Answer:

$397.90

Step-by-step explanation:

We have to calculate the cost to fill the drum with oil.

The formula to get the volume of the drum is V = πr²h

V = 3.14×(1.2)²×4 = 18.09 feet³

Now, find the cost of oil to fill the drum:

Cost = Volume × cost = 18.09×22 = $397.90

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

1. A line passes through (9, -9) and (10,-5).
jenyasd209 [6]

Answer:

1. y+5=4x-40

2.y=4x-45

Step-by-step explanation:

To get the slope of a line you do y₂-y₁/x₂-x₁ so we plug in the values -9+5/9-10 and we get -4

Point-slope form states y-y₁=m(x-x₁) where m is the slope so plug in the values we get y+5=4(x-10) and you get y+5=4x-40 then turn this equation into y=mx+b and get y= 4x-45

The endpoints of a regular pentagon are (-1,4) and (2,3). What is the perimeter of the Pentagon?
ryzh [129]

the assumption being that the endpoints are two continuous points in the pentagon, Check picture below.

\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-1}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{3})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[2-(-1)]^2+[3-4]^2}\implies d=\sqrt{(2+1)^2+(3-4)^2} \\\\\\ d=\sqrt{9+1}\implies d=\sqrt{10}~\hfill \stackrel{\stackrel{~\hfill \stackrel{\textit{5 sides}}{}}{\textit{perimeter of the pentagon}}}{5\sqrt{10}}

How do I do this because it's really confusing haha
netineya [11]
A = 1.5
B = -1/3
C = -4/3

A is a positive so there is only one possibility
B is in between 0 and -1, so it has to be -1/3
C is below -1 and so its the improper fraction
