A drum of oil has a height of 4 feet and a radius of 1.2 feet. the oil cost $22 per cubic feet.
blondinia [14]
Well, first we should calculate just how much volume the drum can carry.
The formula we should use is πr^2(h):
π((1.2 ft)^2)(4 ft)
π(1.44 ft^2)(4 ft)
5.76π ft^3 ≈ 18.1 ft^3
Thus is costs:
$22 * 18.1 ft^3
$398.2

Give the equation of the horizontal asymptote shown below.
Oxana [17]
Polynomial division yields

\dfrac{7x^2}{x^2+5}=7-\dfrac{35}{x^2+5}

As x\to\pm\infty, you have the remainder term approaching 0, so the horizontal asymptote is the line y=7.
