Find mPQ in the circle to the right
Given C is the midpoint of line AB, D is the midpoint of line AC, and E is the midpoint of line DC. If AE=16, what is DB?
Answer:
DB = 32
Step-by-step explanation:
Given :
⇒ C is the midpoint of the line AB
⇒ E is the midpoint of the line DC
⇒ AE = 16
=============================================================
Understanding :
⇒ AC = BC = 1/2AB
⇒ AD = DC = 1/2AC = 1/4AB
⇒ DE = 1/2AD = 1/4AC = 1/8AB
=============================================================
Finding AB :
⇒ AE = AD + DE
⇒ 16 = 1/4AB + 1/8AB
⇒ 3/8AB = 16
⇒ AB = 16 x 8 / 3
⇒ AB = 128/3
=============================================================
Finding DB :
⇒ DB = DC + CB
⇒ DB = 1/4AB + 1/2AB
⇒ DB = 3/4AB
⇒ DB = 3/4 × 128/3
⇒ DB = 128/4
⇒ DB = 32

Determine the equation of the elastic curve for the beam using the x1 coordinate for 0 ≤ x1 ≤ l/2
The elastic curve between 0 to L/2 is a cubic curve. And the elastic curve is shown in the given diagram.
What is an elastic curve?The flexible curve of a beam is the curve generated by the crossover of the horizontal member with the beam's side, with continuous stresses on the fibers considered to be within the elastic limit.
The slope at L/2 will be
[tex]\rm \theta _{L/2} = \dfrac{PL^2}{8EI}[/tex]
The deflection of the beam at L/2 will be
[tex]\rm y_{L/2} = \dfrac{P(L/2)^3}{3EI}\\\\\rm y_{L/2} = \dfrac{PL^3}{24EI}[/tex]
And the deflection of the beam at L will be
[tex]\rm y_{L} = \dfrac{PL^3}{24EI} + \dfrac{L}{2} \times \theta _{L/2} \\\\\rm y_{L} = \dfrac{PL^3}{24EI} + \dfrac{L}{2} \times \dfrac{PL^2}{8EI}\\\\\rm y_{L} = \dfrac{5PL^3}{48EI}[/tex]
Then the elastic curve will be shown in the diagram.

Solve for the value of x :-
5(x+4)+5(2-x)
Answer:
[tex]30[/tex]
Step-by-step explanation:
Given expression:
[tex]5(x + 4) + 5(2 - x)[/tex]
Note: The value of "x" is undefined because the given sum is not an equation. Thus, I will simplify the expression as much as possible.
Let us simplify all the distributive properties stated in the expression.
Apply the distributive property rule [a(b + c) = ab + ac]
[tex]\implies5(x) + 5(4) + 5(2) - 5(x)[/tex]
Since 5(x) is being subtracted from 5(x), we get:
[tex]\implies 5(x) + 5(4) + 5(2) - 5(x)[/tex]
[tex]\implies 5(4) + 5(2)[/tex]
Finally, let us simplify the sum of the product of (5 and 4) and (5 and 2).
[tex]\implies20 + 10[/tex]
[tex]\implies \boxed{30}[/tex]

What are geometric sequences?
What does x equal with this equation
x/6-33= -27
Answer:
The first thing that we have to do is add 33 to both sides to try to reduce the amount of variables on the left hand side.
[tex]\frac{x}{6} - 33 = -27[/tex]
[tex]\frac{x}{6} - 33 + 33 = -27 + 33[/tex]
[tex]\frac{x}{6} = 6[/tex]
Now that we have simplified the left hand side even more we only have one part left to get x by itself which is to multiply both sides by 6.
[tex]\frac{x}{6} = 6[/tex]
[tex]\frac{x}{6} * 6 = 6 * 6[/tex]
[tex]x = 36[/tex]
Therefore, our final answer for what the value of x equals is 36.

Find the equation of a line passing through the same point that f(x) passes through at x = 3 with a slope equal to the limit
you found in part A.
the equation in part A is x^3-4x^2+2 and when x=3 y=-7 so, (3,-7) is the point the equation for part B needs to pass through
The linear equation that has a slope of -7 and crosses the x-axis at (3, 0) is:
y = -7x + 21
How to find the linear equation?
A general linear equation is:
y = a*x +b
Where a is the slope and b is the y-intercept.
The slope must be equal to the limit found in part a, and you say that it is equal to -7, so the slope is -7. And for how is written the problem, I understand that it crosses the x-axis at x = 3.
Then we will have:
y = -7*x + b
Such that, when x = 3, y = 0, then:
0 = -7*3 + b
21 = b
Then the linear equation is y = -7x + 21

Brief History:
While a circle, symbolically, represents many different things to many different groups of people including concepts such as eternity, timelessness, and totality, a circle by definition is a simple closed shape. It is a set of all points in a plane that are equidistant from a given point, called the center. It can also be defined as a curve traced by a point where the distance from a given point remains constant as the point moves. The distance between any point of a circle and the center of a circle is called its radius, while the diameter of a circle is defined as the largest distance between any two points on a circle. Essentially, the diameter is twice the radius, as the largest distance between two points on a circle has to be a line segment through the center of a circle. The circumference of a circle can be defined as the distance around the circle, or the length of a circuit along the circle. All of these values are related through the mathematical constant π, or pi, which is the ratio of a circle's circumference to its diameter, and is approximately 3.14159. π is an irrational number meaning that it cannot be expressed exactly as a fraction (though it is often approximated as 22/7) and its decimal representation never ends or has a permanent repeating pattern. It is also a transcendental number, meaning that it is not the root of any non-zero, polynomial that has rational coefficients. Interestingly, the proof by Ferdinand von Lindemann in 1880 that π is transcendental finally put an end to the millennia-old quest that began with ancient geometers of "squaring the circle." This involved attempting to construct a square with the same area as a given circle within a finite number of steps, only using a compass and straightedge. While it is now known that this is impossible, and imagining the ardent efforts of flustered ancient geometers attempting the impossible by candlelight might evoke a ludicrous image, it is important to remember that it is thanks to people like these that so many mathematical concepts are well defined today.
