Given that Angles A and B are complementary to each other, the numerical value of x is 15.

Complementary angles are angles that sum up to 90 degrees.

Given the data in the question;

Since Angles A and B are complementary to each other, the sum of angle A and B is 90 degrees.

Measure of angle A + Measure of angle B = 90°

Plug in the given values and solve for x.

41 + (2x + 19) = 90

41 + 2x + 19 = 90

2x + 60 = 90

2x = 90 - 60

2x = 30

x = 30/2

x = 15

Given that Angles A and B are complementary to each other, the numerical value of x is 15.

Answer:

number 0

Step-by-step explanation:

The identity property of addition states that when zero is added to any real number, the number does not change. Thus, the number "0" is called the additive identity of a matrix.

plane's average change of altitude per minute 0.35 miles descended per minute.

What is proportion ?

A proportion is an equation based on the equality of two ratios.

Here it is given that :

To avoid a storm, a passenger-jet pilot descended 0.14 mile in 0.4 minute and it is to find the plane's average change of altitude per minute and to find that we divide 0.14 miles with 0.4 minutes it will give us the descended  

passenger-jet pilot does in a minute that is plane's average change of altitude :

In 0.4 minute  = 0.14 miles descended

In 1 minute = 0.14/0.4 miles descended

In 1 minute = 0.35 miles descended

Therefore, plane's average change of altitude per minute 0.35 miles descended per minute.

Answer:

5a+2b+10

Step-by-step explanation:

Let's simplify step-by-step.

a(6−1)+3b−b(2−1)+10

=5a+3b+−b+10

Combine Like Terms:

=5a+3b+−b+10

=(5a)+(3b+−b)+(10)

=5a+2b+10

Use the identity a^2-b^2 = (a+b)(a-b) to factor 16a^2 - 9b^2. The two terms are perfect square thus find a and b by taking the square roots. Complete the factoring of a^2 - b^2

16a^2−9b^2

a=√16a^2=4a

b=√9b^2=3b

a^2−b^2=(4a)^2−(3b)^2

Substitute: a^2-b^2 = (a+b)(a-b)

Answer to this question is:

Domain of given function is (-∞,0)∪(0,∞),{x|x≠0}

Range of given function is (0,∞),{y|y>0}

Inverse of given function is √x/x,-√x/x

The domain is all values of x that make the expression defined.The entire range of independent variable values is the domain of a function.

This definition can be stated simply as follows: The domain is the collection of all x-values that can be used to make the function "work" and produce actual y-values.

When choosing the domain, keep in mind that a fraction's denominator (bottom) cannot be 0.

Interval Notation:(-∞,0)∪(0,∞)

Set-Builder Notation:{x|x≠0}

The set of all valid y values constitutes the range.Graph may be used to find the values.

The intercepts and the standard form of each polynomial are listed below:

In this case we need to find the intercepts of each quadratic equation and transform each quadratic equation into standard form. The x-intercept correspond with each of the roots of the polynomial and the y-intercept is found by evaluating the expression at x = 0.

Now we proceed to find each element:

Case 1

x-Intercept

x = - 4 or x = 6

Standard form

f(x) = (x + 4) · (x - 6)

f(x) = x² - 2 · x - 24

y-Intercept

f(0) = - 24

Case 2

x-Intercept

x = 1 / 4 or x = 3

Standard form

f(x) = (2 · x - 4) · (x - 3)

f(x) = 2 · (x - 2) · (x - 3)

f(x) = 2 · (x² - 5 · x + 6)

f(x) = 2 · x² - 10 · x + 12

Step-by-step explanation:

C describes theta moving +5 units. In math, negative goes left, negative goes left. However, since there are no negative values involved, we can assume that theta will move 5 units to the left in terms of absolute value, which excludes the need for the negative to be moved left. Therefore, the answer is C due to this change.

Answer: 31.4

Step-by-step explanation:

the four is in the tenth place and we are rounding to that place.

The given decimal number is rounded to the nearest tenth as 31.4.

The given decimal number is 31.4.

Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.

Here, in 31.40 digit in the hundredths place is 0, which is less than 5.

So, the digit in the tens place remain same and digits after tens place becomes zero.

That is, 31.4

Therefore, the given decimal number is rounded to the nearest tenth as 31.4.

It should be noted that rewriting the equation y=3(x-5)² +1 in another form is y = 3x² - 30x + 76.

It should be noted that the information is that we should rewrite the equation y=3(x-5)² +1 in another form.

This will be illustrated as:

y = 3(x-5)² + 1.

It should be noted that (x - 5)² will be:

= (x - 5)(x - 5)

= x² - 5x - 5x + 25

= x² - 10x + 25

y = 3(x-5)² + 1.

y = 3(x² - 10x + 25) + 1

y = 3x² - 30x + 75 + 1

y = 3x² - 30x + 76

In conclusion, it should be noted that rewriting the equation y=3(x-5)² +1 in another form is y = 3x² - 30x + 76.

The set of numbers that are integers but not whole numbers or natural numbers is {-2, -3, -4}

From the question, we are to determine the set of numbers that are integers but not whole numbers or natural numbers

An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero. E.g -5, -13, 5, 0, -3, 78, 15, etc

Whole numbers is a collection of all the basic counting numbers and 0. E.g 0, 1, 2, 3, 4, 5 etc

Natural numbers are the numbers that start from 1 and end at infinity. E.g 1, 2, 3, 4, 5, 6, etc

Hence, the set of numbers that are integers but not whole numbers or natural numbers is {-2, -3, -4}

Expression as a single natural logarithm is ln 64/64 = ln 1.

ln 1 is the converted from 2 ln 8-3 ln 4 to a single natural logarithm.

We need to convert 2 ln 8-3 ln 4 as a single natural logarithm.

First apply power property

⇒ ln 8² - ln 4³

⇒ ln 64 - ln 64

Now, applying quotient property

⇒ ln 64/64 = ln 1

Here, we finally converted 2 ln 8-3 ln 4 to a single natural logarithm ln 1.

The inverse of an exponential function, the natural log is the logarithm to the base of the number e. Natural logarithms are unique varieties of logarithms that are employed in the treatment of time and growth-related issues.

The distinction between log and ln is that log is expressed in terms of base 10, while ln is expressed in terms of base e. As an illustration, log of base 2 is denoted by log2 and log of base e by loge = ln (natural log).
