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

What is the y-intercept of the function f(x)=4 - 5x? (Hint: use the commutative property)

Tom [10]

Answer:

Therefore the y-intercept of the function is 4.

Step-by-step explanation:

Intercepts:

The line which intersect on x-axis and y-axis are called intercepts.

y-intercept: The line or function which intersect at y-axis. So when the line intersect at y-axis, X coordinate is zero.

So in the given Function Put x = 0 we will get the y-intercept

$f(x)= 4-5x$

Put x =0

$f(0)= 4-5\times 0$

$f(0)= 4-0=4$

Therefore the y-intercept of the function is 4.
