Apply l'Hopital's rule:

where
![\displaystyle\frac{\mathrm d}{\mathrm dx}\left[\int_\pi^x(1+\tan(t))\,\mathrm dt\right]=1+\tan(x)](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D%5Cleft%5B%5Cint_%5Cpi%5Ex%281%2B%5Ctan%28t%29%29%5C%2C%5Cmathrm%20dt%5Cright%5D%3D1%2B%5Ctan%28x%29)
follows from the fundamental theorem of calculus.
First step to solve (v+6)(v-6)=0 is to use FOIL and dd the multiplication
v^2-6v+6v-36=0
v^2-36=0\ or v^2=36
we need to take the square root from both sides so
v=6 and v=-6
<span>v = {-6, 6}</span>
Sum of interior of any polygon = (n - 2) x 180
so in this case n = 11
<span>the sum of measure of interior angles
= (11 - 2) x 180
= 9 x 180
= 1620
answer
1620</span>
The percent it needs to.grow each year is.4 percent because the investment wants.to.increase by factor.of.5. in 20 years. 20 divided by 5 would 4 percent each year.
