Answer:
Step-by-step explanation:
m= month
3÷100= 0.03
0.03×500=<u>$15</u>
$15/m
$15×5×12=$900
$500-$900= <u> </u>
<u>Answer: -$400</u>
Answer: 13.6% needed more time but then said no. 25.6% were contacted but said no.
To do this problem, you have to create a tree diagram with all of the possibilities.
The first branch separates with 20% not being contacted and 80% being contacted.
Then, the 80% branch can be broken into 12% saying no and 68% needing more time (multiply by 15% and 85%).
Then, the 68% branch can be broken into 54.4% going and 13.6 not going (multiply by 80% and 20%).
With the tree diagram, just pick the percents that you need.
OK: slope is rise/run so 6-1/0--1=5/1
So, 5/1 or 5 is your slope
With this info you can exchange 1 and there you got your answer.
So:
![\frac{\cos^{2}x-1}{\cos x}=-\tan x\sin x \Rightarrow \frac{\cos^{2}x-\left(\cos^{2}x + \sin^2 x\right)}{\cos x}=-\tan x\sin x \Rightarrow[tex]\frac{-\sin^2x}{\cos x}=-\tan x\sin x \Rightarrow \frac{-\sin x \sin x}{\cos x}=-\tan x\sin x \Rightarrow](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ccos%5E%7B2%7Dx-1%7D%7B%5Ccos%20x%7D%3D-%5Ctan%20x%5Csin%20x%20%5CRightarrow%20%5Cfrac%7B%5Ccos%5E%7B2%7Dx-%5Cleft%28%5Ccos%5E%7B2%7Dx%20%2B%20%5Csin%5E2%20x%5Cright%29%7D%7B%5Ccos%20x%7D%3D-%5Ctan%20x%5Csin%20x%20%5CRightarrow%5Btex%5D%5Cfrac%7B-%5Csin%5E2x%7D%7B%5Ccos%20x%7D%3D-%5Ctan%20x%5Csin%20x%20%5CRightarrow%20%5Cfrac%7B-%5Csin%20x%20%5Csin%20x%7D%7B%5Ccos%20x%7D%3D-%5Ctan%20x%5Csin%20x%20%5CRightarrow)
