Step-by-step explanation:

The line we want is given by the vector equation

L(t) = (4i + 3j - k) t + (5i + 2.5j + 3.1k)

L(t) = (4t + 5) i + (3t + 2.5) j + (-t + 3.1) k

As parametric equations, we write

x(t) = 4t + 5

y(t) = 3t + 2.5

z(t) = -t + 3.1

The following strings are propositional formulas under the signature:

(i)both 0-place connectives are formulas

(ii)for any binary connective ⨀, if f and g are formulas then (f⊙g) is a formula.

A propositional formula is a particular kind of syntactic formula that is well-formed and has a truth value in propositional logic. A propositional formula yields a distinct truth value when all of the variables' values are known. A propositional formula may alternatively be referred to as a phrase, a propositional expression, or a sentential formula.

Simple statements like "five is greater than three" or propositional variables like p and q are combined to build a propositional formula using connectives or logical operators like NOT, AND, OR, or IMPLIES.

The term "proposition" is frequently used in mathematics to refer to a propositional formula, but in reality, a propositional formula is a formal expression that signifies a proposition.

Solving all the linear equation The value of CD is 6.

An algebraic equation known as a linear equation has terms that are either constants or variables raised to the first power. Alternatively put, none of the exponents can be greater than 1. As an illustration, while x is a variable raised to the first power, x2 is a variable raised to the second power. An illustration of a constant is 5.

Now According to the question

BC = x+1

CD = 14x - 10

BD = 6

by this we can say that

BC + CD = BD

no by substitution method putting values of BC , CD and BD

(x + 1) + (14x - 10) = 6

15x - 9 =6

15x = 15

x = 1

now again by substitution method putting value of x in to 14x-10 we get

CD = 14(1)-10

CD = 4

Hence the value of CD = 4

Divide 0.01 by 2 and u would get 0.005

[tex]r = \frac{u_{4}}{u_{3}} = \frac{ - 56}{28} = - 2[/tex]

a. The common ratio is -2.

b. The first term is 7

c. The sum of the GP is -147

(a) To find the common ratio (r), we can use the formula for the nth term of a geometric progression (G.P):

[tex]A_n = A_1 * r^(^n^-^1^)[/tex],

where Aₙ is the nth term, A₁ is the first term, r is the common ratio, and n is the term number.

Given that the 3rd term (A₃) is 28 and the 4th term (A₄) is -56, we can set up two equations using the formula above:

[tex]28 = A_1 * r^(^3^-^1^)[/tex],     (Equation 1)

[tex]-56 = A_1 * r^(^4^-^1^)[/tex].     (Equation 2)

Dividing Equation 2 by Equation 1, we get:

[tex]-56/28 = (A_1 * r^(^4^-^1^)^) / (A_1 * r^(^3^-^1^))\\-2 = r.[/tex]

Therefore, the common ratio (r) is -2.

(b) To find the first term (A1), we can substitute the known values into one of the equations. Let's use Equation 1:

[tex]28 = A_1 * (-2)^(^3^-^1^)\\28 = A_1 * (-2)^2\\28 = A_1 * 4\\A_1 = 7[/tex]

Therefore, the first term (A₁) is 7.

(c) To find the sum of the geometric progression, we can use the formula for the sum of the first n terms of a geometric progression:

[tex]S_n = (A_1 * (1 - r^n)) / (1 - r)[/tex],

where Sₙ is the sum of the first n terms.

Given that there are 6 terms (n = 6), A₁ = 7, and r = -2, we can calculate the sum (S₆):

[tex]S_6 = (7 * (1 - (-2)^6)) / (1 - (-2)).[/tex]

Simplifying:

S₆= (7 * (1 - 64)) / (1 + 2),

S₆ = (7 * (-63)) / 3,

S₆ = -147.

Therefore, the sum of the geometric progression is -147.

The scalar product between two vectors involves the cosine function of the angle between the lines of action of the two vectors.

The dot product, also known as the scalar product, is an algebraic operation that takes two sequences of numbers of equal length (often coordinate vectors) and outputs a single number. The dot product of two vectors' Cartesian coordinates is frequently used in Euclidean geometry. Although other inner products can be defined in Euclidean space, it is frequently referred to as the inner product (or, less frequently, projection product) of Euclidean space (see Inner product space for more). The sum of the products of the matching entries of the two number sequences is the dot product, according to algebra. Geometrically, it is the result of adding the cosine of the angle between the two vectors and the Euclidean magnitudes of the two vectors.

The ability to reverse other functions makes a function an inverse function. It is somewhat similar to undoing another function, which returns you to your starting point. Driving from home to the shop is a function, and driving from the shop back to home is a function.

The inverse of a trigonometric function, the inverse of a rational function, the inverse of a hyperbolic function, and the inverse of a log function are just a few examples of the various types of inverse functions.

Substituting f(x) with y

f(x)=1/9x+2

y=1/9x+2

x=1/9y+2

For x = 3 and y = 5

[tex]y = x^{2} -1[/tex]

We can substitute x = 3 and y = 5 values,
