation
![(4 +7i)(3 +4i) = 4(3 +4i) +7i(3 +4i)](https://tex.z-dn.net/?f=%284%20%2B7i%29%283%20%2B4i%29%20%3D%204%283%20%2B4i%29%20%2B7i%283%20%2B4i%29)
Distribute the equation, as follows:
![(4 +7i)(3 +4i) = 12 +16i +21i +28i^2](https://tex.z-dn.net/?f=%284%20%2B7i%29%283%20%2B4i%29%20%3D%2012%20%2B16i%20%2B21i%20%2B28i%5E2)
In complex numbers,
![i^2 = -1](https://tex.z-dn.net/?f=i%5E2%20%3D%20-1)
So, we have:
![(4 +7i)(3 +4i) = 12 +16i +21i +28(-1)](https://tex.z-dn.net/?f=%284%20%2B7i%29%283%20%2B4i%29%20%3D%2012%20%2B16i%20%2B21i%20%2B28%28-1%29)
Evaluate the product
![(4 +7i)(3 +4i) = 12 +16i +21i -28](https://tex.z-dn.net/?f=%284%20%2B7i%29%283%20%2B4i%29%20%3D%2012%20%2B16i%20%2B21i%20-28)
Combine like terms
![(4 +7i)(3 +4i) = 12-28+16i +21i](https://tex.z-dn.net/?f=%284%20%2B7i%29%283%20%2B4i%29%20%3D%2012-28%2B16i%20%2B21i)
Evaluate like terms
![(4 +7i)(3 +4i) = -16+37i](https://tex.z-dn.net/?f=%284%20%2B7i%29%283%20%2B4i%29%20%3D%20-16%2B37i)
Hence, the equivalent expression of
is ![-16+37i](https://tex.z-dn.net/?f=-16%2B37i)
