What is the perimeter of kite FGHJ? Round to 2 decimal places.
The perimeter of kite FGHJ is 39. Rounded to 2 decimal places, the answer is 39.00.
What is the perimeter?
The perimeter is the total distance around the boundary of a two-dimensional shape. It is calculated by adding up the lengths of all the sides of the shape.
First, we need to find the length of the other two sides of the kite:
Since FH = 17 and FT = 10, we can find the length of TH by subtracting: TH = FH - FT = 17 - 10 = 7.
Similarly, since GJ = 10 and TJ = 5, we can find the length of GT by subtracting: GT = GJ - TJ = 10 - 5 = 5.
Now we can find the perimeter of the kite by adding up the lengths of all four sides:
Perimeter = FH + TH + GJ + GT
Perimeter = 17 + 7 + 10 + 5
Perimeter = 39
Therefore, the perimeter of kite FGHJ is 39. Rounded to 2 decimal places, the answer is 39.00.

Question 4: You are creating an obstacle for a community event. The area of the rectangular space is represented by the expression 8x² - 12x. The width of the rectangular space is represented by the expression 4x.
Part A: Write an expression to represent the length of the rectangular space. Show all work to find the length
Length of Rectangular Space
Part B: Prove your answer from Part A is correct by multiplying the length and width of the rectangle.
Write the expression in standard form:
Answer:
Part A: To find the expression for the length of the rectangular space, we can use the formula for the area of a rectangle, which is length multiplied by width. We have the expression for the area as 8x² - 12x, and the expression for the width as 4x. So, we can write:
Area = Length × Width
8x² - 12x = Length × 4x
Simplifying the right side by multiplying, we get:
8x² - 12x = 4x × Length
2x² - 3x = Length
Therefore, the expression for the length of the rectangular space is 2x² - 3x.
Part B: To prove that the expression for the length from Part A is correct, we can multiply it by the expression for the width and simplify:
Length × Width = (2x² - 3x) × (4x)
= 8x³ - 12x²
= 4x(2x² - 3x)
= 4x(2x(x - 3))
This is in fact the same as the expression for the area of the rectangular space, 8x² - 12x, in standard form.

According to a random sample taken at 12 A.M., body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.33°F and a standard deviation of 0.67°F. Using Chebyshev's theorem, what do we know about the percentage of healthy adults with body temperatures that are within 2 standard deviations of the mean? What are the minimum and maximum possible body temperatures that are within 2 standard deviations of the mean?
Question content area bottom
Part 1
At least enter your response here% of healthy adults have body temperatures within 2 standard deviations of 98.33°F
At least 75% of healthy adults have body temperatures within the range of 96.99°F to 99.67°F.
What is standard deviations?
The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Chebyshev's theorem states that for any distribution (not just the normal distribution), regardless of shape, at least 1 - 1/k^2 of the data values will be within k standard deviations of the mean, where k is any number greater than 1.
In this case, we want to know the percentage of healthy adults with body temperatures that are within 2 standard deviations of the mean. So we need to use Chebyshev's theorem with k = 2.
At least 1 - 1/2^2 = 1 - 1/4 = 0.75, or 75%, of the healthy adults have body temperatures within 2 standard deviations of the mean.
To find the minimum and maximum possible body temperatures that are within 2 standard deviations of the mean, we can use the formula:
Minimum = Mean - k * Standard deviation
Maximum = Mean + k * Standard deviation
Plugging in the values for this problem, we get:
Minimum = 98.33 - 2 * 0.67 = 96.99°F
Maximum = 98.33 + 2 * 0.67 = 99.67°F
Therefore, we can say that at least 75% of healthy adults have body temperatures within the range of 96.99°F to 99.67°F.

To find f(3) using synthetic division, we need to divide the polynomial f(v) by the factor (v - 3). This will give us the quotient and the remainder, which will help us find the value of f(3).
Write the coefficients of the polynomial in a row: 12 -40 4 17 21
Write the value of the factor we are dividing by to the left of the row: 3 | 12 -40 4 17 21
Bring down the first coefficient: 3 | 12 -40 4 17 21
------------------
12
Multiply the first coefficient by the factor and write the result under the second coefficient: 3 | 12 -40 4 17 21
------------------
12 36
Add the second coefficient and the result from step 4: 3 | 12 -40 4 17 21
------------------
12 -4
Repeat steps 4 and 5 for the remaining coefficients: 3 | 12 -40 4 17 21
------------------
12 -4 0 51
The last number in the bottom row is the remainder. This is the value of f(3): 3 | 12 -40 4 17 21

The inequality (x + 2)/(x - 7)>0 can be solved algebraically by first subtracting 2 from both sides. This results in the inequality (x - 7) > 2. By dividing both sides by (x-7), the inequality can be simplified to 1>2/x-7. This simplifies further to -7>2/x, or x>-7/2. Therefore, the solution to the inequality is x>-7/2.
In plain terms, this means that a value of x must be greater than -7/2 in order for the inequality to be true. This implies that the value of x must be a number greater than -3.5, since -7/2 is the same as -3.5. Thus, if x is any number greater than -3.5, then the inequality (x + 2)/(x - 7) > 0 will be satisfied.

divided by 10 on each side
x=2
Answer:
You would use the PEDMAS rule for this equation.
First, distribute 2 inside the parentheses so the equation is 10x + 6 = 26
Then, subtract 6 from both sides 10x = 20
The answer is x = 2.

\( 7 \sqrt[3]{8 x^{2} y}+6 \sqrt[3]{x^{5} y^{4}} \) = \( 13 \sqrt[3]{x^{5} y^{4}} \)
Adding/subtracting radical expressions and simplifying can be done as follows:
(a) \( -2 y \sqrt{28 x^{3}}+3 x \sqrt{63 x y^{2}}-3 \sqrt{112 x^{3} y^{2}} \)
\(-2 y \sqrt{28 x^{3}}+3 x \sqrt{63 x y^{2}}-3 \sqrt{112 x^{3} y^{2}}\) = \( -2 y \sqrt{28 x^{3}}+3 x \sqrt{63 x y^{2}}-3 \sqrt{28 x^{3} \cdot 4 y^{2}}\)
\(-2 y \sqrt{28 x^{3}}+3 x \sqrt{63 x y^{2}}-3 \sqrt{28 x^{3} \cdot 4 y^{2}}\) = \( -2 y \sqrt{28 x^{3}}+3 x \sqrt{63 x y^{2}}-12 y \sqrt{7 x^{3}}\)
\(-2 y \sqrt{28 x^{3}}+3 x \sqrt{63 x y^{2}}-12 y \sqrt{7 x^{3}}\) = \( -14 y \sqrt{7 x^{3}}+3 x \sqrt{63 x y^{2}}\)
(b) \( 7 \sqrt[3]{8 x^{2} y}+2 \sqrt[3]{27 x^{5} y^{4}} \)
\( 7 \sqrt[3]{8 x^{2} y}+2 \sqrt[3]{27 x^{5} y^{4}} \) = \( 7 \sqrt[3]{8 x^{2} y}+2 \sqrt[3]{3^3 \cdot x^{5} y^{4}} \)
\( 7 \sqrt[3]{8 x^{2} y}+2 \sqrt[3]{3^3 \cdot x^{5} y^{4}} \) = \( 7 \sqrt[3]{8 x^{2} y}+6 \sqrt[3]{x^{5} y^{4}} \)
\( 7 \sqrt[3]{8 x^{2} y}+6 \sqrt[3]{x^{5} y^{4}} \) = \( 13 \sqrt[3]{x^{5} y^{4}} \)

Today, the sum of Caroline's age and Cameron's age is 73. 5 years ago Cameron was 2 times older than Caroline.
The answer of Caroline is 19.33 years old and Cameron is 53.67 years old
Let's start by assigning variables to represent Caroline's age and Cameron's age. We'll use C for Caroline's age and M for Cameron's age.
According to the problem, the sum of their ages today is 73, so we can write the equation:
C + M = 73
Five years ago, Cameron was 2 times older than Caroline. so we can write the equation:
M - 5 = 2(C - 5)
Now we can use the first equation to solve for one of the variables. Let's solve for C:
C = 73 - M
Next, we can substitute this value of C into the second equation:
M - 5 = 2(73 - M - 5)
Simplifying the equation gives us:
M - 5 = 146 - 2M - 10
3M = 161
M = 53.67
Now we can use this value of M to find C:
C = 73 - 53.67
C = 19.33
So Caroline is 19.33 years old and Cameron is 53.67 years old.

write an equation in point slope form for a line that passes through(-2,5) and (-1,1)
The equation of line is y = -4x - 3 and the slope is m = -4
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( -2 , 5 )
Let the second point be Q ( -1 , 1 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 1 - 5 ) / ( -1 - ( -2 ) )
On simplifying , we get
Slope m = ( -4 ) / 1
Slope m = -4
Now , the equation of line is y - y₁ = m ( x - x₁ )
y - 5 = -4 ( x - ( -2 ) )
y - 5 = -4 ( x + 2 )
y - 5 = -4x - 8
Adding 5 on both sides , we get
y = -4x - 3
Hence , the equation of line is y = -4x - 3

What is a polygon?In Mathematics, a polygon can be defined as a two-dimensional geometric figure that consists of straight line segments and a finite number of sides. Additionally, some examples of a polygon include the following:
• Triangle
• Quadrilateral
• Pentagon
• Hexagon
• Heptagon
• Octagon
• Nonagon
