What are coordinates of the circumcenter?
Answers
The coordinate of the given figure is (5,5) (5,-3) and (-1, -3). The coordinates of the circumcenter of the triangle is (2,1).
What is a triangle?A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
We can see the given triangle.
The coordinates of A are (-1,-3).
The coordinates of B are (-1,-3).
The coordinates of C are(5,5).
We know that the circumcenter of a right triangle is the midpoint of the hypotenuse.
Mid-point of hypotenuse AC is given by
[tex]x = x_1 +x_2 / 2\\y = y_1 +y_2 / 2[/tex]
So, x =( -1 + 5)/2 = 2
y =( 5-3)/2 = 1
Hence, the circumcenter of the triangle is (2,1).

Answer:
It is health.
Step-by-step explanation:
It says that "The larger the MAD, the greater variability there is in the data (the data is more spread out)." So History would actually be the most wrong one. Health is the lowest value so Health is correct.
Answer:
Health
Step-by-step explanation:
MAD = median absolute deviation
It measures how spread out a set of data is, and is less affected by extremely high or low values.
The bigger the variance, the more spread out the data points are.
The smaller the variance, the less spread out the data points are.
Therefore, the scores were closest together in Health, since this has the smallest MAD.

A set of equations is given below: equation e: m = 4n 1 equation f: m = 6n 8 which statement describes a step that can be used to find the solution to the set of equations? equation f can be written as m = 6(m − 1) 8. equation f can be written as m = 4(m − 8) 1. equation f can be written as 4n 1 = 6n 8. equation f can be written as n 1 = 6n 8.
Answers
The statement that describes a step to find the solution to the set of equations is the equation f can be written as 4n + 1 = 6n + 8
How to solve the equation?The system of equations is given as:
m = 4n + 1
m = 6n + 8
To solve the equation, we simply substitute 4n + 1 for m in the second equation.
So, we have:
4n + 1 = 6n + 8
Hence, the equation f can be written as 4n + 1 = 6n + 8

if x-y=80 and 3/5=y/x <--(as a fraction), what is the value of x? will give 45 points, and brainliest for the right answer
Answers
Answer:
(200, 120)Step-by-step explanation:
Given system
x - y = 803/5 = y/xSolve it by substitution
y = 3/5(x)y = x - 80Find the value of x
3/5(x) = x - 80x - 3/5(x) = 802/5(x) = 80x = 80*5/2x = 200Find the value of y
y = 3/5(200)y = 120Answer:
x = 200
Step-by-step explanation:
Given system of equations:
[tex]\begin{cases}x-y=80\\\\\dfrac{3}{5}=\dfrac{y}{x} \end{cases}[/tex]
Rearrange the second equation to make y the subject by multiplying both sides by x:
[tex]\implies \dfrac{3}{5} \cdot x=\dfrac{y}{x} \cdot x[/tex]
[tex]\implies y=\dfrac{3}{5}x[/tex]
Substitute this into the first equation and solve for x:
[tex]\implies x-\left(\dfrac{3}{5}x\right)=80[/tex]
[tex]\implies \dfrac{2}{5}x=80[/tex]
[tex]\implies \dfrac{2}{5}x \cdot 5=80 \cdot 5[/tex]
[tex]\implies 2x=400[/tex]
[tex]\implies \dfrac{2x}{2}=\dfrac{400}{2}[/tex]
[tex]\implies x=200[/tex]
Therefore, the value of x is 200.
If you want to find the value of y, simply substitute the found value of x into the first equation and solve for y:
[tex]\implies 200-y=80[/tex]
[tex]\implies 200-y+y=80+y[/tex]
[tex]\implies 200=y+80[/tex]
[tex]\implies 200-80=y+80-80[/tex]
[tex]\implies 120=y[/tex]
[tex]\implies y=120[/tex]

Write 2/7x(1.4x^2-3.5y) as a polynomial
Answers
Answer:
0.4x^3 - xy.
Step-by-step explanation:
2/7x(1.4x^2-3.5y) Distributing the2/7x over the parentheses:
= 2/7 * 1.4 x^3 - 2/7 *3.5xy
= 0.4x^3 - xy
The expression 2/7x(1.4x² - 3.5y) can be written as the polynomial (4/5)x³ - (10/7)xy.
What is a polynomial?A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.
To write 2/7x(1.4x² - 3.5y) as a polynomial, we need to first simplify the expression inside the parentheses by distributing the 2/7x:
2/7x(1.4x² - 3.5y) = (2/7x)(1.4x²) - (2/7x)(3.5y)
Next, we can simplify each term by multiplying the coefficients:
2/7x(1.4x² - 3.5y) = (4/5)x³ - (10/7)xy
Thus, 2/7x(1.4x² - 3.5y) can be written as the polynomial (4/5)x³ - (10/7)xy.

A portable fuel tank used to transport gasoline is in the shape of a rectangular prism.
The tank is 5 feet longer than it is wide and 29 feet deeper than it is wide.
The volume of the tank is 33,488 cubic feet.
Let the width of the rectangular prism be w. Then we have
length = w + 5
height = w + 29
Then the volume is given as
Volume = l × w × h
33488 = (w + 5) (w) (w + 29)
Then we have
[tex]\begin{aligned} \rm w^3 + 5w^2 + 29w^2 + 145w &=33488 \\\\\rm w^3 + 34w^2 + 145w - 33488 &= 0\\\\\rm (w - 23)(2w+57)(2w + 57) &= 0\\\\\rm w &= 23, -28.5, -28.5 \end{aligned}[/tex]

Step-by-step explanation:
Which two values multiply to (-24) and add to (5)?
These values are (-3) and (8):
-3 x 8 = -24
-3 + 8 = 5
As such, the factors include these two values. One of the factors (x + 8), is one of the answer choices.
x² + 5x - 24 = (x - 3)(x + 8)
