Use complete sentences to describe how logarithms can aid in difficult calculations.
Burka [1]
First, it is to be understood that logarithms allow a person to subject a number as an exponent of a base. As an example of ways in which logarithm is used to aid us in difficult calculations is when we calculate for the pH of a substance which has a formula of,
                                       pH = -log[H+]

Which measure of variation is found by placing the data in ascending order and subtracting the lowest value from the highest val
igomit [66]

Answer:

Range

Step-by-step explanation:

The range of a given set of data is the difference between the largest value and the smallest value in the data. For convenience and ease in the calculation, it is advisable to place the data in ascending order.

For example, given the following set of data:

4,9,5,6,2

To find the range;

<em>=> First arrange the data in ascending order</em>

2,4,5,6,9

<em>=> Find the smallest and largest numbers and then find their difference.</em>

Since the data has been arranged, it is obvious to see that the smallest number is <em>2</em> and the largest number is <em>9.</em>

Therefore the;

range = 9 -2 = 7

Help me with this please
Elina [12.6K]

Answer:

1) <2 ; 60

2) <3 ; 60

3) <4 and <3. <4 = 120 and <3 = 60

4) <1, <3, and <4 = 125. <2 = 55

Step-by-step explanation:

1)

Corresponding angles are equal

2)

Alternate interior angles are equal

3)

<4 and <3 are same-side interior angles. This makes them supplementary angles

<4 = 120

<3 = 60

4)

<1 = <4 = <3. All of these angles equal 125.

<2 + <1 = 180

<2 + 125 = 180

<2 = 55

The vertex of the parabola below is at the point (-4,-2) wich of the equations below could be the one for this parabola
MrRissso [65]

The parabola with with a vertex at (-4,-2) represents any member of parabolas with the equation y(x)=a(x+4)^2-2 where a is any real number with the exception that  a\neq 0.

The reason any equation  of the form y(x)=a(x+4)^2-2 works is that there are an infinite number of parabolas with a vertex at (-4,-2). All of these parabolas are formed by applying some transformation that involves a vertical translation of -2 and a horizontal translation of -4 on the parabola y=x^2. The different variations are archived by varying the constant a.  When a is negative, the parabolas will face downwards. When a is negative, the parabolas will be face downwards.
