The part of the drawing that shows information about scale, the date of the last revision, and the drawing number is the balloon framing.
Where is a drawing's scale often indicated?
Here, the scale may be shown on the drawing's axes or real distances may be displayed on the axes. In other situations, a scale could employ multiple measuring units. The air velocity, for instance, might be represented by the length of an arrow on an air flow diagram, where 1 cm = 0.1 m/s.What does balloon framing mean?
In contrast to platform framing, where each floor is framed independently, balloon framing uses studs (vertical members) that stretch the entire height of the building (often two storeys) from the foundation plate to the rafter plate.

The point closest to -
the yz-plane is c(2, 9, 3).the xz-plane is a(8, 0, 6).What is a plane in 3-D?A plane is a two-dimensional flat surface that can extend indefinitely. A plane would be the two-dimensional equivalent of a point with zero dimensions, a line with one dimension, and three-dimensional space.
The equation is written on a three-dimensional plane is;ax+by+cz+d=0,
where minimum one number out of a, b, and c must be non-zero.
In 3D coordinate space, a plane is defined by a point and a vector perpendicular to the plane.Now, as per the question;
A point (x, y, zdistance )'s from the yz plane is equal to |x|.
As a result, for small |x|, the point would be closest to the yz plane.
C does have the smallest among A, B, and C that is |x| = 2.
Thus, c point is closest to yz-plane.
If the point is in the xz-plane, after which y equals 0.
Only A has a y value of zero.
As a result, A is in the xz-plane.

A point located on the second hand of a large clock has a radial acceleration of 0.09 cm/s2. how far is the point from the axis of rotation of the second hand?
The distance of point from the axis of rotation of the second hand is 8.2 cm.
Here,
A point located on the second hand of a large clock has a radial acceleration of 0.09 cm/s2.
We have to find the distance of point from the axis of rotation of the second hand.
What is Rotation?
The circular motion of an object around the circle is called Rotation.
Now,
Let us consider the equation for the centripetal acceleration given by;
[tex]a_{c} = \frac{v^{2} }{r}[/tex]
where, v is the velocity and r is the radius.
Now, the velocity can be expressed as;
[tex]v = wr = \frac{2\pi r}{T}[/tex]
where, ω is the angular velocity and T is the period.
Solving for the radius using these equations given as;
[tex]a_{c} = \frac{v^{2} }{r}\\\\v^{2} = a_{c} r\\\\(\frac{2\pi r}{T} )^2 = a_{c} r\\\\\frac{4\pi ^{2}r^{2} }{T^{2} } = a_{c} r\\\\r = \frac{T^{2} a_{c} }{4\pi ^{2} } \\\\r = \frac{(60s)^2(0.09 cm/s^2)}{4\pi ^{2} } \\\\r = 8.2 cm[/tex]

In the figure below, m1= (x+24)° and m2=5x°,
Find the angle measures.
12
Measure of angle 1 is 50° and that of angle 2 is 130°
The sum of all the angles on a straight line is equal to 180°.
Here, we are given two angles ∠1 and ∠2
Also, we are given that
m∠1 = (x+24)°
and m∠2 = 5x°
As we can see from the given figure, ∠1 and ∠2 lie on a straight line
⇒ m∠1 + m∠2 = 180
⇒ (x+24) + 5x = 180
x + 24 + 5x = 180
x + 5x + 24 = 180
6x + 24 = 180
6x = 180 - 24
6x = 156
x = 156/ 6
x = 26
Therefore,
m∠1 = 26 + 24
= 50
and m∠2 = 5(26)
= 130
Thus, the measure of the two angles is 50° and 130°

Testing for within × within and between × within moderation using random intercept cross-lagged panel models "allow measurement decomposition into between- & within components and have thus are becoming famous for testing developmental hypotheses."
What is cross-lagged panel models?Cross lagged panel design is a form of structural equation model in which data is gathered at a number of points in time. It is primarily used to assess causal relationships (which may be bi-directional) in a non-experimental setting, where variables are not controlled but simply recorded.
According to cross-lagged panel design analysis:
If rX1Y2 is'significantly different' from zero, we can draw the conclusion that X is the cause of Y.If rX2Y1 is significantly distinct from zero, we can deduce that Y is the cause of X.If they are both substantially different from zero, we deduce that X causes Y and Y causes X. If they are both equal, we reach the conclusion that they do not cause each other but instead are both affected by a third variable.If we understand that X and Y are correlated but with us data shows no conclusive correlation (neither rX1Y2 or rX2Y1 are significantly different from zero), it is possible that our time lag was just too short (or too long) to enable causal influences to operate, and we need to redesign our experiment.

The irreversible loss of an island from over 100 acres in size to less than 3 acres is an example of?
The irreversible loss of an island from over 100 acres in size to less than 3 acres is an example of the irreversible nature of human change.
Human activity has lead to the change of Earth's climate in unimaginable ways over the last thousand years. Some of these changes are so significant that they are practically inevitable and irreversible.
Due to global warming, the planet's temperature is increasing gradually every year. This change in climate causes polar ice caps to melt and increases the water level.
Islands, which are pieces of land in between water bodies, are reducing in size due to this. The increased water level submerges some or all parts of an island. This is especially threatening for small islands.
This is not only dangerous for the human and wildlife population of these islands, but also for the general habitability. Due to frequent flooding, soil salinity increases and this makes it difficult to cultivate these islands.

A parallelogram with all right angles is known as a rectangle, and a quadrilateral with equal sides is known as a rhombus.The area is always given by squared units and never by single units!

Which table has a constant of proportionality between y and x of 0.3?
Table C has a constant proportionality between y and x of 0.3.
A constant is an expression-unchanging value or number. It always has the same value.
In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one double, and both decrease in size when one drops to a tenth of its original value.
The answer is the same as the one in the y column when you multiply the x number in table C by 0.3. The value that remains constant in the ratio is the proportionality constant. It is evident that table C is accurate because when you multiply each value in the x column by 0.3, the result is always the value in the y column.

The inverse of the function is; f⁻¹(x) = - 15 ± √(x + 225)
What is the Inverse of the Function?We have been given a quadratic function f(x) = x(x + 30) and we need to restrict the domain such that it becomes a one to one function.
Now, the given function can also be written in vertex form as;
f(x) = (x + 15)² - 225
We know that vertex of this quadratic function occurs at (-15, -225).
Further, we know that range of this function is (-225, ∞).
If we restrict the domain of this function to either (-∞, -225) or (-225, ∞) , it will become one to one function.
Let us know find its inverse;
y = (x + 15)² - 225
Upon interchanging x and y, we get:
x = (y + 15)² - 225
Solving for y gives;

The price for us postage stamps has increased over the years. since 1975, the price has increased from $0.13 in 2005 at a rate that is approximately linear. write a linear model for the price of stamps during this time period. let p represent the price and t represent the number of years since 1975.
It is found that Linear Equation: P = 0.008T + 0.13 and Price of stamp in 2015 = $0.45
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
From 1975 to 2005, 30 years, the price increased from 0.13 to 0.37.
This means the rate of change (slope) = 0.24/30 = 0.008
This means Price changed (increased) by $0.008 per year.
Slope = 0.008
The y-intercept (P) is at the starting point which is at T = 1975; the price was 0.13. Hence y-intercept is 0.13
The equation of a line is given as;
P = mT + b
Where m is the slope and b is the y-intercept.
Now, we can write the linear model equation as;
P = 0.008T + 0.13
Then to find the price of stamp in 2015, we see that this is 40 years later after 1975. So we plug in 40 into T in the equation found above;
P = 0.008(40) + 0.13
P = $0.45

Probability of an event E represented by P(E) can be defined as (The number of favorable outcomes )/(Total number of outcomes).
Permutations is defined as arrangement of elements/objects in a particular way.
