Answer:
Option C) -cosu is correct
Therefore the simplified expression is ![cos(u+\pi)=-cosu](https://tex.z-dn.net/?f=cos%28u%2B%5Cpi%29%3D-cosu)
Step-by-step explanation:
Given expression is ![cos(u+\pi)](https://tex.z-dn.net/?f=cos%28u%2B%5Cpi%29)
To find the value of the given expression :
By using the formula ![cos(A+B)=cosAcosB-sinAsinB](https://tex.z-dn.net/?f=cos%28A%2BB%29%3DcosAcosB-sinAsinB)
Substitute A=u and
in the above formula we get
![cos(u+\pi)=cosucos\pi-sinusin\pi](https://tex.z-dn.net/?f=cos%28u%2B%5Cpi%29%3Dcosucos%5Cpi-sinusin%5Cpi)
( here
and
)
![=-cosu-0](https://tex.z-dn.net/?f=%3D-cosu-0)
![=-cosu](https://tex.z-dn.net/?f=%3D-cosu)
![cos(u+\pi)=-cosu](https://tex.z-dn.net/?f=cos%28u%2B%5Cpi%29%3D-cosu)
Therefore option C) -cosu is correct
Therefore the simplified expression is ![cos(u+\pi)=-cosu](https://tex.z-dn.net/?f=cos%28u%2B%5Cpi%29%3D-cosu)

Answer: 29.1
Step-by-step explanation: You would multiply 15$ by .94 which is the same as 94% and get 14.1. You would then add the 14.1 to the 15$ and get 29.1$.
