Properties of Logarithms

We'll recall below the basic properties of logarithms:

$log_b(1) = 0$

Logarithm of the base:

$log_b(b) = 1$

Product rule:

$log_b(xy) = log_b(x) + log_b(y)$

Division rule:

$\displaystyle log_b(\frac{x}{y}) = log_b(x) - log_b(y)$

Power rule:

$log_b(x^n) = n\cdot log_b(x)$

Change of base:

$\displaystyle log_b(x) = \frac{ log_a(x)}{log_a(b)}$

Simplifying logarithms often requires the application of one or more of the above properties.

Simplify

$\displaystyle log_\frac{1}{2}(64)$

Factoring $64=2^6$ .

$\displaystyle log_\frac{1}{2}(64)=\displaystyle log_\frac{1}{2}(2^6)$

Applying the power rule:

$\displaystyle log_\frac{1}{2}(64)=6\cdot log_\frac{1}{2}(2)$

Since

$\displaystyle 2=(1/2)^{-1}$

$\displaystyle log_\frac{1}{2}(64)=6\cdot log_\frac{1}{2}((1/2)^{-1})$

Applying the power rule:

$\displaystyle log_\frac{1}{2}(64)=-6\cdot log_\frac{1}{2}(\frac{1}{2})$

Applying the logarithm of the base:

$\mathbf{\displaystyle log_\frac{1}{2}(64)=-6}$

How do you do this??

Nana76 [90]

Answer:

A-2, B-5, C-1, D-6, E-3, F-4

Step-by-step explanation:

The A would be the function x^3, so it would be the volume of a cube which is #2

B is probably the temperature graph, because it is warmest in the middle of the day and cooler at both ends, so that is #5

C is probably the age of an oak tree because it starts at 0, and grows linearly. #1

E is #3 because it is decreasing and so is the fuel in the tank.

F is the area of a triangle one, because that would be a quadratic function (half of a parabola)#4

D is the car wash, it doesn't start at 0 because the x-axis is the time of day. #6

One angle of a right-angled triangle is 60 grades . Find the other angle in degree.

eduard

Answer:

30°

Step-by-step explanation:

This right triangle has :

right angle (90°)
One angle of 60°

=========================================================

Solving :

We know the angle sum of a triangle is 180°.

⇒ x + 90° + 60° = 180°

⇒ x + 150° = 180°

⇒ x = 30°

What is 28 tiles in 7 ros. (It has to be a divison equation)

raketka [301]

If 28 tiles is placed in 7 rows then each row has 4 tiles.

Step-by-step explanation:

The total number of tiles given =28.

The number of rows = 7.

The number of tiles in each row is given by diving the total number of tiles given by the number of rows.

No of tiles in each row= $\frac{total number of tiles}{number of rows}$ .

No of tiles in each row = $\frac{28}{7}$ .

No of tiles in each row = 4.

Note: You can replace the values according to the given values.
