HELP!!!!!

podryga [215]

Solve for the x-max or h :\
$-b/(2a)=-8/(2*-2)=2=k$
plug it in to equation to get k:/
$y(2)=-2(2)^2+8(2)+3$
-8+16+3=11=k
$y=a(x-2)^2+11
$
solve for a by pluging (0,0)
then a= -11/4
$y=-11/4(x-2)^2+11$

The cost of painting the total outside surface of a closed cylindrical tank at 60 paise per meter squae is Rs237.60. The height

valkas [14]

Answer:

$volume=509.25 dm^{3}$

Step-by-step explanation:

Curved surface area= $\frac {237.6}{0.6}=396 dm^{2}=2\pi R(R+H)$ where R is radius and H is height

Since H=6R then curved surface area= $2\pi R(R+6R)=14\pi R^{2}$

Therefore,

$396 dm^{2}=14\pi R^{2}$ and making R the subject

$R=\sqrt {\frac {396}{14\pi}}=\sqrt {(9.003622)}= 3.000604 m$

Therefore, H=6R=6*3.000604=18.00362 m

$Volume=\pi R^{2}H=\pi*3.000604^{2}*18.00362=509.2453 dm^{3}$

Therefore, $volume=509.25 dm^{3}$
