The sets of numbers 3, 4, 5 and 8, 15, 17 are Pythagorean triples. Use what you know about the Pythagorean Theorem and explain or show why they are Pythagorean triples. Be sure to show your work for each set of triples! (5 points)

Answers

Answer 1
Pythagorean triples are 3 whole numbers which satisfy the Pythagorean theorem when they make up the sides of a right angled triangle.
For the numbers 3, 4 and 5, let 5 be the length of the hypotenuse (AC, of triangle ABC in which B is a right angle), and 4 and 3 be the lengths of the other 2 sides of the triangle (AB and AC).
According to the Pythagorean theorem,
=

25 = 9 + 16
25 = 25
Since 3, 4 and 5 satisfy the criteria, they are Pythagorean triples.
Similarly, for the numbers 8, 15 and 17, let 17 be the length of the hypotenuse (PR, of triangle PQR in which Q is a right angle), and 4 and 3 be the lengths of the other 2 sides of the triangle (PQ and QR).


289 = 225 + 64
289 = 289
Since 8, 15 and 17 satisfy the criteria, they are also Pythagorean triples.

2. You are making wooden picture
frames of different sizes but you
have limited supplies, so you are
restricting the perimeter of each
frame to 4 feet or less and the length
to exactly 1.5 feet. Find the range of
the frame width. Show your work.

Answers

The range of the frame width for the considered case is 0.5 (feet), because for this case, it can be at max of 0.5 feet, and at minimum of 0 feet.

What is the range of a particular data set?

For a set of data, the range is the difference between the maximum and minimum value. It sort of gives an idea of spread of the data.

For this case, we're given that:

Frame is rectangular (assumingly).The perimeter of the frame ≤ 4 feetThe length of the frame = 1.5 feet

Perimeter of a rectangle = 2(length + width)

Let 'l' denotes length, and 'w' denotes width, then we get:

[tex]Perimeter \leq 4\\2(l+w) \leq 4\\2(1.5 + w) \leq 4\\\\\text{Dividing both the sides by 2}\\\\1.5 + w \leq 2\\\\\text{Subtracting 1.5 from both the sides so as to get 'w' on one side}\\\\w \leq 0.5[/tex]

Now since the lowest value of width of a frame can be zero only, therefore, we get:

[tex]0 \leq w \leq 0.5[/tex]

Thus, the range of values 'w' can assume is: 0.5 - 0 = 0.5

Thus, the range of the frame width for the considered case is 0.5 (feet), because for this case, it can be at max of 0.5 feet, and at minimum of 0 feet.

Answer:

Step-by-step explanation:

Method 1

Apply Difference of Two Squares Formula: [tex]a^2-b^2=(a+b)(a-b)[/tex]

Given  [tex]x^2-16=0[/tex]

Rewrite 16 as 4²

Therefore, [tex]a^2=x^2[/tex] and [tex]b^2=4^2[/tex]

[tex]\implies a = \sqrt{x^2}=x[/tex]

[tex]\implies b=\sqrt{4^2} =4[/tex]

[tex]\implies x^2-16^2=(x+4)(x-4)[/tex]

[tex]\implies (x+4)(x-4)=0[/tex]

[tex]\implies (x+4)=0 \implies x=-4[/tex]

[tex]\implies (x-4)=0 \implies x=4[/tex]

Method 2

Given equation:

[tex]x^2-16=0[/tex]

Add 16 to both sides:

[tex]\implies x^2-16+16=0 + 16[/tex]

[tex]\implies x^2=16[/tex]

Square root both sides:

[tex]\implies \sqrt{x^2}=\sqrt{16}[/tex]

[tex]\implies x=\pm4[/tex]

Therefore, x = -4, x = 4

Answer: just graph it using the x and y coordinate points

Step-by-step explanation:

Answer:

(-4, -2)

Step-by-step explanation:

Rewrite the equations to make y the subject, so that it's easier to calculate the points on each line:

Equation 1

x - y = -2

⇒ x + 2 = y

⇒ y = x + 2

Equation 2

2x - 3y = -2

⇒ 2x + 2 = 3y

⇒ y = (2/3)x + 2/3

Calculate 2 points on each line:

Equation 1  (blue line on attached graph)

Substitute x = 0 and x = -2 into Equation 1 to create 2 points:

x = 0:   y = 0 + 2  ⇒ (0, 2)

x = -2:   y = -2 + 2  ⇒ (-2, 0)

Plot the points and draw a line through them.

Equation 2 (red line on attached graph)

Substitute x = 2 and x = -1 into Equation 1 to create 2 points:

x = 2:   y = (2/3)(2) + 2/3  ⇒ (2, 2)

x = -1:   y = (2/3)(-1) + 2/3  ⇒ (-1, 0)

Plot the points and draw a line through them.

Solution

The solution is the point where the two lines intersect.

Therefore, the point of intersection is (-4, -2)

Once you have reached the middle you should have the two numbers 14, 16. Take 14 and 16, add them together and you will get 30. Divide 30 by 2 because there is two numbers for the median. You should end with 15 as your median.

to find the mode- find the number that occurs the most in the set of numbers, in this case all numbers occur the same amount of times, so therefor there is no mode.

Step-by-step explanation:

The -2 and 2 on the right side cancel out and so you are left with 7.7-2=w. Combine like terms and your left with 5.7=w

Step 1 is done wrong

When simplifying this I would notice that one side is subtracting 2 (a rational number) and that the other also has a rational number.
To simplify this, you have to get rid of the -2 by canceling it out. You can do this by adding 2 on both sides (you have to add 2 to both sides to make sure both sides of the equal sign are equal).

So instead of subtracting 2 on one side and subtracting 2 on the other, you are supposed to add 2 to both sides.
