In this right triangle, what is the length of the unknown side?

Answers

Answer:

√104 in

Step-by-step explanation:

Well to start off we can use Pythagorean's theorem ~ A^2 + B^2 = C^2

in this case we will indirectly use this formula. Now we know this; A^2 + 11^2 = 15^2

Let's start using some algebra now B )

A^2 + 121 = 225 > A^2 = 225 - 121 > A^2 = 104 > A = √104

Which is the answer. ALso if you're the brainy type and want to know how to simplify this even further...

Can the Square Root of 104 Be Simplified?

104 can be simplified only if you can make 104 inside the radical symbol smaller. This is a process that is called simplifying the surd. In this example, the square root of 104 can be simplified.

√104 = 2√26.

There is only 1 true solution to the equation. The zeros of 0 = x2 – 5x 6 are possible solutions to the radical equation.

Answers

You can square both the sides and then use the formula for finding the roots of the obtained quadratic equation to find the solution needed.

The statements describing the solutions to the given equations are

Option C: x = 3 is a true solution.Option E: The zeroes(also called solutions) of [tex]x^2 - 5x + 6 = 0[/tex] are possible solutions to the radical equation.

How to find the solutions to a quadratic equation?

Let the quadratic equation be [tex]ax^2 + bx + c = 0[/tex]

Then the solution to this quadratic equation is given as

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

What are extraneous  solutions?

Those values of the variables who come out behaving like solutions but when tested, doesn't get proved as solutions to the given equation are called extraneous solutions.

Using that above conclusion to find the solutions to the given equation

Solutions to an equation means those values of the unknown for which the equation is true.

The given equation is

[tex]\sqrt{x-2} -4 = x - 6[/tex]

Converting that equation to quadratic form, we get

[tex]\sqrt{x-2} -4 = x - 6\\\\\sqrt{x-2} = x - 2\\[/tex]

From the obtained equation, we can see that x-2 is such a number whose square root is it itself. It is true for 2 numbers only.

First 1, and second 0.

Putting these values, we get

[tex]x-2 = 1\\x = 2+1 = 3\\\\x-2 = 0\\x = 2[/tex]

Thus, there are two solutions to the given equation. They are x = 2, and x = 3

Testing both the solutions by putting them in the given equation.

Case 1: x = 2

[tex]\sqrt{x-2} -4 = x - 6\\\sqrt{2-2} - 4 = 2 - 6\\0-4 = -4\\-4 = -4[/tex]

This is correct equality, thus, x = 2 is a correct solution.

Case 2: x = 3

[tex]\sqrt{x-2} -4 = x - 6\\\\\sqrt{3-2} - 4 = 3 - 6\\1 - 4 = -3\\-3 = -3[/tex]

This is correct equality, thus, x = 3 is a correct solution.

The zeroes(also called solutions) of [tex]x^2 - 5x + 6 = 0[/tex] is found as:

[tex]x^2 - 5x + 6 = 0\\x^2 - 3x - 2x +6 = 0\\(x-2)(x-3) = 0\\x = 2, x = 3[/tex]

Thus, the The zeroes(also called solutions) of [tex]x^2 - 5x + 6 = 0[/tex]  are possible solutions to the radical equation given.

Thus,

Option C: x = 3 is a true solution.Option E: The zeroes(also called solutions) of [tex]x^2 - 5x + 6 = 0[/tex] are possible solutions to the radical equation.

Approximate answer: [tex]x \approx 12.2577[/tex]

====================================================

How to find the answer:

Focus on the largest triangle. It appears to be a right triangle. If so, then we can use the pythagorean theorem to get the following:

[tex]a^2 + b^2 = c^2\\\\a^2 + 12^2 = 13^2\\\\a^2 + 144 = 169\\\\a^2 = 169 - 144\\\\a^2 = 25\\\\a = \sqrt{25}\\\\a = 5[/tex]

The horizontal leg of the largest right triangle is 5 units long.

The identical single tickmarks tell us that the horizontal leg is cut into two smaller pieces of equal length.

Each smaller piece is 5/2 = 2.5 units long.

------------------------------

Now focus on the smaller skinny right triangle with legs a = 2.5, b = 12 and hypotenuse c = x.

Use the pythagorean theorem again to find the hypotenuse x.

[tex]2.5^2 + 12^2 = c^2\\\\6.25 + 144 = x^2\\\\150.25 = x^2\\\\x^2 = 150.25\\\\x = \sqrt{150.25}\\\\x = \sqrt{\frac{601}{4}}\\\\x = \frac{\sqrt{601}}{\sqrt{4}}\\\\x = \frac{\sqrt{601}}{2}\\\\x \approx 12.2577[/tex]

[tex]q(x) = -5(x +10)^2 -1[/tex]

[tex]t(x) = -2x^2 - 4x - 3[/tex]

Thus the option B and E is correct.

What is transformation of a function?

Transformation of a function is shifting the function from its original place in the graph.

Types of transformation-

Horizontal shift- Let the parent function is [tex]f(x)[/tex]. Thus by replacing parent function with [tex]f(x-b)[/tex] shifts the graph b units right and by replacing parent function with [tex]f(x+b)[/tex] shifts the graph b units left.

Vertical shift- Let the parent function is [tex]f(x)[/tex]. Thus by replacing parent function with [tex]f(x)-c[/tex] shifts the graph b units down and by replacing parent function with [tex]f(x)+c[/tex] shifts the graph b units up.

Given information-

The given function in the problem is,

[tex]f(x)=x^2[/tex]

The functions have a maximum and are transformed to the left and down of the parent function.

In the option B the function is shifted 10 units left and 1 units down as,

[tex]q(x) = -5(x +10)^2 -1[/tex]

Thus the option B is the correct option.

In the option E the function is shifted 1 units left and 2 units down as,

[tex]t(x) = -2x^2 - 4x - 3\\t(x)=-2x^2 - 4x - 1-2\\t(x)=-2(x+1)^2-2[/tex]

Thus the option E is the correct option.

Hence, the functions have a maximum and are transformed to the left and down of the parent function are,

[tex]q(x) = -5(x +10)^2 -1[/tex]

[tex]t(x) = -2x^2 - 4x - 3[/tex]

Thus the option B and E is correct.

Answer:

Step-by-step explanation:

y = mx + b.y = 15/13x − 10/13

Answer:

The answer is y = 15x/13 – 10/13.

Step-by-step explanation:

We are given equation

15x – 13y = 10

Now, The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

y = mx + b

Rewrite in slope-intercept form.

15x – 13y = 10

Subtract 15x from both sides of the equation we get,

15x – 15x – 13y = 10 – 15x

-13y = 10 – 15x

Divide each term by -13 and simplify.

-13y/(-13) = 10 – 15x ÷ (-13)

Cancel the common factor of -13

y = -10/13 + 15x/13

Now, Rearrange it

y = 15x/13 – 10/13

Thus, The answer is y = 15x/13 – 10/13.

What amount of water should be mixed with 1 liter of 14% bleach?

The amount of water should be mixed with 1 liter of 14% bleach solution,

we know that the water will have 0% bleach. thus, the amount of water we need to mix with the 14% bleach solution is (2/5) liters.

Therefore, the ratio of water and bleach solution can be written as,

[tex]\rm \dfrac{14\%\ solution}{Water} = \dfrac{5}{2}[/tex]

What amount of water should be mixed with 18 liters of 14% bleach?

We know the ratio of water and bleach solution that should be mixed to form a 10% concentration bleach is (5/2), therefore, we will use the same ratio,

[tex]\rm \dfrac{14\%\ solution}{Water} = \dfrac{5}{2}[/tex]

[tex]\rm \dfrac{18}{Water} = \dfrac{5}{2}\\\\\rm {Water} = \dfrac{18\times 2}{5}\\\\\rm Water = 7.2\ liters[/tex]

Elizabeth has a swimming pool at home. She wants to build a deck all the way around her rectangular swimming pool. The width of her swimming pool is 8 feet and the length is 10 feet. If she has enough wood to build a deck that is 280ft, how wide can she make the deck?

Answers

Using the perimeter of a rectangle, it is found that she can make a deck of 122 ft wide.

What is the perimeter of a rectangle?

The perimeter of a rectangle of length l and width w is given by:

[tex]P = 2(l + w)[/tex]

In this problem:

She has enough wood to build a deck that is 280ft, hence P = 280.The length is of 10 feet, hence l = 10.Considering that the deck's width will be added to the actual width of 8 feet, we have that w = 8 + w.

Then:

[tex]P = 2(l + w)[/tex]

[tex]280 = 2(10 + 8 + w)[/tex]

[tex]36 + 2w = 280[/tex]

[tex]2w = 244[/tex]

[tex]w = \frac{144}{2}[/tex]

M = (72 + 80 + 74 + 76 + 76 + 79 + 78 + 73 + 79 + 68 + 70)/11 = 75"

For the basketball team, it is given by:

M = (78 + 79 + 79 + 80 + 76 + 77 + 77 + 76 + 77 + 74 + 74)/11 = 77"

The difference is the subtraction of the means, hence:

x + x + 15 + 3x + 45 = 245 , that is

5x = 185 ( divide both sides by 5 )

x = 37

The plan for the Thorne’s backyard play area, shaped like a trapezoid, is shown. The area of the play area is 286.56 square feet. A border is planned around the perimeter of the play area. How many feet of material are needed for the border?

Answers

The length of material needed for the border is the perimeter of the backyard play area

How to calculate the length of material needed

The area of the play area is given as:

[tex]Area = 286.56[/tex]

The area of a trapezoid is calculated using:

[tex]Area = 0.5 * (L1 + L2) * H[/tex]

Where L1 and L2, are the parallel sides of the trapezoid and H represents the height.

The given parameter is not enough to solve the length of material needed.

So, we make use of the following assumed values.

Assume that the parallel sides are: 25 feet and 31 feet long, respectively.

While the other sides are 10.2 feet and 8.2 feet

The length of material needed would be the sum of the above lengths.

So, we have:

[tex]Length = 25 + 31 + 10.2 + 8.2[/tex]

[tex]Length = 74.4[/tex]

Using the assumed values, the length of material needed for the border is 74.4 feet
