Answer:

25

Step-by-step explanation:

it's so easy to get to know

Step-by-step explanation:

Given

f(x) = 2x - 5

f^-1(x) = ?

we know

Let

y = f(x)

Or y = 2x - 5

Now Interchanging the role of x and y we get

x = 2y - 5

or 2y = x + 5

therefore y = (x+5) / 2

Therefore, f^-1(x) = ( x + 5 ) / 2

Hope it will help :)❤

A barrel of crude oil contains about 5.61 cubic feet of oil. How many barrels of oil contained in 1 mile (5280 feet) of a pipeli
8_murik_8 [283]
1)volume of the  pipeline

The pipeline is a cylinder, therefore;
Volume (cylinder)=πr²h
r=radius
h=height of the cylinder

diameter=6 in*(1 ft / 12 in)=0.5 ft
raius=diameter / 2=0.5 ft / 2=0.25 ft.
height=5280 ft

Volume (pipeline)=π(0.25 ft)²(5280 ft)=330π ft³≈1036.73 ft³.


2) we calculate the number of barrel
1 mile of oil in this pipeline is 330π ft³ of oil.

1 barrel of crude------------------5.61 ft³
x----------------------------------330π ft³

x=(1 barrel*330π ft³) / 5.61 ft³=184.8 barrels

3) we calculate the price.

1 barrel---------------$100
184.8 barrels----------  x

x=(184.8 barrels * $100) / 1 barrel=$18,480

Solution: ≈$18,480

52,908 round to the nearest hundred.
IrinaVladis [17]

The hundredth is the 3rd number after the decimal place (so the 9). Look at the number before it and if it is 5 or above then round it to the next hundredth. In this case it is only a zero so we don't change the 9 just substitute it 0's. Therefore the answer is 52,900.

If you need further help let me know, hope this helped you.

For this case, what you should see is where the graph cuts the x-axis.
 Notice that the graph cuts to the x axis in three different points.
 Then the value of x that is in the domain of the function in this case is:
 x = 1
 For this value of x the function is zero.
 Answer:
 x = 1
