find the perimeter of the polygon with vertices U (-2,4) V (3,4) and W (3,-4)
So the perimeter of the polygon with vertices U (-2,4) V (3,4) and W (3,-4) is Perimeter = 22.434
Perimeter of any close shape is the total length of the boundary of any closed shape.
We have been given vertices of polygon that are U (-2,4) V (3,4) and W (3,-4)
To find the perimeter we need to find the length of all three sides, and we do that by finding the distance between the points that form the sides:
The formula for the distance between two points is:
[tex]$d=\sqrt{\left(x_1-x_2\right)^2+\left(y_1-y_2\right)^2}$[/tex]
side UV:
[tex]$U V=\sqrt{(-2-3)^2+(4-4)^2}=5$[/tex]
side VW:
[tex]$V W=\sqrt{(3-3)^2+(4-(-4))^2}=8$[/tex]
side UW:
[tex]$U W=\sqrt{(-2-3)^2+(4-(-4))^2}=9.434$[/tex]
So the perimeter is:
P=UV+VW+UW
[tex]$P=5+8+9.434=22.434$[/tex]
So the perimeter is: 22.434

The experimental method has one advantage over the correlational method in that it "determines cause and effect," whereas the correlational study does not.
What is defined as correlational method?Quantitative methods are used in both experimental and correlational research to investigate interactions between variables. However, there are significant differences with how data is gathered as well as the conclusions that can be drawn.
A correlational research design looks into interactions between variables without allowing the researcher to control or manipulate any of them.A correlation is a measurement of the strength and/or direction of a relation between two (or more) variables. A correlation's direction may be positive or negative.What is defined as experimental method?Experimental research is scientific research that employs two sets of variables. The first set serves as a constant against which the differences in the second set are measured. Experimentation is used in quantitative research, for example.
If you lack sufficient information to back up your decisions, you should first establish the facts. Experimental research collects the information needed to make better decisions.Experimentation is used in any research done under scientifically acceptable conditions.To know more about the correlational method, here

Complete the point-slope equation of the line through (-4,8) (−4,8)
Use exact numbers.
(Point-Slope Equation)
any detailed answer for this??
Answer: y = 8
Step-by-step explanation:
Point-slope form is written as y - [tex]y_1[/tex] = m(x - [tex]x_1[/tex]) where m is the slope and ([tex]x_1[/tex] , [tex]y_1[/tex]) are points on the line.
First, we need to find the slope. This can be found with change in y over change in x:
[tex]\displaystyle \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
[tex]\displaystyle \frac{8-8}{-4--4}=\frac{0}{-4+4}=\frac{0}{0}=[/tex] undefined
Now, we will plug this undefined slope (0) into the equation below. Anything times 0 is 0, so no matter what (x - [tex]x_1[/tex]) is, the right side of the equation will always be 0.
y - [tex]y_1[/tex] = m(x - [tex]x_1[/tex])
y - [tex]y_1[/tex] = (0)(x - [tex]x_1[/tex]) ➜ y - [tex]y_1[/tex] = 0
Lastly, we will take the y-value of 8 and plug it into the equation and simplify.
y - [tex]y_1[/tex] = 0 ➜ y - (8) = 0 ➜ + 8 (y - 8) = (0) + 8
y = 8

New, larger bottle of shampoo contains 20 ounces. the bottle says you get 33% more than the amount in the original bottle. how many ounces of shampoo were in the original bottle?
Amount of shampoo in the original bottle is 15.0376 ounces.
Larger bottle of shampoo contains = 20 ounces
Let, amount of shampoo in the original bottle = x ounces
33% of amount of shampoo in the original bottle = ((33x)/100)
According to the question, amount of shampoo in the larger bottle is 33% more of amount of shampoo in the original bottle. So, mathematically we can write
20 = x + ((33x)/100)
⇒ 20 = x + 0.33x
⇒ 20 = 1.33 x
⇒ x = 20/1.33
⇒ x = 15.0376
Amount of shampoo in the original bottle is 15.0376 ounces.

We get the values of m as 1 and n as 0.
We are given a function:
f(x) = m / (x - 1) + n
We are also given that:
f (-2) = 1 and f (4) = 3
We have to find the value of m and n.
f (-2) = m (2 - 1) + n
1 = m + n
n = 1 - m
f (4) = m / (4 - 1) + n
3 = 3 m + n
3 = 3 m + 1 - m
3 = 2 m + 1
2 m = 3 - 1
2 m = 2
m = 2 / 2

Here are two expressions whose sum is a new expression, A.
(2x2+5)+(6x□−7)=A
Select all the values that we can put in the box so that A is a polynomial.
Answer:
D, F and G
Step-by-step explanation:
A polynomial must have a negative exponent for the variable term. So we can eliminate A, B and C
Also no fractional exponents so eliminate E
F & G are positive exponents so acceptable
D has the exponent 0 so the term becomes (2x² + 5) + (6x⁰ + 7)
x⁰ = 1 so the expression becomes 2x² + 5 + 6 + 7 = 2x² + 18 which is a polynomial.
he zeros of a quadratic function are 6 and -4. Which of these choices could be the function?
A.

f(x) = (x + 6)(x − 4)
C.
f(x) = (x − 6)(x + 4)
D.
f(x) = (x − 6)(x − 4)
Answer:
C
Step-by-step explanation:
given the zeros x = a and x = b then the corresponding factors are
(x - a) and (x - b)
then f(x) is the product of these factors
given zeros x = 6 and x = - 4 then the factors are
(x - 6) and (x - (- 4)) , that is (x - 6 and (x + 4) , then
f(x) = (x - 6)(x + 4)
1. (2x - 3)² = 18
2. 2 (5x + 2)² = 64
solve using Quadratic Equation
1) The solution to the given quadratic equation is; x = ¹/₂(3 ± 3√2)
2) The solution to the given quadratic equation is; x = 5/6 or -2
How to find the roots of quadratic equations?
1) (2x - 3)² = 18
To fid the value of x, we can solve by first taking the square root of both sides to get;
√(2x - 3)² = ±√18
Add 3 to both sides using addition property of equality to get;
2x - 3 = ±3√2
2x = 3 ± 3√2
x = ¹/₂(3 ± 3√2)
2) 2(5x + 2)² = 64
To fid the value of x, we can solve by first dividing both sides to get;
(5x + 2)² = 32
Take square root of both sides to get;
(5x + 2) = ±8
Subtract 2 from both sides using subtraction property of equality to get;
5x + 2 = ±8
5x = ±8 - 2
5x = 6 or 5x = -10
x = 5/6 or -2

Teresa made a circular plywood cover bigger than the mouth of the mixing bowl. it is 20 cm in diameter. but in using the mixer, the cover must have a hole in the middle to insert the mixing tool. if the hole is 10 cm in diameter, what is the final area of the mixer cover?
The final area of the mixer cover is 1650/7 square cm.
Given that:-
Diameter of circular plywood cover = 20cm
Diameter of circular hole in the middle = 10cm
We have to find the final area of the mixer cover after cutting the hole in the middle.
We can find the radius of the circular cover and the circular hole using their respective diameters.
Hence,
Radius of circular plywood cover = 20/2 = 10 cm
Radius of circular plywood cover = 10/2 = 5 cm
We know that,
Area of circle = [tex]\pi r^2[/tex]
Hence,
Area of circular plywood cover = [tex]\frac{22}{7}*(10)^2 =\frac{2200}{7}[/tex]
Area of circular hole = [tex]\frac{22}{7}*(5)^2 =\frac{550}{7}[/tex]
Final area = Area of circular plywood cover - Area of circular hole

What is a linear function?A linear function is modeled by the following rule:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, the change in y divided by the change in x.b is the y-intercept, which is the the value of y when the function crosses the x-axis, that is, when x = 0.Another feature of linear functions is uniform behavior, as they are either increasing or decreasing over the entire domain, there are no changes from increasing to decreasing.
Heights increase or decrease over the domain, hence they are not linear, while the area of the square is quadratic, as A = s².
One hour has 3600 seconds, hence the number of seconds in a number of hours is modeled by the following linear function:
