Differentiate function Y=Ln^2(2x+11)

Mathematics
1 answer:
Studentka2010 [4]3 years ago
7 0

Answer:

\frac{\textbf{dy}}{\textbf{dx}}=\frac{\textbf{2}}{\textbf{x}}+\frac{\textbf{4}}{\textbf{11}}

Step-by-step explanation:

Given function is

y=\log^2(2x+11)

the above function can be written as

y=2\log(2x+11)

(By using the formula \log x^n =n \log x)

Now differentiate the above function with respect to x on both sides

\frac{dy}{dx}=2\left[\frac{1}{2x+11}\right]\ (2)  

(By using formula \log x=\frac{1}{x} and \log (ax+b)=\left(\frac{1}{ax+b}\right){(a)}=\frac{a}{ax+b} where a and b constants)

    =\frac{4}{2x+11}

    =\frac{4}{2x}+\frac{4}{11}

Therefore

\frac{dy}{dx}=\frac{2}{x}+\frac{4}{11}

1. The cost of petrol rises by 2 cents a liter. last week a man bought 20 liters at the old price. This week he bought 10 liters
AnnyKZ [126]
Answer for #1


Let the old price be
$
x
per liter. 10 liters would have cost a total of
$
10
x
.

The new price is
$
(
x
+
0.20
)
per liter. 10 liters would have cost
$
10
(
x
+
0.20
)
.

The total cost is
$
9.20
. So,



10
x
+
10
(
x
+
0.20
)
=
9.20
10
x
+
10
x
=
9.20
−
2
x
=
7.20
20
x
=
0.36




Thus, the old price was
$
0.36
per liter.
