Differentiating a Logarithmic Function in Exercise, find the derivative of the function. See Examples 1, 2, 3, and 4.
Natasha_Volkova [10]

Answer:

dy/dx = 2/x

Step-by-step explanation:

y = In x^2

Let u = x^2

du/dx = 2x

y = In u

dy/du = 1/u

dy/dx = dy/du × du/dx = 1/u × 2x = 1/x^2 × 2x = 2/x

dmitriy555 [2]
Numbers are:

2x+1, 2x+3, 2x+45

Sum:

2x+1+2x+3+2x+5=111
6x=111-9
6x=102
x=17

Smaller = 2x+1 = 35

Which table shows a proportional relationship between x and y?<br> Plz Help
Nastasia [14]

Answer:

The proportional table in the attached figure

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>

<em>Verify each table</em>

Find the value of the constant of proportionality k for each ordered pair of a table.

k=\frac{y}{x}

If all the values of k are the same, then the table represent a proportional relationship between x and y

Table 1

For x=1, y=2 ----> k=\frac{2}{1}=2

For x=2, y=4 ----> k=\frac{4}{2}=2

For x=3, y=8 ----> k=\frac{8}{3}=2.7

The values of k are not equal

so

This table not represent a proportional relationship between x and y

Table 2

For x=0, y=4

The line not passes through the origin

so

This table not represent a proportional relationship between x and y

Table 3

For x=0, y=0 ----> is OK the line passes though the origin

For x=1, y=1 ----> k=\frac{1}{1}=1

For x=2, y=4 ----> k=\frac{4}{2}=2

The values of k are not equal

so

This table not represent a proportional relationship between x and y

Table 4

For x=1, y=4 ----> k=\frac{4}{1}=4

For x=2, y=8 ----> k=\frac{8}{2}=4

For x=3, y=12 ----> k=\frac{12}{3}=4

The values of k are the same

so

This table represent a proportional relationship between x and y

Anderson has been saving his earnings from mowing the neighborhood lawns. he has 70 dollars and wants to spend it all on movies.
frutty [35]
70 = 4x
x equals the number of movies 

divide both sides by 4

70 / 4 = x
17 .5 = x

Anderson will be able to go to 17 movies
