Find volume
v=(1/3)hpir^2
r=60
h=210
pi=3.14 for this questio
v=(1/3)(210)(3.14)(60^2)
v=(1/3)(210)(3.14)(3600)
v=(70)(3.14)(3600)
v=(70)(3.14)(3600)
V=791,280 cm3
rate of 1099 er hour
drained out is zero
amount drained total=volume of cone=1099 times number of hours
lets say number of hours=x
1099x
791,280=1099x
divide both sides by 1099
720=x
answe ris 720 hours

Hello :
<span>y = 3x2 + 24x - 1
= 3(x²+8x) -1
= 3 (x² +2(4)(x) +4²- 4² ) -1
= 3((x+4)² -16)-1
y = 3(x+4)² - 49
</span><span>the line of symmetry is : x= - 4</span>
