R0, 90°
R0, 180°
R0, 270°
R0, 360°
Another way to state the transformation is D. R0, 360°
Calculations and Parameters
Given that the rotation is:
(x,y) --------> (x,y)
This shows that it goes back to its original position and there is a full rotation occurred.
Based on its full rotation to 360°, it can be noted that option D is another way to state the transformation as other given rotations would give different translations.

Simplify (7x+42)/(x^2+13x+42)
The simplified expression is given by:
[tex]\dfrac{7}{x+7}[/tex]
Step-by-step explanation:We are asked to simplify the expression which is given in terms of variable x as:
[tex]=\dfrac{7x+42}{x^2+13x+42}[/tex]
The given expression is a rational expression as it is a polynomial expression in the denominator as well as in the numerator.
Now we know that:
[tex]7x+42=7(x+6)[/tex]
and
[tex]x^2+13x+42=x^2+7x+6x+42\\\\\\i.e.\\\\\\x^2+13x+42=x(x+7)+6(x+7)\\\\\\i.e.\\\\\\x^2+13x+42=(x+7)(x+6)[/tex]
Hence, we get:
[tex]\dfrac{7x+42}{x^2+13x+42}=\dfrac{7(x+6)}{(x+6)(x+7)}\\\\\\i.e.\\\\\\\dfrac{7x+42}{x^2+13x+42}=\dfrac{7}{x+7}[/tex]
Hence, the simplified expression is:

A survey conducted by a song rating service finds that the percentages of listeners familiar with poker face by lady gaga who would give the song ratings of 5, 4, 3, 2, and 1 are, respectively, 50 percent, 18 percent, 19 percent, 8 percent, and 5 percent. assign the numerical values 1, 2, 3, 4, and 5 to the (qualitative) ratings 1, 2, 3, 4, and 5 and find an estimate of the probability distribution of x = this song’s rating by a randomly selected listener who is familiar with the song.
The probability distribution of the song 'Poker Face' ratings by a randomly selected listener familiar with the song can be represented by assigning probabilities to each rating based on the survey percentages. The sum of these probabilities equals 1, confirming a valid distribution.
Explanation:The student is asking about how to find the probability distribution for the ratings given to the song 'Poker Face' by Lady Gaga. To solve this, we assign numerical values to the qualitative ratings: 1, 2, 3, 4, and 5 correspond to the ratings 1 through 5, respectively.
We can list out the probabilities for each rating based on the survey as such:
Rating 5: P(X=5) = 50% or 0.50Rating 4: P(X=4) = 18% or 0.18Rating 3: P(X=3) = 19% or 0.19Rating 2: P(X=2) = 8% or 0.08Rating 1: P(X=1) = 5% or 0.05This list represents the estimation of the probability distribution of a song's rating by a randomly selected listener familiar with the song. In other words, it tells us the likelihood that a listener would rate the song at a certain level.
To confirm this is a valid probability distribution, we must check that the sum of all probabilities adds up to 1:
0.50 + 0.18 + 0.19 + 0.08 + 0.05 = 1.00
Since the sum is equal to 1, we have a valid probability distribution.

EASY 5 POINTS!!! A spherical ball just fits inside a cylindrical can, 16 centimeters tall, with a diameter of 16 centimeters. Which expression gives the volume of the sphere in cubic centimeters?
formula for volume of a sphere is V=4/3 x pi x R63
if diameter = 16 than radius = 16/2 = 8
so the equation would be 4/3 x pi x 8^3
A cylinder storage tank is to contain V=16,000pi cubic feet (about 400,00 gallons). the cost of the tank is proportional to its area, so the minimal-cost tank will be the one with minimum area. The volume (V) of a cylinder of radius r and height h is (pi)(r^2)(h). its surface area is the area of top and bottom, 2(pi)(r^2), plus the side area 2(pi)(r^2)(h). find the dimensions, r and h, of the minimal-area tank

Use spherical coordinates. evaluate (9 − x2 − y2) dv, where h is the solid hemisphere x2 + y2 + z2 ≤ 4, z ≥ 0.
To solve the given task, change the Cartesian coordinates into spherical coordinates. Rewrite the integrand and the solid hemisphere limits according to these new variables. Evaluate the final triple integral using standard techniques.
Explanation:To solve the given problem, the first step is to convert the Cartesian coordinates into spherical coordinates. In spherical coordinates, a point in three dimensions is represented by three parameters: ρ (rho) for the radial distance, θ (theta) for the azimuthal angle, and φ (phi) for the polar angle.
Here, given x² + y² + z² ≤ 4, z ≥ 0, the given region corresponds to a solid hemisphere centered at the origin and radius 2 in spherical coordinates, goes as 0 ≤ ρ ≤ 2, 0 ≤ θ ≤ 2π, and 0 ≤ φ ≤ π/2. Our spherical coordinates are x = ρsin(φ)cos(θ), y = ρsin(φ)sin(θ), and z = ρcos(φ).
Then, rewrite the integrand using spherical coordinates, (9 - x² - y²) becomes (9 - ρ²sin²(φ)) and dv becomes ρ²sin(φ)dρdφdθ.
The final integral that needs to be evaluated will read: ∫₀^2 ∫₀^π/2 ∫₀^2π (9 - ρ²sin²(φ))ρ²sin(φ) dθ dφ dρ. This is a triple integral in spherical coordinates that you can now solve using standard integration techniques.

Professor whata guy surveyed a random sample of 420 statistics students. one of the questions was, "will you take another mathematics class?" the results showed that 252 of the students said yes. what is the sample proportion, p, of students who saud they would take another math class?
The sample proportion, p, of students who said they would take another math class, p = 0.6 or 60%.
To determine the sample proportion, p, you can use the following formula:
p = x/nwhere:
x is the number of students who said yes (successes).n is the total number of students surveyed.From the question,
x = 252n = 420Substituting these values into the formula gives:
p = 252 / 420 = 0.6
Therefore, the sample proportion of students who said they would take another math class is 0.6 or 60%.
Find m2, if m6 = 57° and m7 = 23°.
Final answer:
To find m2, subtract m6 from 180 degrees.
Explanation:
To find m2 in this problem, we can use the fact that angles in a triangle sum up to 180 degrees. We know that m6 = 57° and m7 = 23°.
First, we can find m1 by subtracting m7 from 180 degrees: m1 = 180° - 23° = 157°.
Next, we can find m2 by subtracting m6 from 180 degrees: m2 = 180° - 57° = 123°. Therefore, m2 is equal to 123 degrees.
