The coordinates of the vertices after a dilation with a scale factor of 1/3 centered at the origin is E'(0, -2), F'(3, -2), G'(3, 1) and H'(0, 1).
What is Dilation?Dilation is a type of transformation where the figure is enlarged or made smaller such that it preserves the shape but not size.
Every dilated image are similar figures to the original figure.
Given that center of the dilation is origin.
Any coordinate (x, y) when dilated to a scale factor k is (kx, ky).
The coordinates of the quadrilateral are E(0, -6), F(9, -6), G(9, 3) and H(0, 3).
Dilation is with a scale factor of 1/3.
So all the coordinates become (1/3x, 1/3y).
E(0, -6) becomes E'(0, -2)
F(9, -6) becomes F'(3, -2)
G(9, 3) becomes G'(3, 1)
H(0, 3) becomes H'(0, 1)
Hence the coordinates are E'(0, -2), F'(3, -2), G'(3, 1) and H'(0, 1).

It take him to 7 minutes reach the ground. You can calculate the tangent height of an object using the distance and angles
What is the height formula?By multiplying "D * tan (theta)," where "tan" is the tangent of angle theta, you can determine the height of the object of interest. For instance, rounding up, the height is 40 tan 50 = 47.7 metres if theta is 50 degrees and D is 40 metres.
rate of descent=30 feet per minute
Height of climb=250 feet
Since he jumped 40 feet in no time,
hence,

What is Riemann sum formula?
A Riemann sum is a method used to approximate the definite integral of a function. A definite integral is a measure of the area between a function and the x-axis over a certain interval. The Riemann sum formula is used to approximate this area by breaking up the interval into a number of subintervals (or "rectangles") and summing the areas of each rectangle. The formula for a Riemann sum is given by:
∑ f(x_i) * Δx
where f(x) is the function being integrated, x_i is the right endpoint of the i-th subinterval, Δx is the width of the subinterval, and the sum is taken over all the subintervals.
The Riemann sum formula is defined with a limit, as the number of subintervals approaches infinity and the width of subintervals approaches zero, the Riemann sum formula becomes the definite integral.
There are different ways to calculate Riemann sum, such as Left Riemann Sum, Right Riemann Sum, Midpoint Riemann Sum, and Trapezoidal Riemann Sum, each one of them has different ways to calculate x_i, thus leading to different results, but all of them approach the definite integral as the number of subinterval increases.

The function f(x) = 2x2 + 2 represents the rate of a bus traveling in miles per hour. The function g(x) = x + 2 represents the time the bus traveled in hours. Solve (f ⋅ g)(3), and interpret the answer.
(f ⋅ g)(3) = 100, the distance in miles the bus traveled
(f ⋅ g)(3) = 100, the number of buses
(f ⋅ g)(3) = 25, the distance in miles the bus traveled
(f ⋅ g)(3) = 25, the number of buses
Answer:
(f ⋅ g)(3) = 100, the distance in miles the bus traveled
Step-by-step explanation:
The product of (miles/hour) and (hours) is (miles), so only answers with units of distance are applicable. The numbers are ...
f(3) = 2·3² +2 = 20 . . . . miles per hour
g(3) = 3+2 = 5 . . . . hours
so (f·g)(3) = f(3)·g(3) = 20·5 = 100 . . . . miles
Answer:
(f ⋅ g)(3) = 100, the distance in miles the bus traveled.
Step-by-step explanation:
Given functions:
[tex]\begin{cases}f(x)=2x^2+2\\g(x)=x+2\end{cases}[/tex]
To calculate the composite function (f ⋅ g)(3), multiply function f(3) by function g(3).
[tex]\begin{aligned}(f \cdot g)(3)&=f(3) \cdot g(3)\\&=(2(3)^2+2)(3+2)\\&=(2(9)+2)(3+2)\\&=(18+2)(3+2)\\&=(20)(5)\\&=100\end{aligned}[/tex]
If function f(x) represents the rate of a bus travelling in miles per hour,
and function g(x) represents the time the bus travelled in hours:
[tex]\implies f(x) \cdot g(x)=\rm miles/hour \cdot hour=\dfrac{miles}{hour} \cdot hours=miles=distance[/tex]
Therefore, (f ⋅ g)(3) = 100 represents the distance in miles the bus traveled.

Why is 8 not a perfect number?
8 is not a perfect number as sum of its proper divisors is not equal to 8.
A perfect number is a positive integer that is equal to the sum of its proper divisors, which are the divisors of the number excluding the number itself. In other words, a perfect number is a number that can be written as the sum of its divisors, excluding itself.
For example, the number 6 is a perfect number because its divisors are 1, 2, and 3, and 1+2+3 = 6.
8 is not a perfect number because it is not equal to the sum of its proper divisors. The divisors of 8 are 1, 2, 4, and 8, and 1+2+4 = 7, which is less than 8.
Therefore, 8 is not a perfect number. To this date, only 49 known perfect numbers have been found, they are all even numbers and the largest known perfect number is 2^(74,207,281) − 1, it has over 22 million digits.

What is a quadrilateral?
A quadrilateral is a closed shape that has four sides, four vertices, and four angles. It's made by connecting four non-collinear points. The sum of quadrilateral interior angles is always 360 degrees.
Assume that ABCD is a quadrilateral.
The sum of the interior angle and the corresponding exterior angle is 180°.
The exterior angle of A is E. The exterior angle of B is F. The exterior angle of C is G. The exterior angle of D is H.
Thus ∠A + ∠E = 180° .....(i)
∠B + ∠F = 180° ......(ii)
∠C + ∠G = 180° ......(iii)
∠D + ∠H = 180° ......(iv)
Add equations (i), (ii), (iii), (iv):
∠A + ∠E + ∠B + ∠F + ∠C + ∠G + ∠D + ∠H = 180°+180°+180°+180°
(∠A+∠B + ∠C +∠D) + ∠E +∠F + ∠G + ∠H = 720°
The sum of all interior angles of quadrilateral is ∠A+∠B + ∠C +∠D = 360°.

x=8-2y,3x+y=6 solving linear equations
Answer:
So the solution is x = -0.57 and y = 30/7.
Step By Step Explanation:
To solve a system of linear equations, such as "x = 8 - 2y" and "3x + y = 6", we can use substitution or elimination method.
Using substitution method:
solve one equation for one variable
substitute the expression obtained in step 1 into the second equation
solve the equation obtained in step 2 to find the value of the variable that was solved for
substitute this value back into the first equation to find the value of the other variable.
x = 8 - 2y;
3x + y = 6;
solve for x in the first equation
x = 8 - 2y
substitute the value of x in the second equation
3(8-2y) + y = 6
solve the second equation obtained for y
24 - 6y + y = 6
25 - 6y = 6
-6y = -19
y = 19/6
substitute the value of y back in the first equation
x = 8 - 2(19/6) = 8 - (38/6) = 8 - (63/6) = 8 - (63/6) = 8 - 10.5 = -2.5
So the solution is x = -2.5 and y = 19/6
Alternatively, using elimination method:
Add or subtract one equation from the other to eliminate one of the variables.
Solve the resulting equation for the remaining variable.
Substitute this value into either of the original equations to find the value of the eliminated variable.
Multiply the first equation by -3
-3x = -24 + 6y;
Add the above equation to the second equation
-3x + y = 6
-24 + 6y + y = 6
-24 + 7y = 6
7y = 30
y = 30/7
substitute the value of y into the first equation
x = 8 - 2(30/7) = 8 - (60/7) = 8 - (60/7) = 8 - 8.57 = -0.57
So the solution is x = -0.57 and y = 30/7.

What are polynomials?Algebraic expressions called polynomials include constants and indeterminates.
Polynomials can be thought of as a type of mathematics.
Nearly all branches of mathematics employ them to express numbers, and calculus is one of those branches where they play a crucial role.
A specific kind of expression is a polynomial.
A mathematical statement without the equals symbol (=) is called an expression. Let's examine the definition and usage of polynomials as they are described below.
An algebraic expression known as a polynomial requires that all of its exponents be whole numbers.
Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.
Hence, 1 - √5x is not a polynomial.

Currently, she has orders for more than 540 cupcakes.
Which inequality represents how many days it will take
Rebecca to complete her orders?
A x ≥ 3
B x≤ 3
C
x> 3
D x<3
option A The inequity x ≥ 3 indicates how many days it will take Rebecca to finish her orders.
what is inequality ?An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal symbol (). Different inequalities are used to contrast values, no matter how small or large. Many simple inequalities can be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.
given
180x3=540 is the value.
0x3=0 3x8 =24
Add 1+2 tens and the tens on top of the one to obtain 540.
