Check the picture below
notice, the length cannot be a negative value.. so is not -17
A) 6
Replace the y with 6
4(6)+13=37
Multiply
24+13=37
Add
37=37
I hope this helps :)

#2) Use quotient rule
![\frac{f'g - fg'}{g^2}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%27g%20-%20fg%27%7D%7Bg%5E2%7D)
Remember for solving log equations:
![e^{ln x} = x](https://tex.z-dn.net/?f=e%5E%7Bln%20x%7D%20%3D%20x)
#3) Derivative of tan = sec^2 = 1/cos^2
Domain of tan is [-pi/2, pi/2], only consider x values in that domain.
#4 Use Quotient rule
#9 Use double angle identity for tan
![tan(2x) = \frac{2tan x}{1-tan^2 x}](https://tex.z-dn.net/?f=tan%282x%29%20%3D%20%5Cfrac%7B2tan%20x%7D%7B1-tan%5E2%20x%7D%20)
This way you can rewrite tan(pi/2) in terms of tan(pi/4).
Next use L'hopitals rule, which says the limit of indeterminate form(0/0) equals limit of quotient of derivatives of top/bottom of fraction.
Take derivative of both top part and bottom part separately, then reevaluate the limit. <span />
1. 360*0.40=144
so they said 40% reggie collected main mor than 40% collected so you need to do add like 360+144=504
the answer 504
2. you need to do new to old
the new is 15 old is 799
799-15=784x100
the high number is 799
so you need to do 799 divided by 100=7.99
now 784 divided by 7.99=98.12
the answer is 98.12
3/8 times 8/3 = 1
Answer=8/3
