Find the height and area of the equilateral triangle

sergejj [24]

As here we are given with an equilateral triangle, whose side is 3 cm, and we need to find the height and area of the equilateral triangle. So, for this let's recall that, the area of any equilateral triangle with side a is given by ;

${\boxed{\bf{Area_{(Equilateral\:\: Triangle)}=\dfrac{\sqrt{3}}{4}a^{2}}}}$

So, if we substitute a = 3, in our Formula, it will yield to

${:\implies \quad \sf Area_{(Equilateral\:\:Triangle)}=\dfrac{\sqrt{3}}{4}(3)^{2}}$

${:\implies \quad \sf Area_{(Equilateral\:\:Triangle)}=\dfrac{\sqrt{3}}{4}(9)}$

${:\implies \quad \boxed{\bf{Area_{(Equilateral\:\:Triangle)}=\dfrac{9\sqrt{3}}{4}\:\:cm^{2}}}}$

Now, as we know that, for any triangle we also have a formula that is ;

${\boxed{\bf{Area_{(Triangle)}=\dfrac{1}{2}\times Base\times Height}}}$

Now, Here as the triangle is equilateral, so it's base will just be same 3, and if we let height be H, so we will be having

${:\implies \quad \sf \dfrac{1}{2}\times 3\times H=\dfrac{9\sqrt{3}}{4}}$

${:\implies \quad \sf H=\dfrac{9\sqrt{3}}{4}\times \dfrac23}$

${:\implies \quad \boxed{\bf{Height=\dfrac{3\sqrt{3}}{2}\:\:cm}}}$

Oil is pumped continuously from a well at a rate proportional to the amount of oil left in the well. Initially there were 5 mill

maks197457 [2]

Let r be the rate at which oil production is decreasing from the well. Then:
5000000 x r^6=2500000
r^6=.5
ln r^6=ln .5
6 ln r=-0.69314718055994530941723212145818
ln r=-0.11552453009332421823620535357636
r=e^-0.11552453009332421823620535357636=.891
Since the oil production is only 0.891 of the previous year, the annual rate of loss is 0.109, or 10.9%, growing annually
A.3000000=5000000x(.891)^t
.6=0.891^t
t=4.42 years
Oil is being pumped at .60 of original production
B.250000=5000000 x 0.891^t
.05=.89^t
t=25.96 years
