MZYX=pi/3 radians. Covert this radian measure to its equivalent degree measure.
60°
120°
180°
300°
MZYX=pi/3 radians is equivalent to 60 degrees. To convert radians to degrees, we use the formula: degree measure = (radian measure) x (180/π)
So, to convert MZYX=pi/3 radians to degrees, we plug in the value:
degree measure = (pi/3) x (180/π)
The π in the numerator and denominator cancel out, leaving:
degree measure = (1/3) x 180
Simplifying, we get:
degree measure = 60
Therefore, MZYX=pi/3 radians is equivalent to 60 degrees.
It's important to understand the concept of radians and degrees when dealing with angles. Radians are a unit of measure for angles, just like degrees. However, while degrees divide a circle into 360 equal parts, radians divide a circle into 2π equal parts. One radian is the angle formed at the center of a circle when the length of the arc on the circumference is equal to the radius of the circle.
In summary, to convert radians to degrees, we use the formula: degree measure = (radian measure) x (180/π). We can use this formula to convert any angle given in radians to its equivalent measure in degrees.

Explanation:
Plug in x = 3 to find that f(x) = 3/x outputs f(x) = 1
This shows (x,y) = (3,1) is on the function curve. This means the curve has some portion of it in the upper right quadrant.
This narrows the answer choices between B and D.
Now try x = -3 to find that f(-3) = -1
So (-3,-1) is another point on the curve.
This rules out choice D, and means choice B is the final answer.
Use something like a TI83/84, Desmos, or GeoGebra to verify the answer.

what are the si units of the proportionality constant g?
The SI units of the proportionality constant G is Newton \(Kg^{-2} m^2\)
Gravitational force is given by Newton's law of gravitation which states that every particle of matter in the cosmos is drawn to every other particle by a force of attraction that varies directly with the product of their masses and is inversely proportional to the square of the distance or degree of separation from each other.
F = G \($ \frac{m_1 m_2}{r^2}\)
Upon rearranging the terms we get,
G = \($\frac{F r^2}{m_1 m_2}\)
Where F is the gravitational force, \(m_{1}\) and \(m_{2}\) are masses, and r is the length.
Force has the SI units kg · m/s2
The SI units of the proportionality constant G
SI Unit of G = \($\frac{(\text { Newton })\left(\mathrm{m}^2\right)}{\mathrm{kg} ^2}\)

For given triangle, the value of x =5/6.
What is a triangle's definition?
A triangle is a geometric shape that consists of three straight line segments that connect to form a closed shape. It is a polygon with three sides, three vertices (corners), and three angles. Triangles can have different shapes and sizes depending on the length of their sides and the measure of their angles.
The sum of the interior angles of a triangle is always 180 degrees. This means that the three angles of a triangle add up to 180 degrees. The size and shape of the angles can vary, however, depending on the lengths of the sides.
Now,
For given triangle
as ∠CAE=∠BAE
then,

The concept is the Vertical Lines. The Vertical Lines are a pair of opposing, congruent angles created by intersecting lines. It is option A.
An upward line is a line on the direction plane where every one of the focuses on the line have a similar x-coordinate. Because they are perpendicular to the ground and extend toward the sky, vertical lines frequently convey a sense of height.
At the point when two straight lines cross each other vertical points are shaped. Every vertical angle is equal and congruent.
By super-imposing the two pairs of non-adjacent angles created by intersecting two lines, vertical angles are congruent.
Every vertical angle has the same length. We call angles congruent when their measurements are the same.

If you vertically compress the exponential parent function f(x)=2^x by a factor of 3
Vertically compressing the exponential parent function f(x) = 2^x by a factor of 3 means multiplying every function value by 1/3, resulting in a steeper and narrower curve closer to the x-axis.
If we vertically compress the exponential parent function f(x) = 2^x by a factor of 3, it means that every point on the graph of the function will be compressed closer to the x-axis. In other words, the function values will be multiplied by 1/3.
Let's consider a point on the original exponential function, (x, f(x)). After the vertical compression, this point will have the coordinates (x, (1/3)f(x)). For example, if f(x) = 8 for some x, after compression, the corresponding point will be (x, (1/3)(8)) = (x, 8/3).
This vertical compression affects all points on the graph uniformly, resulting in a steeper and narrower curve compared to the original exponential function.
The y-values of the compressed function will be one-third of the y-values of the original function for each x-value. Therefore, the graph will be squeezed vertically, with the y-values closer to the x-axis.

change from rectangular to cylindrical coordinates. (let r ≥ 0 and 0 ≤ ≤ 2.) (a) (−1, 1, 1) (b) (−6, 6sqrt(3),4)
The cylindrical coordinates for (-6, 6sqrt(3), 4) are (r, θ, z) = (12, -π/3, 4).
To change from rectangular to cylindrical coordinates, we use the following equations:
\(r = \sqrt\(x^2 + y^2)\)
θ = arctan(y/x)
z = z
For part (a), we have the point (-1, 1, 1).
\(r = \sqrt\((-1)^2 + 1^2) }= \sqrt2\)
θ = arctan(1/(-1)) = -π/4 (Note: We use the quadrant in which x and y are located to determine the sign of θ)
z = 1
So the cylindrical coordinates for (-1, 1, 1) are (r, θ, z) = (√2, -π/4, 1).
For part (b), we have the point\((-6, 6\sqrt\((3)}, 4)\).
\(r = √((-6)^2 + (6\sqrt\((3)}}^2) = 12\)
θ = arctan\(((6\sqrt\((3)})/(-6))\) = -π/3 (-6, 6\sqrt\((3)}, 4)
z = 4

In a recent election, 63% of all registered voters participated in voting. In a survey of 275 retired voters, 162 participated in voting. Which is higher, the population proportion who participated or the sample proportion from this survey?
The population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).
To determine whether the population proportion who participated in voting or the sample proportion from the survey is higher, we need to compare the percentages.
The population proportion who participated in voting is given as 63% of all registered voters.
This means that out of every 100 registered voters, 63 participated in voting.
In the survey of retired voters, 162 out of 275 participants voted. To calculate the sample proportion, we divide the number of retired voters who participated (162) by the total number of retired voters in the sample (275) and multiply by 100 to get a percentage.
Sample proportion = (162 / 275) \(\times\) 100 ≈ 58.91%, .
Comparing the population proportion (63%) with the sample proportion (58.91%), we can see that the population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).
Therefore, based on the given data, the population proportion who participated in voting is higher than the sample proportion from this survey.
It's important to note that the sample proportion is an estimate based on the surveyed retired voters and may not perfectly represent the entire population of registered voters.

walks 430 feet per minute.
Answer:
If youre asking how long it will take for Yoshi to catch up look below
Step-by-step explanation:
Yoshi walk 80 feet per minute faster than Trisha
If Trisha walks for 5 minutes she would have walked 2250 feet
If Yoshi also walks for 5 minutes he would have walked 2150 feet
Now this is already pretty close so lets check for 7 minutes
If Trisha walks 7 minutes she would have walked 2950 feet
if Yoshi walks 7 minutes he would have walked he would have walked 3010 feet
Now this is really close but now yoshi is ahead.. so lets go down to 6.85 feet
If Yoshi walks 6.85 minutes he would have walked 2945.5 feet
this is still a LITTLE to low so lets do 6.86
If yoshi walks 6.86 minutes he would have walked 2949.8
Rounding up he would have caught up by now
so it would take Yoshi 6.86 minutes to catch up

Neil reads equal numbers of pages of a book every week. The graph shows the number of pages of the book left to read, y, after x weeks: A graph titled Neil’s Book Reading shows Number of Weeks on the x-axis and Number of Pages Left on the y-axis. The scale on the x-axis shows numbers from 0 to 5 at increments of 1, and the scale on the y-axis shows numbers from 0 to 315 at increments of 45. A straight line joins the ordered pairs 0, 225 and 1, 180 and 2, 135 and 3, 90 and 4, 45 and 5, 0. Which equation best models the relationship between x and y?
y = −5x + 45
y = −45x + 315
y = −5x + 225
y = −45x + 225
Step-by-step explanation:
For every increment of 1 across the x-axis,
the line decreases by 45 units.
Hence the slope is
Rise / Run = (-45)/1 = -45.
The point (0, 225) tells us that the
y-intercept is 225.
y = mx + c, where m is the line's slope and c is the y-intercept.
Hence we have y = -45x + 225.
what is the value of the storativity if the aquifer matrix is incompressible (i.e., rigid and nondeformable)
The value of the storativity for an aquifer with an incompressible (i.e., rigid and nondeformable) matrix is equal to the specific yield. This is because storativity is a measure of the amount of water that an aquifer can store or release in response to changes in hydraulic head. If the matrix is incompressible, the only water that can be stored or released is from the pore spaces within the matrix, which is represented by the specific yield. Therefore, the storativity for an incompressible matrix is equal to the specific yield.
