round your answer to the nearest tenth.
23 degrees is the measure of the indicated angle in the triangle.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The given triangle is a right angled triangle.
The side lengths of triangle are 35 and 38.
We have to find the measure of the angle opposite to the right angle.
By using cosine function formula we calculate it.
CosA=Adjacent side/Hypotenuse
CosA=35/38
m∠A=cos⁻¹(35/38)
= 22.91954215
Hence, 23 degrees is the measure of the indicated angle.

Freud is not a stage theorist
Freud is a stage theorist
Freud is a stage theorist. Sigmund Freud, the renowned Austrian neurologist and psychoanalyst, is widely recognized as one of the pioneers in the field of psychoanalysis.
He proposed a developmental theory that included psychosexual stages of development. According to Freud, human development progresses through distinct stages, each characterized by a specific focus on different erogenous zones. These stages include the oral stage, stage, phallic stage, latency stage, and genital stage. Freud believed that the way individuals navigate these stages influences their personality and psychological well-being in adulthood.
Although Freud's stage theory has been critiqued and modified over time, his ideas regarding the importance of early childhood experiences and unconscious processes have had a profound impact on psychology and continue to shape our understanding of human development.

y=-4(x-2)^2+6? Solve foil
The solutions for the equation \(y=-4(x-2)^2+6\) are as follows \(x = 2 + \sqrt{(6 - Y) / 4}\) or \(x = 2 - \sqrt{(6 - Y) / 4}\).
The given equation is in standard form for a quadratic equation, where the coefficient of \(x^2\) is negative. This means the graph of the equation is a downward-opening parabola, and the vertex of the parabola is (2, 6).
To solve the equation, we can first isolate the variable Y on one side:
\(Y - 6 = -4(x - 2)^2\)
Then we can divide both sides by -4:
\((Y - 6) / -4 = (x - 2)^2\)
Next, we can take the square root of both sides:
\(\sqrt{[(Y - 6) / -4] }= x - 2\)
\(\pm \sqrt{(Y - 6) / -4}= x - 2\)
So the solutions are:
\(x = 2 + \sqrt{(6 - Y) / 4}\) or \(x = 2 - \sqrt{(6 - Y) / 4}\)
These equations give the x-coordinates of the points on the graph of the equation for a given value of Y.

Use Newton's method with initial approximation
x1 = −2
to find x2, the second approximation to the root of the equation
x3 + x + 6 = 0.
x2 = -2.0000. In this way, we get x2, the second approximation to the root of the equation using Newton's method with an initial approximation x1 = −2.
Newton's method is one of the numerical methods used to estimate the root of a function.
The following are the steps for using Newton's method:
Let the equation f (x) = 0 be given with an initial guess x1, and let f′(x) be the derivative of f(x).
Determine the next estimate, x2, by using the formula x2 = x1 - f (x1) / f'(x1).
Therefore, the given equation is x³ + x + 6 = 0.
Let us use Newton's method to solve the given equation. We have x1 = -2, which is the initial approximation.
Therefore, f(x) = x³ + x + 6, and f'(x) = 3x² + 1.
To find x2, the second approximation to the root of the equation, we need to substitute the values of f(x), f'(x), and x1 into the formula x2 = x1 - f (x1) / f'(x1).
Substituting the given values in the above equation we get, x2 = x1 - f (x1) / f'(x1) = -2 - (-2³ - 2 + 6) / (3(-2²) + 1) = -2 - (-8 - 2 + 6) / (3(4) + 1) = -2 - (-4) / 13 = -2 + 4 / 13 = -26 / 13

The Pythagorean theorem applies to right-angled triangles and states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Mathematically, we can express this as:

29÷1334 long division I need to show my work
Answer: 46
Hope this helps
The result of dividing 1334 by 29 is 46 with no remainder.
The long division work for the division problem 29 ÷ 1334:
46
___________
29 | 1334
- 116
_______
174
174
______
0
Start by dividing the leftmost digit of the dividend (1) by the divisor (29). Since 1 is smaller than 29, you bring down the next digit (3) to the right of 1, making the new dividend 13.
Next, divide 13 by 29. The quotient is 0, so you bring down the next digit (4) to the right of 13, making the new dividend 134.
Now, divide 134 by 29. The quotient is 4 (29 × 4 = 116), so you write down 4 above the line.
Multiply 29 by 4 and subtract the result (116) from 134, giving you a new remainder of 18.
Finally, divide 18 by 29. The quotient is 0, so you bring down the next digit (4) to the right of 18, making the new dividend 184.
Since the dividend is smaller than the divisor, you can't divide further.
Therefore, the final quotient is 46, and the remainder is 0.
So, 1334 ÷ 29 = 45 with no remainder.

The value of y in each case are 18,8 and 4 respectively.
Given equation:-
y = -x + 9
Values of x = {-9, 1, 5}
We have to find the corresponding values of y for each value of x.
Putting x = -9 in the given equation, we get,
y = -(-9) + 9 = 9 + 9 = 18
Putting x = 1 in the given equation, we get,
y = -1 + 9 = 8
Putting x = 5 in the given equation, we get,

We have a Random variables X denotes the number of puzzles complete by random choosen subject. The above table contains probability distribution of random variable X. The expected number of puzzles in the 5-minutes period while listening to smoothing music is calculated by following formula, \(E(x) = \sum x_i p(x_i)\)

On average, Nathaniel drinks 4/5
of a 10-ounce glass of water in 2 2/5 hours. How many glasses of water does he drink in one hour? Enter your answer as a whole number, proper fraction, or mixed number in simplest form.
The glasses of water he drinks in one hour is 1/3 of a 10-ounce glass water
How to determine the glasses of water he drinks in one hour?From the question, we have the following parameters that can be used in our computation:
Amount of water = 4/5 of a 10-ounce glass water
Time to drink this water = 2 2/5 hours
To calculate the amount he drank in one hour, we make use of the following equation
Amount of water = Amount of water/Time to drink this water
Substitute the known values in the above equation, so, we have the following representation
Amount of water = (4/5)/(2 2/5)
Evaluate the quotient
Amount of water = 1/3
Hence, the amount is 1/3 of a 10-ounce glass water
