Decide whether the following statements are always, sometimes, or never true.If n is a real number, then 0n=0 .
The following statement that if n is a real number, then 0n = 0 is always true.
The given question states that we have to determine whether the given statement is always true or sometimes true or never true.
The statement given in this question is that if n is a real number, then 0 n = 0.
To solve this question, it us important that we are familiar with real numbers.
Real numbers comprise of both rational numbers as well as irrational numbers. Rational numbers include natural number, whole numbers, fractions, etc. while irrational numbers consist of recurring decimal numbers such as √3, pi, etc.
We know that any real number multiplied with 0 will always return 0 as the answer.
Hence, we can say that the statement that if n is a real number, then 0 n = 0 is always true.
Therefore, we get the following statement that if n is a real number, then 0n = 0 as always true.

Suppose you know the measures of all three angles of a triangle. Can you use the Law of Sines to find the lengths of the sides? Explain.
Answer:
No
Step-by-step explanation:
Without any side lengths, the most three angles can determine is similarity, not congruency. This means you can determine the ratio of the lengths of the sides, but not any of the sides individually.
The solution set of |2x − 2| > 2 is the set of all x-values where the graph y = |2x − 2| ? the line y = 2.
a.)is above
B.)is below
c.)intersects
d.) does not intersect
!100! POINTS!!!!!!
Answer:
a.)
Step-by-step explanation:
|2x - 2| > 2 (greater than 2)
the dilution set is the set of all x values, for which this inequality is true.
and that means
|2x - 2| has to have greater value than the value 2, which is represented by the constant, horizontal line y = 2.
the y values are aligned with the y-axis, which goes up and down. the higher up, the larger the y value.
so, only the values of |2x - 2| higher than 2 keep the inequality true.
so, a.) is the right answer. it is above the line.
b.) below would mean "< 2".
c.) intersects would mean "= 2".
d.) does not intersect would mean "<> 2".
please consider, the intersection points with the line are NOT included, because we have "> 2".
if we had to include the intersection points, it would have to be ">= 2".
m∠W=73°. Find the measure of the complement of ∠W.
115°
15°
17°
107°
The measure of the angle that complements m∠W is 17°. Option C
What are complementary angles?Complementary angles are defined as angles that sum up to 90 degrees.
They are also called angles at right angle.
Example:
If x and y are termed complementary angles, then
x + y = 90°
From the information given, we have that;
m∠W is complementary to another unknown angle x
This is represented as;
x + m∠W = 90°
But m∠W = 73°
Substitute the value into the equation
x + 73° = 90°
collect like terms
x = 90 - 73
x = 17°
Thus, the measure of the angle that complements m∠W is 17°. Option C

What is the height, h, of the rectangular prism shown below?
Round your answer to the nearest tenth.
The height (h) of this rectangular prism is equal to 3 units.
What is Pythagorean theorem?Pythagorean theorem can be defined as a mathematical expression in Euclidean geometry that can be used to solve for any of the three (3) side lengths of a right triangle.
How to determine the height (h) of this rectangular prism?In order to determine the height (h) of this rectangular prism, we would first of all determine the diagonal of the base by applying Pythagorean theorem:
d² = l² + b²
d² = 4² + 3²
d² = 16 + 9
d² = 25
d = √25
d = 5 units.
Therefore, the diagonal of the base of this rectangular prism is equal to 5 units.
Now, we can determine the height (h) of this rectangular prism:
x² = d² + h²
h² = √34² - 5²
h² = 34 - 25
h² = 9
h = √9
Height, h = 3 units.
Therefore, the height (h) of this rectangular prism is equal to 3 units.

Choose the numbers that are equivalent to 2 7/9.
The equivalent fractions here are: 14/18 , 21/27 , 28/36 , 35/45 , 42/54.
Given, the number 7/9
7/9 = (7/9 × 2/2) = 14/18
7/9 = (7/9 × 3/3) = 21/27
7/9 = (7/9 × 4/4) = 28/36
7/9 = (7/9 × 5/5) = 35/45
7/9 = (7/9 × 6/6) = 42/54
hence the equivalent fractions here are:
14/18 , 21/27 , 28/36 , 35/45 , 42/54
Equivalent fractions are those fractions that reflect the same value even if they may have distinct numerators and denominators. For instance, the fractions 9/12 and 6/8 are comparable as both, when simplified, equal 3/4.

For each pair of functions, find f(g(x)) and g(f(x)) .

A composite function exists as a function that depends on another function. A composite function exists formed when one function exists substituted into another function.
The value of f(g(x)) = (2x-6)/2 and g(f(x)) = x - 6.
What is meant by composition function?In mathematics, function composition exists as an operation ∘ that takes two functions f and g, and has a function h = g ∘ f such that h(x) = g. In this operation, the function g exists used to the result of applying the function f to x.
Function composition is a mathematical procedure where two functions, f, and g, are taken and a function, h = g ∘ f, is produced such that h(x) = g(f(x)). The function g exists used in this operation on the outcome of applying the function f to x.
Let the given functions be f(x) = x-3/2 and g(x) = 2x - 3
f(g(x)) = f(2x-3)
simplifying the above equation, we get
f(g(x)) = f(2x-3) = ((2x-3) - 3)/2
f(g(x)) = f(2x-3) = (2x-6)/2
f(g(x)) = (2x-6)/2
g(f(x)) = g(x-3/2)
simplifying the above equation, we get
g(f(x)) = g(x-3/2) = 2((x-3)/2) - 3
g(f(x)) = g(x-3/2) = x - 6
g(f(x)) = x - 6
Therefore, the value of f(g(x)) = (2x-6)/2 and g(f(x)) = x - 6.

If BD = 3, then it means that CD is also equal to 3 by definition of Isosceles triangle.
What is the missing length of the triangle?
We are given a triangle with the condition that BA ≅ CA. This means that side BA has a length equal to that of side CA.
Now, an Isosceles triangle is defined as a triangle that has at least two sides of equal length. This means that the given triangle ABC is an Isosceles triangle.
Now, since Triangle ABC is an Isosceles triangle, it means that when we draw a perpendicular line through the point joining the two equal sides, it bisects the third side of the triangle.
Thus, it means that BD is congruent to CD.
If BD = 3, then it means that CD is also equal to 3 by definition of Isosceles triangle.

f(x)=b x and g(x)=logbx are inverse functions. Explain why each of the following is true.
a. The translation f₁(x)=b x-h of f is equivalent to a vertical stretch or compression of f .
The function f₁(x) can be either vertical stretch or vertical compress: TRUE
What do we mean by Logarithmic Function?The following is the formula for basic logarithmic functions: Where b > 0, f(x) = logbx(r), y = logbx.It is the reciprocal of the exponential function x=b∧y.Log functions are denoted by natural logarithm (ln) and common logarithm (log).Here are a few examples of logarithmic functions:
f(x) = ln (x - 2)g(x) = log2(x + 5)-2h(x) = 2 log x, etc.So,
Given function:
f(x) = bˣg(x) = logbxThen,
f₁(x)=b^(x-h)f₁(x)=b^x/b^hNow, Put bˣ=f(x):
f₁(x)=f(x)/b^hf₁(x)=b^(-h)f(x)f₁(x)=c f(x)We discovered that:
c=b^(-h)So, depending on the values of b and h, c can be greater than or less than one.
Therefore, the statement "the function f₁(x) can be either vertical stretch or vertical compress" is TRUE.

A customer should buy minimum 16 boxes of pavers.
In this question, a customer is ordering brick pavers to cover a rectangular walkway that is 3 feet by 15 feet and a square sitting area that is 6 feet on a side.
First we find the total area that will be covered by pavers.
Area of rectangle = length × width
Area of rectangle = 15 × 3
Area of rectangle = 45
And the area of square = side²
area of square = 6²
area of square = 36
So, the total area would be,
Total area = area of rectangle + area of square
Total area = 45 + 36
Total area = 81
So, the total area is 81 square feet.
one box of pavers covers 5.28 square feet.
So using unitary method,
81 / 5.28
= 15.534
≈ 16 boxes
This means, approximately 16 boxes will require to cover the above area.
Therefore, the customer should buy minimum 16 boxes of pavers.
