To determine the longest segment, we calculate the distances between the given points using the distance formula. The longest segment is DE with a distance of approximately 21.43 meters.
Explanation:To determine which segment is the longest, we need to find the distance between each pair of points. Using the distance formula, we can calculate the distance between points D and E, points E and F, points F and G, and points G and H. By comparing these distances, we can determine which segment is the longest.
D = sqrt((-3 - 8)^2 + (-6 - 11)^2) = sqrt(169 + 289) = sqrt(458) ≈ 21.43
E = sqrt((8 - 13)^2 + (11 - 13)^2) = sqrt(25 + 4) = sqrt(29) ≈ 5.39
F = sqrt((13 - 8)^2 + (13 - 11)^2) = sqrt(25 + 4) = sqrt(29) ≈ 5.39
G = sqrt((8 - -3)^2 + (11 - 13)^2) = sqrt(121 + 4) = sqrt(125) ≈ 11.18
H = sqrt((13 - -3)^2 + (13 - 11)^2) = sqrt(256 + 4) = sqrt(260) ≈ 16.12
The longest segment is DE with a distance of approximately 21.43 meters.

The equation for the circle is:
x²+y²+14x+10y−7=0 .
What is the center of the circle?
Answer:
(-7,-5)
Step-by-step explanation:
Converting the circle into the form (x-h)^2+(y-k)^2=r^2, we get
x^2+14x+49+y^2+10y+25=7+25+49
So we get
(X+7)^2+(y+5)^2=81
So the center of the circle is (-7,-5)
Answer:
centre = (- 7, - 5)
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Arrange the equation by placing the x and y terms together
x² + 14x + y² + 10y - 7 = 0 ( add 7 to both sides )
x² + 14x + y² + 10y = 7
Use the method of completing the square
add (half the coefficient of the x/y term)² to both sides
x² + 2(7)x + 7² + y² + 2(5)y + 5² = 7 + 7² + 5²
(x + 7)² + (y + 5)² = 7 + 49 + 25 = 81 ← in standard form
with (h, k) = (- 7, - 5) ← centre of circle

Step 1: Plug 6x - 11 in for y in the equation -2x - 3y = -7
-2x - 3(6x-11) = -7
Step 2: Distribute -3 to the numbers inside the parentheses (6x -11)
-2x - 18x + 33 = -7
Step 3: Combine like terms
x's go with x's
-20x + 33 = -7
Step 4: Subtract 33 to both sides
-20x = -40
Step 5: Isolate x by dividing -20 to both sides
x = 2
Step 6: To solve for y plug 2 in for x in the equation y = 6x - 11
y = 6(2) - 11
y = 12 - 11
y = 1

The number of tickets sold is an example of continuous data. True or False?
Answer:
False
Step-by-step explanation:
Continuous data is data that can take any value within a range, including non-whole number values.
Because the number of tickets sold can only take whole number values, it is not an example of continuous data.
False
I hope this helps you understand continuous data. Have a great day. :)
Answer: False
Step-by-step explanation: Continuous data is data that can be measured. The number of tickets that were sold would only be positive integers meaning that there can't be a fraction of a ticket sold. Since discrete data is data that can be counted, the number of tickets sold would be an example of data that is discrete.

Which are the solutions of x2 = –11x + 4?
Answer:
x = 0.35 or x = -11.35
Step-by-step explanation:
Points to remember
Solution of a quadratic equation ax² + bx + c = 0
x = [-b ± √(b² - 4ac)]/2a
It is given that, x² = –11x + 4
x² + 11x - 4 = 0
To find the solution
Here a = 1, b = 11 and c = -4
x = [-b ± √(b² - 4ac)]/2a
x = [-11 ± √(11² - 4 * 1 * (-4))]/2*1
= [-11 ± √(121 + 16)]2
= [-11 ± √137]/2
= [-11 ± 11.70]/2
x = -11 + 11.70 or x = -11 - 11.70
x = 0.35 or x = -11.35
10 points One question NEED TO SHOW WORK
Answer:
h = 3πx
Step-by-step explanation:
The volume (V) of the cylinder is calculated using the formula
V = πr²h ( r is the radius and h the height )
V = π × x² × 3x = 3πx³
The volume of the cuboid therefore has volume of 3πx³, that is
x × x × h = 3πx³
x²h = 3πx³ ( divide both sides by x² )
h = 3πx³ ÷ x² = 3πx

solve by completing the square x^2+12x+32=0
Answer:
hello : x = - 4 or x = - 8
Step-by-step explanation:
x²+12x+32=0
(x² +2(6)(x) +6²) - 6² +32 = 0....by completing the square
(x + 6 )²- 2² = 0
(x+6-2)(x+6+2)=0 by idetity : a² - b² = (a - b ) ( a + b )
(x+4)(x+8) =0
x+4=0 or x+8= 0
x = - 4 or x = - 8
Answer:
x = - 8, x = - 4
Step-by-step explanation:
Given
x² + 12x + 32 = 0 ( subtract 32 from both sides )
x² + 12x = - 32
To complete the square
add (half the coefficient of the x- term)² to both sides
x² + 2(6)x + 6² = - 32 + 6²
(x + 6)² = - 32 + 36 = 4
Take the square root of both sides
x + 6 = ± 2 ( subtract 6 from both sides )
x = - 6 ± 2
Hence
x = - 6 - 2 = - 8
x = - 6 + 2 = - 4
If y varies inversely with x and y =5 when x=2.5 what is the value of y when x=20
Answer:
If x = 20, then y = 12.5/20 = 0.625
Step-by-step explanation:
The pertinent relationship is y = k/x, where k is the constant of proportionality.
Subbing 5 for y and 2.5 for x yields 5 = k/2.5, so k = 12.5.
Then the specific relationship fit to this problem is y = 12.5/x.
If x = 20, then y = 12.5/20 = 0.625

Jolene invests her savings in two bank accounts, one paying 6 percent and the other paying 9 percent simple interest per year. She puts twice as much in the lower-yielding account because it is less risky. Her annual interest is 7266 dollars. How much did she invest at each rate?
Amount invested at 6 percent interest is $
Amount invested at 9 percent interest is $
Answer:
Amount invested at 6 percent interest is $69,200
Amount invested at 9 percent interest is $34,600
Step-by-step explanation:
Let the amount invested (or principal) at 6 percent interest be $2x
The principal(P) (amount invested) at 9 percent interest will be $x
Amount(A) = P(1 + rt)
Time(t) = one year = 1
Amount at 6% interest = 2x(1 + 0.06) = $2.12x
Interest accumulated = Amount - Principal = $2.12x - $2x = $0.12x
Amount at 9% interest = x(1 + 0.09) = $1.09x
Interest accumulated = Amount - Principal = $1.09x - $x = $0.09x
Total interest = $7,266
So, $0.12x + $0.09x = $7,266
$0.21x = $7,266
x = [tex]\frac{7,266}{0.21}[/tex] = $34,600
The principal (amount invested) at 9 percent interest rate is $34,600
The principal (amount invested) at 6 percent interest rate is 2 × $34,600 = $69,200

The length of a rectangle is 9 cm and width of the rectangle is 5 cm.
What is Area of Rectangle?The area of Rectangle is length times of width.
Length of a rectangle is 11 centimeters less than four times its width.
Length=4W-11
Width=W
Area=45
Area=Length×Width
=(4w-11)w
45=4w²-11w
4w²-11w-45=0
After applying a =4, b=-11 and c=-45 in the quadratic formula
we get w=5
Plug in the value of w in length
Length=4W-11
=4(5)-11
=20-11
=9
Hence, the length of a rectangle is 9 cm and width of the rectangle is 5 cm.

Answer:
the height is 20 inches
Step-by-step explanation:
Answer: 20 inches
Step-by-step explanation:
This is a triangular prism, we first need to find the area of the triangle!
A (triangle) = 1/2 x base of triangle x height of triangle
A = 1/2 x 3 x 5 = 7.5 square inches
Now lets work out the height of the prism, we can use the volume of the prism to do so.
V = Area of triangle x height
150 = 7.5 x height
Height = 150/7.5 = 20 inches
if y varies directly as z and inversely as x and y=16 and z=2 when x=42, find y when x=14 and z=8
*Edit* It's high school math. Forgot to change it from middle.
Answer:
y = 192
Step-by-step explanation:
Given y varies directly as z and inversely as x then the equation relating them is
y = [tex]\frac{kx}{z}[/tex] ← k is the constant of variation
To find k use the condition y = 16 and z = 2 when x = 42
k = [tex]\frac{yx}{z}[/tex] = [tex]\frac{16(42)}{2}[/tex] = 336
y = [tex]\frac{336z}{x}[/tex] ← equation of variation
When x = 14 and z = 8, then

What is the expression (3x²y³) ³
Final answer:
The expression (3x²y³) ³ is found by cubing the coefficient and multiplying each variable's exponent by 3, which results in 27x⁶y⁹.
Explanation:
When we deal with the cubing of exponentials, as in the expression (3x²y³) ³, both the numerical coefficient and the variables with their exponents are raised to the power of 3. The rules of exponents guide us to cube the number 3 and multiply the exponents of x and y by 3.
To cube the number 3, we would calculate 3³, which equals 27. For the variables, we apply the exponent to each exponent: x raised to the 2³ (which is 6) and y raised to the 3³ (which is 9). Hence, the expression (3x²y³) ³ simplifies to 27x⁶y⁹. This demonstrates that when cubing an exponential expression, we obtain a new exponent for each variable by multiplying the original exponent by 3, and we cube the numerical coefficient as well.
