How to translate a shape by using rigid transformations
In this problem we find a figure formed by eight vertices: (1, 3), (1, 4), (4, 4), (4, 3), (2, 3), (3, 3), (2, 1), (3, 1), each of which has to be modified by applying the translation vector (4, 5). Now we proceed to find the resulting coordinates:
(1, 3) + (4, 5) = (5, 8)
(1, 4) + (4, 5) = (5, 9)
(4, 4) + (4, 5) = (8, 9)
(4, 3) + (4, 5) = (8, 8)
(2, 3) + (4, 5) = (6, 8)
(3, 3) + (4, 5) = (7, 8)
(2, 1) + (4, 5) = (6, 6)
(3, 1) + (4, 5) = (7, 6)

coordinate geometry is a system that makes use of one or greater numbers, or coordinates, to uniquely determine the placement of the factors or other geometric factors on a manifold inclusive of Euclidean space.
The order of the coordinates is full-size, and they may be once in a while diagnosed through their function in an ordered tuple and sometimes via a letter, as in "the x-coordinate".
The coordinates are taken to be actual numbers in basic arithmetic, however may be complicated numbers or elements of a extra abstract system together with a commutative ring. the usage of a coordinate device permits troubles in geometry to be translated into issues approximately numbers and vice versa; that is the idea of analytic geometry

The Reunion Tower in Dallas, Texas, is topped by a spherical dome that has a surface area of approximately 13,924 \pi square feet. What is the volume of the dome? Round to the nearest tenth.
The volume of the spherical dome will be 12.9π cubic feet when the surface area of the dome is 13.924π.
What is the volume of the sphere?The volume of the cone is the amount of quantity, which is obtained in the 3-dimensional space. The dome is the shape of a semi-sphere the volume of the dome will be half of the volume of the sphere.
Given that the Reunion Tower in Dallas, Texas, is topped by a spherical dome that has a surface area of approximately 13,924π square feet.
The volume of the dome will be calculated as below:-
SA = 13.924π
2πr² = 13.92π
r = √6.96
r = 2.63 feet
Volume = 2 / 3 πr³
Volume = ( 2 / 3 ) π ( 2.63)³
Volume = 12.24π cubic feet

A speed skater moving across frictionless ice at 12 m/s hits a 7.0 m wide patch of rough ice. she slows steadily, then continues on at 6.0 m/s. what is her acceleration on the rough ice?
As per kinematic theory, when any object is moving on a rough surface, the friction force will act on the surface. And the friction force is in the opposite direction to the motion of the object.
Using kinematic formulas, the acceleration speed can be calculated:
[tex]v^{2} = u^{2} +2as[/tex]
As per the given data,
The initial speed of the skater [tex](u) = 12m/s[/tex]
The width of the pitch on the rough ice [tex](s) = 7.0 mt[/tex]
The final speed of the skater [tex](v) = 6.0m/s[/tex]
Substituting these values in the kinematic formula, we get
[tex]a = \frac{v^{2}-u^{2} }{2s}[/tex]
[tex]a = \frac{6^{2}-12^{2} }{14}[/tex]
[tex]a=- 7.71 m/s[/tex]
Therefore the calculated acceleration on the rough ice is [tex]-7.71m/s[/tex]

Slope = -1, through point (-3,5)
The equation of the line having slope = -1 and passing through a point (-3, 5) is y = -x + 2 and graph is given below.
The general equation of a line is y = m × x + c, where m is the slope and c is the y-intercept of the line.
Given slope is equal to -1.
Therefore the equation of the required line is y = (-1) × x + c.
Given that this line passes through the point (-3, 5).
Therefore we have 5 = (-1) × (-3) + c
⇒ 5 = 3 + c
⇒ 5 - 3 = c
⇒ 2 = c
⇒ c = 2
Therefore the y-intercept of the required line in cartesian coordinate form is (0, 2).
Therefore the required equation of the line is y = (-1) × x + 2

The solution of the system of the equations is gotten using substitution method and the values of the unknown are x = -8 and y = - 4
How to solve the system of equationsGiven data
x + 5y = -28
-x + y = 4
From -x + y = 4
step 1 make y the subject of formula to have

Using the critical value, we should reject the null.
What is a test statistic?A test statistic is a quantity derived from a sample that is used in statistical hypothesis testing. A hypothesis test is usually specified in terms of a test statistic, which is a numerical summary of a data set that reduces the data to a single value that can be used to perform the hypothesis test. In general, a test statistic is chosen or defined in such a way that it quantifies, within observed data, behaviors that distinguish the null hypothesis from the alternative hypothesis, where such an alternative is prescribed, or that characterize the null hypothesis if no alternative hypothesis is explicitly stated.So,
Test = 2.85Critical value = Z(0.05) = 1.645RR: Reject if the Z test > 1.645Z test = 2.85 > 1.645 ⇒ RejectTherefore, using the critical value, we should reject the null.

A variable is a sign and placeholder for any mathematical object (from the Latin variabilis, "changeable") in mathematics. A variable can, for example, represent a number, a vector, a matrix, a function, the argument of a function, a set, or a set's component.
Numerous issues are resolved in a single computation by using variables in algebraic calculations as if they were explicit integers. For instance, by exchanging the variables that represent them in the quadratic formula with the numerical values of the coefficients in any given quadratic equation, the quadratic formula may solve any quadratic equation. A variable in mathematical logic is either a symbol for an undefined term in the theory or an undefined phrase itself (a meta-variable).

Write an absolute value equation representing all numbers x whose distance from 4 is 3 units.
The equation is
(Type an equation using x as the variable.)
The equation is | x - 4 | = 3
Here, we are given that x represents all numbers that are at a distance of 3 units from 4.
Now, the distance of x from 4 can be in the positive direction or in the negative direction.
This can be represented by an absolute value function as follows-
| x - 4 | = 3
we can check our result by solving the given equation
| x - 4 | = 3 can be written as-
x - 4 = 3 or -x + 4 = 3

Two lines are interesting to each other at one point and make 4 angles which are as follows: Angle 1,2,3,4
If two lines intersect at a point, then the vertically opposite angles are always equal.
When two lines intersect at any point, the vertically opposite angles are equal and are known as the vertically opposite angles.
This is because any two pairs of adjacent angles will be supplementary pairs.

Solve for c
21 = 5/6c - 9
Answer:
C=36
Step-by-step explanation:
Answer:
c = 36
Step-by-step explanation:
so our equation is 21 = 5/6c - 9
first we need to get rid of the 9. in order to do this, we have to do the opposite of the action shown. so in this case, we would add 9 to both sides. we add it to both sides to keep the equation balanced and equal.
adding 9 to 21 gives us 30. so our equation would then be 30 = 5/6c
now we need to get the c by itself. so we divide by 5/6 because in the original equation the 5/6 and the c are being multiplied to each other.
when we devide 5/6c by 5/6, it cancels out. leaving us with c. 30 divided by 5/6 will in turn gives 36. and there is your answer.

since the edge length is four, you multiply that by 3 (length width and height are all 4) and that would be 12
since there are two you do two times 12= 24 (im not 100% sure cuz I haven't learned this yet)
