find the volume of the parallelepiped with adjacent edges pq, pr, and ps. p(−2, 1, 0), q(3, 4, 3), r(1, 4, −1), s(3, 6, 4)
The volume of the Parallelepiped with adjacent edges pq, pr,and ps = 136
Geometrically, the Scalar triple product:
[tex]{\displaystyle \mathbf {a} \cdot (\mathbf {b} \times \mathbf {c} )} \mathbf{a}\cdot(\mathbf{b}\times \mathbf{c})[/tex]
is the (signed) volume of the parallelepiped defined by the three vectors given. Here, the parentheses may be omitted without causing ambiguity, since the dot product cannot be evaluated first. If it were, it would leave the cross product of a scalar and a vector, which is not defined.
Given three vectors, there is a product, called scalar triple product, that gives , the volume of the parallelepiped that has the three vectors as dimensions.
So,
Given : p(-2,1,0) , q(3,4,3), r(1,4,-1), s(3,6,4).
pq = ( -2-3 ,1-4 ,0-3) = (-5,-3,-3)
pr= (-2-1, 1-4, 0+1) = (-3,-3,1)
ps= ( -2-3, 1-6, 0-4) = (-5,-5,-4)
pq = (-5 , -3 , -3)
pr = (-3, -3, 1)
ps= (-5, -5, -4)
The scalar triple product is given by the determinant of the matrix (3×3)
that has in the rows the three components of the three vectors:

Anais bought 2 1/2 yards of ribbon. She had 2 feet 8 inches of ribbon left after trimming some curtains. Anais uses 58 inches of ribbon to trim the curtains.
Given that:
Anais bought of ribbon
And she had 2 feet 8 inches left after trimming some curtains.
The first thing to do is to convert all units to inches;
From standard conversion rate.
1 yard = 36 inches
As such of ribbon in inches will be:
= 5 × 18 inches
= 90 inches of ribbon bought.
Similarly, since 1 foot = 12 inches.
The amount of curtains left after trimming is:
= ( ( 2 × 12 ) + 8 )inches
= (24 + 8) inches
= 32 inches
If Anais bought 90 inches of ribbon and she had 32 inches of ribbon left after trimming some curtains.
It implies that the number of inches of ribbon that Anais used is:
= 90 inches - 32 inches
= 58 inches

Applying the tangent ratio, the length of side x, in simplest radical form is: 8√3.
How to Apply the Tangent Ratio?The tangent ratio is: tan ∅ = opposite side length / adjacent side length of the right triangle.
Given the following:
Reference angle (∅) = 30 degrees.
Opposite side length = 8
Adjacent side length = x = ?
Using the tangent ratio, we have: tan 30 = 8/x
x(tan 30) = 8
Divide both sides by tan 30
x(tan 30)/tan 30 = 8/tan 30
x = 8/tan 30
x = 8/1/√3
x = 8 × √3
x = 8√3

The side lengths of RS and PR are 12 units
What are similar triangles?Similar triangles are triangles whose corresponding sides are in proportion to one another.
In most cases, one triangle is dilated to form the other triangle
What is dilation?Dilation involves enlarging or reducing the side length of a shape to create another shape by a constant scale factor, where the scale factor does not equal one.
How to determine the side length of PR?The corresponding triangles are given as:
PQR and PSQ
This means that
PQ corresponds to PS
PR corresponds to PQ
QR corresponds to QS

Applying the exterior angle theorem, the value of s in the triangle is: 74.
How to Apply the Exterior Angle Theorem?In the image shown above, the angles, s - 44° and s° are interior opposite angles to the exterior angle of the triangle that is given as s + 30°.
Based on the exterior angle theorem, the sum of s - 44° and s° is equal to s + 30°.
Therefore:
s - 44 + s = s + 30 [exterior angle theorem]
Combine like terms
2s - 44 = s + 30
2s - 44 - s = s + 30 - s [subtraction property of equality]
s - 44 = 30

given values of median, mean, mode, first and third quartiles for the observations of a numeric feature, what insights can we gain into the statistical distribution of its observations?
Median, mean, mode, first and third quartiles describe a statistical distribution because these are the measures of central tendency and dispersion of a distribution.
Median, mode and mean are known as the measures of central tendency of a statistical distribution. Because these three can even represent the whole data and its properties. Mean, median and mode gives the central value around which the whole distribution lies or its representative value.
Mean: It gives the average value of the distribution. That is the Total value/ Total number of values.
Median: It is a positional average and it is the middle value of the observations in a distribution.
Mode: Mode is also a positional average which gives the most repeated or frequent observation from the distribution
Now the first and third quartiles are measures of dispersion. It gives the variation of data values from the central value. It gives an idea of the scattering of the distribution around the central value.
First quartile: If the n observations are arranged in ascending order, then the n/4th value is the first quartile.
Third Quartile: It is the 3n/4th value in the ordered n observations.
These two are used to measure the quartile deviation from the central value. If the dispersion is large, then the measures of central tendency cannot be a representative value of the distribution.

A scale factor of 2 would be the perfect scale for the scale drawing.
How to interpret Scale Drawing?We are given original dimensions of tech fingerboard as;
Length = 100 mm
Width = 25 mm
Now, from conversions we know that;
1 inch = 25.4 mm
Since Giovanni wants to make a larger scale drawing on an 8 1/2 inch by 11-inch piece of paper, then we can say that;
11-inch = 25.4 * 11 = 279.4 mm
8 1/2 inch = 8 1/2 * 25.4 = 215.9 mm
Thus;
New Length/old length = 279.4/100 = 2.794
Since that is the maximum scale for the drawing paper, then we can say that something lesser like a scale factor of 2 would be the perfect scale for the scale drawing.

Answer: k(8z - 2)=448z^2-224z+35
z(q^2)=-10q^4 - 5
Step-by-step explanation:
k(z) = 7z^2 + 7
k(8z - 2)=7(8z - 2)^2 + 7
k(8z - 2)=7(8z - 2)(8z - 2) + 7
k(8z - 2)=7(64z^2-16z-16z+4) + 7
k(8z - 2)=7(64z^2-32z+4) + 7
k(8z - 2)=7(64z^2-32z+4+1) ==> 7*1=7, so +1 is added in parentheses while +7 is removed outside of parentheses.
k(8z - 2)=7(64z^2-32z+5)
k(8z - 2)=448z^2-224z+35
z(q) = -10q^2 - 5
z(q^2)=-10(q^2)^2 - 5
z(q^2)=-10(q^(2*2)) - 5
z(q^2)=-10q^4 - 5
Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
The slope of the line in the given graph = rise/run = 3.
How to Find the Slope of a Line?To determine the value of the slope of a line on a coordinate plane, we can find the ratio of the rise of the line to that of its run. This means that, the formula for calculating the slope of a line would be:
Slope = rise/run.
Vertical distance across the line is the rise of the line
Horizontal distance across the line is the run of the line
In the graph given, we have:
The rise is labelled as the blue line = 9 units
The run is labelled as the red line = 3 units
Slope of the line (m) = 9 units/3 units
Slope (m) of the given line = 9/3 = 3
Therefore, the slope of the line in the given graph = rise/run = 3.
