Answer:

x=25.1

Step-by-step explanation:

by using Pythagorean theorem, [tex]a^{2} +b^{2}=c^{2}[/tex] where c is the hypotenuse

[tex]18.15^{2}[/tex]= 329.4225

[tex]17.39^{2}[/tex]= 302.4121

since those two side lengths are the legs, the sum of the numbers is the length of the hypotenuse squared

therefore, 631.8356 (the sum) = [tex]c^{2}[/tex]

by taking the square root of 631.8356, you will get approx 25.1 for the hypotenuse (aka x)

By Pythagoras Hypotenuse for 1.   9.43 , 2.   9.22 , 3.    9.85 , 4.   12.37, 5.   14.87 , 6.   10.63

7. 9.85 ,   8. 13.04 ,  9. 19.85 ,  10.    7.81

The Pythagorean theorem, commonly referred to as Pythagoras' theorem, is a key relationship in Euclidean geometry between a right triangle's three sides. It declares that the hypotenuse's square, which is the side that is opposite the right angle, is equal to the sum of the squares of the other two sides. In other words, if the hypotenuse is length c and the legs of a right triangle are lengths a and b, then a² + b² = c².

The Pythagorean theorem, which asserts that the square of the hypotenuse is equal to the sum of the squares of the other two sides, can be used to determine the hypotenuse of a right triangle.

This theorem allows us to calculate the hypotenuse value for each of the right triangles presented as follows:

1. a = 5, b = 8

  c = √(a² + b²) = √(5² + 8²) = √(25 + 64) =√(89) ≈ 9.43

2. a = 6, b = 7

  c = √(a² + b²) = √(6² + 7²) = √(36 + 49) = √(85) ≈ 9.22

3. a = 4, b = 9

  c = √(a² + b²) = √(4² + 9²) = √16 + 81) = √(97) ≈ 9.85

4. a = 3, b = 12

  c =√(a² + b²) = √(3² + 12²) = √(9 + 144) = √(153) ≈ 12.37

5. a = 11, b = 10

  c = sqrt(a^2 + b^2) = sqrt(11^2 + 10^2) = sqrt(121 + 100) = sqrt(221) ≈ 14.87

6. a = 8, b = 7

  c = √(a² + b²)= √(8² + 7²) = √(64 + 49) = √(113) ≈ 10.63

7. a = 9, b = 4

  c =√(a² + b²)=√(9² + 4²) = √(81 + 16) = √(97) ≈ 9.85

8. a = 7, b = 11

  c = √(a² + b²)= √(7² + 11²) = √(49 + 121) ≈√(170) ≈ 13.04

9. a=13,b=15

  c=√(a² + b²)=√((13²)+(15²))=√((169)+(225))=√(394))≈19.85

10.a=5,b=6

  c=√(a²+b²)=sqrt((5²)+(6²))=s√((25)+(36))=√(61))≈7.81

The unit for the coefficient k would be dollars per unit of length squared.

To find the units for the coefficient k in the formula C = klw, we need to analyze the units of each variable.

C represents the cost of the home, which is measured in dollars.

l represents the length of the home, which is measured in some units of length, such as feet or meters.

w represents the width of the home, which is also measured in some units of length, such as feet or meters.

Therefore, we can determine the units for k by analyzing how the units for C, l, and w combine in the formula C = klw.

Starting with the left-hand side of the equation, we know that C represents dollars.

On the right-hand side of the equation, we have k times l times w. To determine the units of k, we need to figure out what units would make the entire right-hand side of the equation equal to dollars.

Since we are multiplying three quantities (k, l, and w), the units of k must cancel out the units of length in l and w in order to leave us with units of dollars.

This means that the units of k must be dollars per unit of length squared. We can write this as:

k = $/length^2

So, the units for the coefficient k in the formula C = klw are dollars per unit of length squared.

Step-by-step explanation:

There are multiple ways to do this,

  Here is ONE way

This is a RIGHT triangle, so you can use the Pythagorean theorem

  c^2 = a^2 + b^2    

      where c = hypotenuse ( long side) and a and b are the other two sides (legs)

So for this triangle :

15^2  =   x^2 + 12^2

When six integers are chosen from the set A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, there must be at least one pair of integers that adds up to 11. This can be proven using a proof by contradiction.

To solve this problem, we can use a proof by contradiction. We assume that there are six integers chosen from A such that no two integers add up to 11.

If there is no pair of integers in the six chosen that sum up to 11, then we can consider the pairs of integers (1,10), (2,9), (3,8), (4,7), and (5,6). These are the only possible pairs of integers in A that add up to 11.

However, since there are five pairs and we can choose at most one integer from each pair, we can choose at most five integers in total. This is a contradiction since we were asked to choose six integers from A. Therefore, our assumption that there are no pairs of integers that add up to 11 is false.

Hence, we conclude that there must be at least one pair of integers among the six chosen that adds up to 11.

Step-by-step explanation:

the points we plotted are (-6, -1/2), (-4, 1/2), (0, -1/5), (3, 1/2), and (6, 1/5).

What is function?

a function is a relationship or expression involving one or more variables.  It has a set of input and outputs.

To find the x-intercepts, we set the numerator of the function equal to zero:

[tex]2 / (x^2 + 3x - 10) = 0[/tex]

This is only true if the numerator is equal to zero, so:

2 = 0

This is not possible, so the function has no x-intercepts.

To find the vertical asymptotes, we look for values of x that make the denominator equal to zero:

[tex]x^2 + 3x - 10 = 0[/tex]

We can factor the quadratic as:

(x + 5)(x - 2) = 0

This means that the function has vertical asymptotes at x = -5 and x = 2.

Now, let's plot some points between and beyond each x-intercept and vertical asymptote:

When x = -6, f(x) = 2 / (-6)² + 3(-6) - 10 = -1/2

When x = -4, f(x) = 2 / (-4)² + 3(-4) - 10 = 1/2

When x = 0, f(x) = 2 / (0)² + 3(0) - 10 = -1/5

When x = 3, f(x) = 2 / (3)² + 3(3) - 10 = 1/2

When x = 4, f(x) = 2 / (4)² + 3(4) - 10 = -1/2

When x = 6, f(x) = 2 / (6)² + 3(6) - 10 = 1/5

The value of angle G for both kites are respectively:

∠G = 110°

∠G = 80°

In a kite, the angles between the two non- congruent sides usually have the same angle size. Thus:

∠E ≅ ∠G

In a quadrilateral, the sum of the inner angles is 360 degrees. Thus:

100 + 40 + ∠E + ∠G = 360

140 + 2(∠G) = 360

2(∠G) = 360 - 140

(∠G) = 220/2

∠G = 110°

Similarly, for the second kite:

∠G = 360 - (110 + 60 + 110)

∠G = 80°

The foci of the ellipse are at (0, -2√11) and (0, 2√11).

To find the foci of the ellipse with equation x²/144 + y²/100 = 1, we need to use the standard form of the equation of an ellipse:

(x - h)²/a² + (y - k)²/b² = 1

where (h, k) is the center of the ellipse, a is the distance from the center to the vertices in the x-direction, and b is the distance from the center to the vertices in the y-direction.

First, let's rewrite the given equation in standard form by dividing both sides by the constant on the right-hand side:

x²/144 + y²/100 = 1

x²/12² + y²/10² = 1

Comparing this with the standard form, we can see that the center of the ellipse is (0, 0), a = 12, and b = 10.

Thus, the distance from the center to each focus is given by c, where:

c² = a² - b²

c² = 12² - 10²

c² = 144 - 100

c² = 44

c = √44

c = 2√11 units

Thus, the distance from the center to each focus is 2√11.

Since the center is at (0, 0), the foci are located at (0, -2√11 and (0, 2√11).
