Step-by-step explanation:
The value of arctan(1) is equal to π/4 or 45 degrees.
The tangent of an angle is defined as the ratio of the length of the opposite side to the length of the adjacent side in a right triangle.
For the angle whose tangent is 1, we can visualize a right triangle where the length of the side opposite to the angle is 1 and the length of the adjacent side is also 1.
Using the Pythagorean theorem, we can calculate the length of the hypotenuse:
hypotenuse² = opposite² + adjacent²
hypotenuse² = 1² + 1²
hypotenuse² = 1 + 1
hypotenuse² = 2
hypotenuse = √2
Now, we can use the definition of the arctan function to find the angle whose tangent is 1:
arctan(1) = angle whose tangent is 1 = angle whose opposite side is 1 and adjacent side is 1
This angle is a well-known special angle in trigonometry.
It is a 45-degree angle (π/4 radians) or a quarter of a full circle.
Therefore, arctan(1) is equal to π/4 or 45 degrees.

Determine which line the point (2, -1) lies on. y = 2x + 1 y = x + 5 y = 2x - 5 y = x - 2
To determine which line the point lies on, you can just plug in one of the numbers into the equations to see if it equals out.
(2, -1) I will use the 2 and plug it in for x in the equation.
y = 2x + 1
y = 2(2) + 1
y = 5 The point does not lie on this line because when x = 2, y = 5 (2, 5)
y = x + 5
y = 2 + 5
y = 7 The point does not lie on this line because when x = 2, y = 7 (2, 7)
y = 2x - 5
y = 2(2) - 5
y = 4 - 5
y = -1 The point does lie on this line because when x = 2, y = -1 (2, -1)
y = x - 2
y = 2 - 2
y = 0 The point does not lie on this line because when x = 2, y = 0 (2, 0)
50× 3/8 how to reduce answer to lowest te
The lowest term is [tex]\frac{75}{4}[/tex].
Solution:
Given expression is [tex]50\times\frac{3}{8}[/tex]
To reduce this term to the lowest term:
[tex]$50\times\frac{3}{8}=\frac{50}{1}\times\frac{3}{8}[/tex]
Multiply the numerator and denominator.
[tex]$50\times\frac{3}{8}=\frac{150}{8}[/tex]
Now, divide the numerator and denominator by the greatest common factor.
Here 150 and 8 both have common factor 2.
So, divide numerator and denominator by 2.
[tex]$=\frac{150\div2}{8\div2}[/tex]

Find the measure of angle 5. Will someone please help me. I have to answer this one question before I can move on to another one. Please help
The measure of angle 5 is 75°.
Step-by-step explanation:
Properties of intersecting lines :
The angles formed opposite to each other at the point of intersection are called vertically opposite angles. These vertically opposite angles are congruent (same).step 1 :
From the figure, the angle (-9x-12) and angle (6x+183) are vertically opposite and are equal.
-9x-12 = 6x+183
⇒ -9x-6x = 183+12
⇒ -15x = 195
⇒ x = -(195/15) = -13
step 2 :
Substitute x= -13 in the angle (-9x-12)
⇒ (-9x-12) = -9(-13)-12
⇒ 117 - 12 = 105°
step 3 :
The measure of angle in a line is supplementary (180°).
Let angle 5 be unknown value "a".
Then, angle (-9x-12) + angle a = 180°
⇒ 105° + a = 180°
⇒ a = 180 - 105
⇒ a = 75°
∴ The measure of angle 5 is 75°

12/16
Step-by-step explanation:
because he 6 in 4/6 cant go into 16 and 16 from 12/16 c 36 so that is why the answer is 12/16
After simplifying each fraction to its lowest terms, it's clear that 12/16, which simplifies to 3/4, is not equivalent to the others since they all simplify to 2/3.
The question asks which of the following fractions is not equivalent to the others: 24/36, 8/12, 12/16, 4/6. To determine this, we need to simplify these fractions to their lowest terms.
24/36 simplifies to 2/3, by dividing both numerator and denominator by 12.
8/12 simplifies to 2/3, by dividing both numerator and denominator by 4.
12/16 simplifies to 3/4, by dividing both numerator and denominator by 4.
4/6 simplifies to 2/3, by dividing both numerator and denominator by 2.
Therefore, the fraction 12/16 is not equivalent to the others since it simplifies to 3/4, while the others simplify to 2/3.

A. (x + 4)
B. 2(x − 4)
C. (x − 4)
D. (x + 4)(x − 4)
The product in simplest form is (x - 4)
Solution:
Given expression is:
[tex]\frac{8}{2x+8} \times \frac{x^2-16}{4}[/tex]
We have to find the product in simplest form
In the given expression,
2x + 8 = 2(x+ 4)
We know that,
[tex]a^2-b^2=(a+b)(a-b)[/tex]
Therefore,
[tex]x^2-16 = x^2-4^2 =(x+4)(x-4)[/tex]
Substitute these in given expression
[tex]\frac{8}{2(x+4)} \times \frac{(x+4)(x-4)}{4}[/tex]
Cancel the common factors,
[tex]\frac{8}{2(x+4)} \times \frac{(x+4)(x-4)}{4} = x - 4[/tex]
Thus the product in simplest form is (x - 4)

First: State the degree and tell which monomial (term) you determined to be the one as the greatest degree. Second: Classify each of the 2 polynomials. If it is NOT a polynomial, explain why you think it is not a polynomial. For example you may say: Polynomial # 4. has degree of 5 and is classified as a quintic polynomial of 4 terms. We covered this in class (see below). Explain in sentences how you determined degree and "name" or why it is NOT a polynomial: 1. 7x4 + 5x2 + x − 92. 7x6 − 4x3 + 1x
Step-by-step explanation:
The relationship between monomial, degree and polynomial
A monomial is basically an individual term. A polynomial is the sum of monomials. Any monomial (term) which contains the highest power of the variable would be considered as the degree of a polynomial. For example, [tex]2x^{2} + 3x + 1[/tex] is a polynomial of degree 3, as the first monomial (term) has the highest power (degree) of the variable x.Now, lets analyze the given algebraic expressions
Examining the first polynomial
Considering the first polynomial
[tex]7x^4\:+\:5x^2\:+\:x\:-\:9[/tex]
Carefully notice that the first term [tex]7x^{4}[/tex] which is also called a monomial does have the highest exponent or power of a variable x, which is 4. Thus, it can be determined that the degree of [tex]7x^4\:+\:5x^2\:+\:x\:-\:9[/tex] will be 4.Here is the summary of the classification of the first polynomial [tex]7x^4\:+\:5x^2\:+\:x\:-\:9[/tex].
[tex]7x^4\:+\:5x^2\:+\:x\:-\:9[/tex] is a polynomial of 4 terms.Its degree is 4.It can also be named as 'quintic' because its degree is 4Examining the second polynomial
Considering the expression
[tex]7x^6\:-\:4x^3\:+\:1/x[/tex]
It is easy to figure out that [tex]7x^6\:-\:4x^3\:+\:1/x[/tex] is not a polynomial as it does not fulfill the criteria to be a polynomial as its last term is [tex]\frac{1}{x}[/tex] has the variable x in the denominator.
Here are some important things that need to be fulfilled for any expression to be a polynomial.
The polynomial can not contain any variable having fractional or negative powers. For example, any expression containing [tex]2v^{-5}[/tex] in any of its terms can not be a polynomial as the variable v has a negative power of exponent. Similarly, the polynomial can not contain any square root of variables. For example, any algebraic expression with the term [tex]2\sqrt{v}[/tex] can not be a polynomial as the variable v is right inside the radical symbol.The polynomial can not have any variable in the denominator. For example, any expression that contains the term [tex]\frac{7}{v}[/tex] would not be treated as the polynomial as the variable v is in the denominator.Therefore, from the above discussion we can safely say that the expression [tex]7x^6\:-\:4x^3\:+\:1/x[/tex] can not be treated as as a Polynomial as its last term [tex]\frac{1}{x}[/tex] contains the variable x which is in the denominator.

solve each inequality, graph the solution, and write the solution in interval notation
5 ≤ 4x− 1 < 7
The compound inequality 5 \u2264 4x - 1 < 7 results in the solution set [1.5, 2) when solved and graphed. In interval notation, it is expressed as [1.5, 2).
Explanation:To solve the compound inequality 5 \<= 4x - 1 < 7, we split it into two separate inequalities and solve them individually:
Add 1 to all parts of the inequality: 6 \<= 4x < 8.Divide all parts by 4:\(\frac{6}{4} \<= x < \frac{8}{4}\).Simplify the fractions:1.5 \<= x < 2.The solution set is the interval [1.5, 2). To graph this solution, plot a closed circle at 1.5 and an open circle at 2, and shade the region in between. In interval notation, the solution set is represented as [1.5, 2).
I need help finding the values of x and z
Answer:
z = 73
x = 15
Step-by-step explanation:
Since z and (5x +32) share a straight line, adding them would equal 180.
(5x+32) + z = 180
Since z is 73, we can replace z
(5x + 32) + 73 = 180
(5x + 32) = 107
(5x) = 75

the cost of producing x laser printers is given by C(x)=325x + 2,300,000. Each printer can be sold for $450
Answer:
C(450)=2,446,250
Step-by-step explanation:
C(450)=325(450)+ 2,300,000
C(450)=146,250+2,300,000
C(450)=2,446,250
The profit from producing and selling x laser printers is given by the equation P(x) = 125x - 2300000.
Explanation:The question is about the calculation of profit in a business scenario. The calculation of profit involves finding the difference between the cost of production and the revenue obtained from selling the products. In this case, the cost function C(x) = 325x + 2300000 defines the cost of producing x laser printers. Each printer is sold for $450, which means the revenue function R(x) can be represented as R(x) = 450x.
To find the profit, we subtract the cost from the revenue. This gives us the profit function P(x) = R(x) - C(x) = 450x - (325x + 2300000). Simplifying this, we get P(x) = 125x - 2300000. This equation tells us the profit made from producing and selling x laser printers.

Jeff bought a bottle of water for $2. He also
bought some hot dogs for $3 each. Jeff did
not spend more than $14 on the hot dogs
and the bottle of water. Write an inequality
statement that can be used to find h, the
number of hot dogs that Jeff could have
bought.
Final answer:
The inequality to determine the number of hot dogs Jeff could have bought is 3h + 2 ≤ 14, representing the cost of hot dogs and the bottle of water not exceeding the total amount of $14.
Explanation:
To find h, the number of hot dogs that Jeff could have bought, we can write an inequality statement based on the maximum amount Jeff can spend and the cost of the hot dogs and water. Jeff bought one bottle of water for $2 and some hot dogs for $3 each. Given that he did not spend more than $14 on everything, the inequality to represent this scenario can be written as:
Cost of water + Cost of hot dogs ≤ Total amount Jeff can spend
2 + 3h ≤ 14
This inequality suggests that when we multiply the number of hot dogs Jeff bought (h) by $3 and add the cost of the water ($2), it should not exceed $14. So the inequality demonstrating the number of hot dogs Jeff could have bought without spending more than $14, including the water, is 3h + 2 ≤ 14.

Given the graph of the function F(x) below, what happens to F(x) when x is a negative number with a large absolute value?
Answer:F(x) is a negative number with a small absolute value
Step-by-step explanation:
The true statement about the graph of f(x) is (a) f(x) is a negative number with a small absolute value
How to interpret the function?From the given graph, we have the following highlights:
As the absolute value of x increases in the positive axis, the value of f(x) decreasesAs the absolute value of x decreases in the negative axis, the value of f(x) decreasesThe above means that, when x is a negative number with a large absolute value, then the absolute value of x is a very large positive number.
And so the value of f(x) would be a small absolute value negative number
Hence, the correct option is (a) f(x) is a negative number with a small absolute value

suppose you flip a coin twice. what is the probability that you get tails on the first flip and tail on the second flip?
Probability of getting tails on the first flip: 1/2 (because it's one of two possible outcomes).
Probability of getting tails on two consecutive flips: 1/4 (because it's one out of four possible outcomes- tails tails, tails heads, heads tails, heads heads)
A simpler way of thinking about it is 1/2*1/2, because you already have 1/2 for getting tails the first time, and if getting tails the second time were an independent event then the probability would be 1/3, but since it's getting tails twice you multiply the probabilities.
Either way, the answer is 1/4 (or 25%)
If you flip a coin twice the probability that you get tails on the first flip and tails on the second flip is 1/4.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that you flip a coin twice, the probability getting tails on the first flip we have to find the probability that you get tails on the first flip and tails on the second flip.
The probability of getting tails on the first flip is
P(T) = 1/2
When two coins get flipped the total possible outcomes are,
(T, H)(T,T)(H,H)(H,T)
Probability of getting tails on two consecutive flips,
P(T) =1/4
The probability that you get tails on the first flip and tails on the second flip
Thus, if you flip a coin twice the probability that you get tails on the first flip and tails on the second flip is 1/4.
