Step-by-step explanation:
<u>Average Value of a Function</u>
Given a function g(x), we can compute the average value of g in a given interval (a,b) with the equation:
We use the given data
We now compute the indefinite integral with a u-substitution
We'll use the substitution u=lnx, du=dx/x. Then
Integrating
Since u=lnx
The average value is
Since lne=1, and ln1=0
If you are asking how much he still has well he would still have 32.75
1 gallon is 3.78 L
100 sq feet needs 1 L
800 sq feet needs x
100/800 = 1/x
100x = 800
x = 800/100
x = 8 L
If you use the fact that 4 L = 1 gallon then you need 2 gallons of paint. I you use the more accurate 3.78 L then
1 gallon = 3.78 L
x gallon = 8 L
3.78 x = 8*1
x = 8/3.78
x = 2.12 gallons.
I guess you could say that 1 gallon and 1 L would do you.
Answer:
<h2>
</h2>
Step-by-step explanation:
<h3>
</h3>
<u>First of all multiply through by 7</u>
We have
<h3>
</h3>
<u>Expand the terms in the bracket</u>
That's

</h3>
<u>Add 16x to both sides</u>
That's
<h3>
</h3>
<u>Divide both sides by 30</u>
We have the final answer as

Answer:
77.786 m
Step-by-step explanation:
The shortest length of the rope used cabnbe obtained using trigonometric relation :
Shortest length of the rope = hypotenus
Using the relation :
Cos θ = Adjacent / hypotenus
Adjacent = 50 ;θ = 50°
Cos 50 = 50 / hypotenus
Hypotenus = 50 / cos 50
Hypotenus = 77.786 m
