Answer:
[tex]4.6\ \text{cm}[/tex]
Step-by-step explanation:
Perimeter of the pentagon = 20.5 cm
Length of 4 sides = [tex]x[/tex]
Length of the other side = 2.1 cm
Perimeter of the pentagon will be
[tex]x+x+x+x+2.1=20.5\\\Rightarrow 4x+2.1=20.5\\\Rightarrow 4x=20.5-2.1\\\Rightarrow 4x=18.4\\\Rightarrow x=\dfrac{18.4}{4}\\\Rightarrow x=4.6\ \text{cm}[/tex]
The value of [tex]x[/tex] is [tex]4.6\ \text{cm}[/tex].

what kind of lines are shown in the picture below?
Answers:
A. Parallel
B.intersecting
C. Skew
D.perpendicular
Answer:
B. Intersecting
Step-by-step explanation:
If you were to extend the lines, they would cross eachother
The given lines are intersecting.
What are intersecting lines?When two or more lines cross each other in a plane, they are called intersecting lines. The intersecting lines share a common point, which exists on all the intersecting lines, and is called the point of intersection.
As, from the figure we can see that the line p and q are not parallel to each other because the distance between them is not constant.
Now, the lines are not either skew or perpendicular.
If we extend the lines p and q then will meet at some point which is know as intersecting lines.

Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 3 and the Trailing Constant is -2.
The factor(s) are:
of the Leading Coefficient : 1,3
of the Trailing Constant : 1 ,2

The graph of the function
m(x) = x^3 + 3x^2 - 2x - 4
has a zero at -1. What are the
other zeros of the function?
Answer: -1 + or - root5
Step-by-step explanation:
The other zeros of function m(x) = x^3 + 3x^2 - 2x - 4 are x = 2, x = -2
Zero of a function:To find the zero of a function f(x), we need to find the value of f(0).
What is trinomial?"A trinomial is a polynomial consisting of three terms."
For given question,
Given function : m(x) = x^(3) + 3x^(2) - 2x - 4
We need to find the zeros of a function.
to find the value of x for which m(x) = 0
x^(3) + 3x^(2) - 2x - 4 = 0
We know, x = -1 is a zero of given function.
So, (x + 1) is the factor of given trinomial x^(3) + 3x^(2) - 2x - 4 = 0.
To factorize above trinomial we divide it by x + 1.
Using synthetic division,
m(x)/(x + 1)
= (x^(3) + 3x^(2) - 2x - 4)/(x + 1)
= x^(2) + 2x - 4
So, x^(3) + 3x^(2) - 2x - 4 = (x + 1)(x^(2) + 2x - 4)
Now, to find other zeros of a function we solve the quadratic equation x^(2) + 2x - 4 = 0
⇒ x^(2) + 4x - 2x - 4 = 0
⇒ x(x + 2) - 2(x + 2) = 0
⇒ (x + 2)(x - 2) = 0
⇒ x + 2 = 0 or x - 2 = 0
⇒ x = -2 or x = 2
This means, x = -2 and x = 2 are other zeros of a function.

Use the linear combination method to solve this system of equations. What is the value of x?
Negative 2.4 x minus 3.6 y = 1.2. 2.4 x + 1.2 y = 1.2.
Answer:
x = 1
Step-by-step explanation:
We want to solve the equations for x
-2.4x-3.6y = 1.2
2.4x + 1.2y = 1.2
Add the two equations
-2.4y = 2.4
y = 2.4/-2.4
y = -1
To get x, simply substitute the y-value into any of the equations;
2.4x + 1.2y = 1.2
2.4x + 1.2(-1) = 1.2
2.4x -1.2 = 1.2
2.4x = 1.2 + 1.2
2.4x = 2.4
x = 2.4/2.4
x = 1
Answer:

If the demand (price) function is P(Q) = 100 − 4Q, find expressions for revenue function, R(Q) and marginal revenue function, MR(Q). Hence estimate the MR for 10 units of sales.
Answer:
R (Q) = 100Q - 4Q^2 , MR = 100 - 8Q , MR at Q (10) = 20
Step-by-step explanation:
Demand curve ie Price as a function of Quantity ; P (Q) = 100 - 4Q
R, total revenue from sale = Q . P (Q)
R (Q) = (100 - 4Q) Q
R (Q) = 100Q - 4Q^2MR is addition to total revenue due to per unit change in sale, = d R / d Q
d ( 100Q - 4Q^2 ) / d Q
MR = 100 - 8QMR at quantity , 10 unit of sales = 100 - 8 (10)
MR at Q (10) = 20
