The simplified radical expression for this problem is given by:
[tex]3x^2y^3z\sqrt[3]{3xz^2}[/tex]
How to simplify the given radical expression?To simplify the given radical expression, we divide all the exponents by 3, and the ones that can be simplified are placed outside the root, multiplying.
Looking at each term, we have that:
81 is equivalent to 3^4, hence [tex]\sqrt[3]{81} = \sqrt[3]{3^4} = 3\sqrt[3]{3}[/tex], as 4 divided by 3 has quotient 1 and remainder 1.For x^7, we have that 7 divided by 3 has quotient 2 and remainder 1, hence [tex]\sqrt[3]{x^7} = x^2\sqrt[3]{x}[/tex].For y^9, we have that 9 divided by 3 has quotient 3, hence [tex]\sqrt[3]{y^9} = y^3[/tex]For z^5, we have that 5 divided by 3 has quotient 1 and remainder 2, hence [tex]\sqrt[3]{z^5} = z\sqrt[3]{z^2}[/tex].Thus, the simplified radical is given by:
[tex]3 \times \sqrt[3]{3} \times x^2 \times \sqrt[3]{x} \times y^3 \times z \times \sqrt[3]{z^2}[/tex]
[tex]3x^2y^3z\sqrt[3]{3xz^2}[/tex]

Given the endpoints of the diameter, the length of the diameter of the circle P is 20.0.
What is the length of the diameter of the circle?The distance formula used to determine the distance between two points is expressed as;
D = √( (x₂ - x₁)² + (y₂ - y₁)² )
Given the data in the question;
Point 1: (5, -5)
x₁ = 5y₁ = -5Point 2: (-7, 11)
x₂ = -7y₂ = 11Plug the given values into the distance formula and simplify.

Step-by-step explanation:
the divisibility rule of 9 says that if the sum of the numbers of the number you are going to divide by 9 is a multiple of 9 then it is divisible by nine.
1+1+2+2+8+3=17 which is not a multiple of 9.
Therefore it is not divisible by 9.
find a vector equation and parametric equations for the line. (use the parameter t.) the line through the point (5, 2.5, 3.1) and parallel to the vector 4i 3j − k

What is the inverse of the function f(x)=1/9x+2
The correct answer is 9x-18.
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
x-2=1/9y
y=9x-18
Thus inverse is f^-1(x)=9x-18

the scalar product between two vectors involves which function of the angle between the lines of action of the two vectors
The scalar product between two vectors involves the cosine function of the angle between the lines of action of the two vectors.
What is the scalar product?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.

a. The common ratio is -2.
b. The first term is 7
c. The sum of the GP is -147
What is the common ratio?
(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.

If BC = x + 1, CD = 14x − 10, and BD = 6, what is CD? x + 1 B 14x − 10 C D 6 Simplify your answer and write it as a proper fraction, mixed number, or integer.\
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
