A scale factor of 2 would be the perfect scale for the 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.

The value of the division (6×1011)÷(3×1015) is the negative 4 power 2×10.

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Division can be interpreted as an equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus,  [tex]a \div b[/tex] = a divided in b equal parts.

WE have been given that (6×10^11)÷(3×10^15) .

Simplify;

(6×10^11)÷(3×10^15)

To solve the exponent first;

10^11 - 15 = 10^-4

Now we get;

(6 )÷(3×10^-4)

2 ×10^4 = 2 ×10 ×10×10×10

= 20,000

Hence, the value of the division (6×1011)÷(3×1015) is the negative 4 power 2×10.

The domain of the function f (x) = x2 + 6x + 5 over the function g(x) = x3 + x2 − 4x − 4 is {x ∈ ℝ| x ≠ −1, −2, 2}.

The main limiting issue with the domain this function is potentially picking an x-value that makes that denominator equal 0, because dividing by 0 is bad.

So, the domain will be all real numbers, except for those that make g(x)=0.

g(-1) = 0, g(-2)=0, and g(2) = 0, so -1, -2, and 2 must be excluded from the domain.

Your answer is {x ∈ ℝ| x ≠ −1, −2, 2}.

Therefore, we get that, the domain of the function f (x) = x2 + 6x + 5 over the function g(x) = x3 + x2 − 4x − 4 is {x ∈ ℝ| x ≠ −1, −2, 2}.

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).

Applying the exterior angle theorem, the value of s in the triangle is: 74.

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

s - 44 + 44 = 30 + 44 [addition property of equality]

s = 74

Therefore, applying the exterior angle theorem, the value of s in the triangle is: 74.

The sequence is in geometric series. Common ration= - 1/2, missing number i.e., the 5th term = 4

An arithmetic series is one where each term is equal to the one before it plus some number. Whereas a geometric series is one where each term equals the one before it multiplied by a certain value.

Here the sequence is Geometric series as from the sequence we are getting the common ratio.

Common ratio = [tex]\frac{-32}{64}[/tex] = [tex]\frac{16}{-32}[/tex] = -[tex]\frac{1}{2}[/tex]

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.

The domain of a function is the set that contains all possible output values for a function. In a graph, it is the set that contains the values of y for which the function is defined.

Looking at the graph, we get that a function f(x) is decreasing when it is "moving northeast", that is, to the right and up on the graph, meaning that when x increases, y decreases.

Using composition formula we get the value of x is 9/16 for G(H(X)) = 32x - 18

In mathematics, composing a function is the process by which two functions, f and g, produce a new function, h, such that h(x) = g(f(x)). This indicates that the function of g is being applied to the function of x. In essence, a function is then applied to the outcome of another function.

We F (2x-18) and G (4x)

By using the composition formula

H(x) = g(f(x))

That is

H(x) = g(2x-18)

      = 2(4x) - 18

      = 8x - 18

If H(x) = 8x - 18

Then, G(H(x))

⇒ G(8x - 18)

⇒ 8(4x) - 18

⇒ 32x - 18

Now, we find x in G(H(x))

The side lengths of RS and PR are 12 units

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

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.

The corresponding triangles are given as:

PQR and PSQ

This means that

PQ corresponds to PS

PR corresponds to PQ

QR corresponds to QS

Where

PQ = 18

QR = 14

QS = 21

So, we have:

PR : QR = PQ : QS

This gives

PR : 14 = 18 : 21

Express as fraction

PR / 14 = 18 / 21

Multiply through by 14

PR = 14 * 18 / 21

Evaluate

PR = 12
