Two sides of an obtuse triangle measure 12 inches and 14 inches. The longest side measured 14 inches what is the gratest possible whole number length of the unknown side

Answers

Answer 1

Answer:

26

Step-by-step explanation:

If the sides of a triangle are a, b, and c, the triangle inequality theorem tells us, about the sides possible to make up this NON-right triangle:

a + b > c

b + c > a and

a + c > b

Since we have 2 sides, we will call the third unknown side x.  Let a = 12 and b = 14:

12 + 14 > x

14 + x > 12 and

12 + x > 14.

The first inequality, solved for x, is that x < 26.

The second inequality, solved for x, is that x > -2.  We all know that the 2 things in math that will never EVER be negative are distance/length measures and time; therefore, we can safely disregard -2 as a side length of this, or ANY, triangle.

The third inequality, solved for x, is that x > 2.

We now have the solutions for the side length possibilities:

2 < x < 26

From this inequality statement, we see that the longest the side could possibly be and still make a triangle with the other 2 side lengths given, is 26

Answer 2

Answer:

C. 7 inches

Step-by-step explanation:

The Obtuse Triangle Inequality Theorem: c^2 > a^2 + b^2.

14^2 > 12^2 + b^2.

196 > 144 + b^2.

so b < 52. and the square root of 52 is 7.

Thank you and have a great day!

Determine the principal value of the function: Arc sin(square root of 3/2)

Answers

Answer:

π/3

Step-by-step explanation:

We have to find the principal value of [tex]\text{arc sin}(\frac{\sqrt{3}}{2} )[/tex]

arc sin means sin inverse. The sin inverse is a one to one function with its range between [tex]-\frac{\pi}{2} \textrm{ to } \frac{\pi}{2}[/tex]

The principal value of the arc sin will lie within the above given range.

value of sin (60) or sin([tex]\frac{\pi}{3}[/tex]) is [tex]\frac{\sqrt{3}}{2}[/tex].

[tex]\frac{\pi}{3}[/tex] lies between [tex]-\frac{\pi}{2}\textrm{ and } \frac{\pi}{2}[/tex]

So, from here we can say that the Principal Value of Arc sin(square root of 3/2) is π/3

The principal value of the function Arc sin(√3/2) is,

⇒ π / 3

We have to given that,

⇒ Arc sin (√ 3/ 2)

Since, Value of arc sin lies between - π/2 and π/2.

Hence, The principal value of the function Arc sin(√3/2) is,

⇒ Arc sin(√3/2)

⇒ Arc sin(sin π/3)

⇒ π / 3

Therefore, The principal value of the function Arc sin(√3/2) is,

Charlie entered an elevator and ride up 10 floors and then down 2 floors before realizing he had not pressed the button for Floor 1. He then pressed the button for Floor 1 and rode down 14 floors and exited the elevator on Floor 1. On which floor did he begin?

Answers

Answer:

Floor 7

Step-by-step explanation:

He entered the elevator on floor x.

Then he rode up 10 floors. Now he is on floor x + 10.

Then he rode down 2 floors. Now he is on floor x + 10 - 2 = x + 8.

Then he pressed the Floor 1 button and rode down 14 floors to Floor 1. Now he is on floor x + 8 - 14 = x - 6 which is the same as Floor 1.

Floor x - 6 is the same as Floor 1, so we get the equation:

x - 6 = 1

Add 6 to both sides:

x = 7

Since we let x be the floor number he entered the elevator in, he entered the elevator on Floor 7.

Answer:

He began on floor 7

Step-by-step explanation:

This is a question where you have to use the question from the end and work your way backwards if that makes sense.

He had to go down 14 floors to get to floor 1. So 14 + 1 = 15. He was on the 15th floor.

Next he went down 2 floors. Since this is reverse, add two floors to the answer. 15 + 2 = 17. He was on the 17th floor.

And finally, he goes up 10 floors. Doing this in reverse, take away 10 floors to the answer. 17 - 10 = 7

He started on the 7th floor.

Now to make sure it is correct, start from 7 and follow the original order of the question.

7 + 10 = 17

17 - 2 = 15

15 - 14 = 1

Which products result in a perfect square trinomial? Check all that apply. (–x + 9)(–x – 9) (xy + x)(xy + x) (2x – 3)(–3 + 2x) (16 – x2)(x2 – 16) (4y2 + 25)(25 + 4y2)

Answers

Answer:

(xy + x)and (xy + x)

(2x - 3) and (-3 + 2x)

(4y² + 25) and (25 + 4y²)

Step-by-step explanation:

* Lets explain the meaning of the perfect square trinomial

- If a binomial multiply by itself, then the answer will be a perfect

 square trinomial

- Example: if the binomial (ax + b) multiply by itself, then

 (ax ± b)(ax ± b) = (ax)(ax) ± (ax)(b) ± (b)(ax) + (b)(b)

 (ax + b)(ax + b) = (ax)² ± 2(axb) + (b)²

∵ (ax + b)(ax + b) = (ax + b)²

∴ (ax ± b)² = (ax)² ± 2(axb) + (b)² ⇒ perfect square trinomial

* From the example above the perfect square trinomial has 3 terms

# 1st term is the square the first term in the binomial

# 2nd term is twice the product of the two terms of the binomial

# 3rd term is the square of the second term of the binomial

* Lets solve the problem

- The product of (-x + 9)and (-x - 9)

∵ -x + 9 ≠ -x - 9

∴ The product of (-x + 9) and (-x - 9) is not a perfect square trinomial

- The product of (xy + x)and (xy + x)

∵ xy + x = xy + x

∴ (xy + x)(xy + x) = (xy + x)²

∵ (ax ± b)² = (ax)² ± 2(axb) + (b)² ⇒ perfect square trinomial

∴ The product of (xy + x) and (xy + x) is a perfect square trinomial

- The product of (2x - 3) and (-3 + 2x)

∵ (-3 + 2x) can be written as (2x - 3)

∴ 2x - 3 = -3 + 2x

∴ (2x - 3)(-3 + 2x) = (2x - 3)²

∵ (ax ± b)² = (ax)² ± 2(axb) + (b)² ⇒ perfect square trinomial

∴ The product of (2x - 3)(-3 + 2x) is a perfect square trinomial

- The product of (16 - x²) and (x² - 16)

∵ 16 - x² can be written as -x² + 16

- If we take -1 common factor from -x² + 16

∴ -x² + 16 = -(x² - 16)

∴ (-x² + 16)(x² - 16) = -(x² - 16)(x² - 16) = -(x² - 16)²

∵ (ax ± b)² = (ax)² ± 2(axb) + (b)² ⇒ perfect square trinomial

∵ -(x² - 16)² = -(x^4 - 32x² + 256) = -x^4 + 32x² - 256

∵ x^4 - 32x² + 256 is perfect square trinomial

∵ -x^4 + 32x² - 256 is not a perfect square trinomial

∴ The product of (16 - x²) and (x² - 16) is not a perfect square trinomial

- The product of (4y² + 25) and (25 + 4y²)

∵ 25 + 4y² can be written as 4y² + 25

∴ 4y² + 25 = 25 + 4y²

∴ (4y² + 25)(25 + 4y²) = (4y² + 25)²

∵ (ax ± b)² = (ax)² ± 2(axb) + (b)² ⇒ perfect square trinomial

∴ The product of (4y² + 25) and (25 + 4y²) is a perfect square trinomial

Find the arc length intercepted by a central angle of radians in a circle whose radius is 18.4 inches. 13.8π 15.2π 24.5π

Answers

Final answer:

The arc length intercepted by a central angle of π radians in a circle of radius 18.4 inches is calculated as arc length = θ × radius, resulting in 18.4π inches.

Explanation:

To find the arc length intercepted by a central angle of θ radians in a circle with radius r, we use the formula:

arc length (s) = θ × r

Given that the central angle θ is π radians and the radius r is 18.4 inches, we can compute the arc length as follows:

arc length (s) = π × 18.4 inches

By multiplying, we get:

arc length (s) = 18.4π inches

Therefore, the arc length intercepted by a central angle of π radians in a circle with a radius of 18.4 inches is 18.4π inches.

A right triangle has one angle that measure 23o. The adjacent leg measures 27.6 cm and the hypotenuse measures 30 cm. What is the approximate area of the triangle? Round to the nearest tenth.

Check the picture below.

To find the area of the right triangle with a given hypotenuse and adjacent leg, use the Pythagorean theorem to calculate the other leg. Then, use the base and height (the two legs) in the area formula for a right triangle. The area of the triangle is approximately 148.7 cm².

To find the area of a right triangle, you need two perpendicular sides, known as the legs of the triangle. Since we are given the hypotenuse (30 cm) and one adjacent leg (27.6 cm) which is one of the legs, we need to find the other leg. Using the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b).

In mathematical terms, this is expressed as a² + b² = c². Therefore, the length of the other leg (b) can be found using the equation b² = c² - a², where c is the hypotenuse and a is the given adjacent leg.

Substituting the given values, we have b² = 30² - 27.6². Calculating this gives b ≈ 10.8 cm.

Now, the area of the triangle can be calculated using the formula for the area of a right triangle, which is (1/2) × base × height. In this case, the base and height are the two legs of the triangle. Substituting the lengths of the legs we have, Area ≈ (1/2) × 27.6 cm × 10.8 cm. The result is approximately 148.7 cm², which is the area of the triangle rounded to the nearest tenth.
