I think it would take 15 days that’s what I got trying to figure out this question
        
             
        
        
        
Using cos addition formula:
use x for theta
cos(x+π/6)=cosx*cos(π/6)-sinx*sin(π/6)
sinx=1/4
cosx=√15/4
cos(π/6)=√3/2
sin(π/6)=1/2
cos(x+π/6)=(√15/4*√3/2)-(1/4*1/2)
cos(x+π/6)=(√45/8)-(1/8 )
cos(x+π/6)=(√45-1)/8)

Answer:
14 - 13x
Step-by-step explanation:
take 13x + 1 away from 15
15 - (13x + 1) =  15 - 13x - 1  =  14 - 13x

Answer:  D) 6</h3>
======================================================
Explanation:
Direct proportion equations are in the form y = kx, for some constant k.
The k value is the constant of proportionality. Solving for k leads to k = y/x.
For each row in the table, divide the y value over the paired x value.
- Row1:  k = y/x = 12/2 = 6
- Row2:  k = y/x = 24/4 = 6
- Row3:  k = y/x = 30/5 = 6
- Row4:  k = y/x = 54/9 = 6
Each row leads to the same k value, so the constant of proportionality is 6.
The equation y = kx updates to y = 6x. 
This line has slope 6 and y intercept 0. 
All direct proportion equations go through the origin.
