What are functions?Functions can be defined as expression, rules or law that explains the relationship between two variables:
A dependent variablesAn independent variableIt is also important to note that the absolute value of a number is the distance of the number from zero irrespective of its direction in a number line.
Absolute value of a number must take a positive sign.
It is denoted with the symbol '| | '
Given the expression;
| -4b - 8 | + | -1 - b²| + 2b
Substitute the value of b as -3
We have;
|-4(-3) - 8| + |-1 - (-3)²| + 2(-3)

Write each equation in logarithmic form.
8²=64
We get the equation in logarithmic form as log₈ 64 = 2
A “logarithmic equation” is an equation which involves the “logarithm” of any expression which is containing a variable.
Now, we have been given an equation:
8² = 64
We need to write it in the logarithm form.
We know that, it will be written as:
log₈ 64 = 2
Since the power goes after the equal sign, so 2 is placed after the equal sign.
The actual value is taken after log, so 64 is placed there and the base number is taken as the base for the log, so 8 is taken as the base for the log.
Therefore, we get the equation in logarithmic form as log₈ 64 = 2

6.961 x 10^27 as a percentage?
The number given as 6.961 x 10^27 as a percentage is 6.961 x 10^29%
How to express the number as a percentage?The number is given as
6.961 x 10^27
To express the number given as 6.961 x 10^27 as a percentage, we simply multiply the number by 100%
So, we have:
6.961 x 10^27 = 6.961 x 10^27 * 100%
Express 100 as 10^2
So, we have:
6.961 x 10^27 = 6.961 x 10^27 * 10^2%
Apply the law of indices, when evaluating the product
So, we have:
6.961 x 10^27 = 6.961 x 10^29%
Hence, the number given as 6.961 x 10^27 as a percentage is 6.961 x 10^29%

Where is the point (-3,1) located when it is translated four units left and two units up 
Answer:
-5,3. You crawl before you can walk.
Step-by-step explanation:
Answer:
(-7, 3)
Step-by-step explanation:
Original point: (-3, 1)
So original x = -3
4 units left means x coordinate is decreased by 4
So, new x-coordinate = -3 - 4 = -7
Original y coordinate = 1
2 units up means y coordinate increases by 1
So new y-coordinate = 1 + 2 = 3
Translated point = (-7, 3)

A quadratic function is shown on the graph.
an upward opening parabola beginning with closed circle at negative 2 comma 4, which decreases to a vertex at 0 comma 0 and then increases to an open circle at 3 comma 9
What is the range of the function?
{x | −2 ≤ x < 3}
{x | −2 < x ≤ 3}
{y | 0 ≤ y < 9}
{y | 0 < y ≤ 9}
The range of the quadratic function is {y |0 ≤ y < 9}
What is the range of a function?The range of a function is the set of output values of the graph. This in other words mean the range of a function is the set of y values of the graph.
How to determine the range of the function?From the question, we have the following parameters:
The parabola opens upwardVertex = (0, 0)Closed circle point = (-2, 4)Open circle point = (3, 9)Write out the vertex
So, we have
Vertex = (0, 0)
Remove the x value
y = 0
From the question, we have
The parabola opens upward
This means that the vertex is a minimum
So, the range is
y ≥ 0
Rewrite as
0 ≤ y
Recall that:
Closed circle point = (-2, 4)
Open circle point = (3, 9)
Remove the x values
Closed circle point = 4
Open circle point = 9
Remove the smaller y value
Open circle point = 9
This means that the highest value of y is at open circle point = 9
This is represented as
y < 9
So, we have
0 ≤ y and y < 9
Combine both
0 ≤ y < 9
Rewrite properly as
{y |0 ≤ y < 9}
Hence, the range of the quadratic function is {y |0 ≤ y < 9}

A function that represents the meters Jackie can run in any given minutes is b = 150m.
The meters she would run after 12 minutes is 1,800 meters.
How many meters can she run in 12 minutes?The independent variable is the variable that cannot be altered in the process of an experiment. The independent variable is the minutes ran by Jackie.
The dependent variable is the variable that is being measured in an experiment. It is usually affected by the independent variable. The dependent variable is the total distance that Jackie runs.
The function that represents the distance run is:
Total distance = distance run per minute x number of minutes
b = 150 x m

How do you answer 532÷4 using long division?
If we divide five hundred and thirty two by four using long division method, we obtain one hundred and thirty three.
What is long division?The term long division implies dividing repeatedly until we are able to arrive at the final result. In this case, we are asked to carry out the division of 532÷4 using long division.
First we have to divide the digits one after the other. This process is a bit iterative and takes a little time for us to do in the process of the long division.
Now; when we divide five by 4 we obtain one remainder one we then add the one that remains to thirty two and we have one hundred and thirty two.
Then we divide one hundred and thirty two by four, we can see that there are thirty three fours in one hundred and thirty two. The final result of our long division now becomes one hundred and thirty three.
Thus, if we divide five hundred and thirty two by four using long division method, we obtain one hundred and thirty three.

Using multiple line and angle theorems, the values of each of the 14 angles are given.
Using the geometry theorems :
1.)
∠2 is a right angle = 90°
2.)
∠1 + ∠2 + ∠3 = 180° (sum of angle on a straight line)
90 + ∠1 + 54° = 180°
∠1 = (180 - 144) = 36°
(∠2 and ∠5) ; (∠3 and ∠6) ; (∠1 and ∠4) are vertically opposite ;
Hence,
∠4 = 36°
∠5 = 90°
∠6 = 54°
∠3 = ∠8 = 54° (corresponding angles)
∠9 + ∠8 = 180° (sum of angle on a straight line)
∠9 = (180 - 54) =126°
∠7 = ∠9 = 126° (vertically opposite angles)
∠8 = ∠10 = 54° (vertically opposite angles)
∠4 = ∠13 = 36° (corresponding angles )
∠12 + ∠13 = 180° (sum of angle on a straight line)
∠12 = (180 - 36) =126°
∠11 = ∠13 = 36° (vertically opposite angles)

test tube to be 100.5 ml. In fact, the real capacity of the test tube is 100.0 ml. What percent
error has resulted from the student's assumption?
The percent error that has resulted from the student's assumption is 0.5%.
The percent error is used to calculate the percentage error between an experimental measured value and a theoretical actual value.
Percentage error formula = |E-T|/|T| x 100
where E is the experimental value and T is the theoretical value.
Given, the experimental measured value (E) = 100.5 ml and theoretical actual value (T) = 100.0 ml
By using the Percentage error formula, simply put the value of the capacity of the test tube which was found by the student as an experimental measured value and real capacity of the test tube as a theoretical actual value, we get
=|(100.5−100.0)||100.0| × 100
=0.5/100×100
