GREAT LEARNING TOOL MADE BY A GENIUS DUDE!!! Quizard reads your question and like searches the web for similar information to come up with an answer. Quizard provides a paragraph explanation along with the short answer. READ THOROUGHLY bc it is a computer and sometimes the wording makes it come up with “the wrong (short) answer” even though throughout the (longer paragraph) explanation you can figure out the true answer that Quizard happened to word incorrectly or chose a similar but wrong multiple choice option for. If you’re not trying using it for just the short answer not bothering to read and check the answer and dont read the paragraph then ya.. some of your answers are gonna be wrong. But if it doesn’t give you the right answer it’ll at least provide some explanation to put you on the right path.

## It always works but…

It works! I had a test to take at home and it was history test. I am bad a history and I saw this app and downloaded the app. It answered 10 questions and stopped. It said you have to pay! What the! I needed the answers! I was on Lock Screen too, so I could not just copy and pasted! Soon I found out that there is a daily reward! I got 5 or 10 more and there were 30 so I had to just the last 10. I had a 64% on that test. Soon I did a little thinking the next day and got a 72%. Best app ever!

## Do not get it’s a scam

I got this app with high hopes but it required a subscription to use. It offered a free trial so I decided I would test it out and signed up for it. This free trial was not a a week but only 3 days. Still I thought I had canceled the trial after day two but it turned out It didn’t cancel correctly because I got charged $60! This is an absurd amount, they charged the yearly subscription not the weekly or monthly and the charge is crazy! I quickly sent them a message asking if I could get a refund but after waiting almost a week I got nothing. I sent them another but still have gotten no response. This is absolutely absurd the app is not worth the money and they will steal your money in dishonest ways horrible company do not get this app!

## . Math 12 Written Homework 11 2023 Instructions: Please answer...

Answer & explanation.

Question 1: To find the exact length of the perimeter of the triangle with side lengths 2√6 cm, 2√24 cm, and √54 cm, simply add the lengths of all three sides:

Perimeter = 2√6 + 2√24 + √54

Now, let's simplify each of these square roots: √6 = √(2 * 3) = √2 * √3 √24 = √(4 * 6) = 2√6 √54 = √(9 * 6) = 3√6

Now, plug these values into the perimeter formula:

Perimeter = 2(√2 * √3) + 2(2√6) + 3√6

Perimeter = 2√6 + 4√6 + 3√6

Now, add these terms together:

Perimeter = 9√6 cm

So, the exact length of the perimeter is 9√6 cm.

Question 2: (a) Rationalize the denominator for 6/∛(3y^2): To rationalize the denominator, multiply both the numerator and denominator by the cube root of the denominator:

6/∛(3y^2) * (∛(3y^2))^2 / (∛(3y^2))^2

This simplifies to:

(6∛(3y^2)) / 3y^2

Now, divide both the numerator and denominator by 3 to simplify:

(2∛(3y^2)) / y^2

(b) Rationalize the denominator for (√5 + 4) / (2 - √5): To rationalize the denominator, multiply both the numerator and denominator by the conjugate of the denominator:

[(√5 + 4) * (2 + √5)] / [(2 - √5) * (2 + √5)]

Now, simplify both the numerator and denominator:

Numerator: (2√5 + 8 + √5) Denominator: (4 - 5)

Combine like terms in the numerator:

(3√5 + 8) / (-1)

So, the rationalized expression is:

Question 3: (a) To solve for x in the equation x - 3√(x-5) = 5, first isolate the square root term on one side:

x - 5 = 3√(x-5)

Now, square both sides to eliminate the square root:

(x - 5)^2 = (3√(x-5))^2

x^2 - 10x + 25 = 9(x - 5)

Expand and simplify:

x^2 - 10x + 25 = 9x - 45

Now, move all terms to one side to set the equation to zero:

x^2 - 10x - 9x + 25 + 45 = 0

x^2 - 19x + 70 = 0

Factor the quadratic equation:

(x - 14)(x - 5) = 0

Now, set each factor equal to zero and solve for x:

x - 14 = 0 x = 14

x - 5 = 0 x = 5

Check both solutions, but the only valid solution is x = 5.

(b) To solve for x in the equation √(2x+6) = √(7-2x) + 1, first isolate one square root term on one side:

√(2x+6) - √(7-2x) = 1

Now, square both sides to eliminate the square roots:

(√(2x+6) - √(7-2x))^2 = 1^2

Simplify the left side:

2x + 6 - 2√((2x+6)(7-2x)) + 7 - 2x = 1

Now, simplify further:

2√((2x+6)(7-2x)) = 1 - 7 + 6

2√((2x+6)(7-2x)) = 0

Now, square both sides again to eliminate the square root:

4(2x+6)(7-2x) = 0

Now, expand and simplify:

4(14x - 4x^2 - 12x + 42) = 0

4(2x^2 - 26x + 42) = 0

Divide both sides by 4:

2x^2 - 26x + 42 = 0

Now, factor the quadratic equation:

x^2 - 13x + 21 = 0

(x - 7)(x - 3) = 0

x - 7 = 0 x = 7

x - 3 = 0 x = 3

Check both solutions, but the only valid solution is x = 7.

Question 4: The distance from home plate to second base on a baseball diamond is 90 feet. To find the distance the ball travels from home to second, it travels along the hypotenuse of a right triangle, with the bases forming the other two sides. Since the bases are 90 feet apart, this forms a right-angled triangle.

By the Pythagorean Theorem, the distance traveled by the ball is:

Distance = √(90^2 + 90^2) = √(8100 + 8100) = √16200

Now, simplify the square root:

Distance = √(900 * 18) = 30√18 feet

To approximate to two decimal places:

Distance ≈ 30 * 4.2426 ≈ 127.278 feet

So, the exact distance is 30√18 feet, and the approximate distance to two decimal places is approximately 127.28 feet.

Here's a simplified explanation of each of your questions in four steps:

Question 1: Finding the perimeter of a triangle.

- Add the lengths of all three sides.
- Simplify the square roots in the side lengths.
- Combine like terms.
- The exact perimeter is 9√6 cm.

Question 2: Rationalizing denominators.

- Multiply both the numerator and denominator by the cube root of the denominator to rationalize.
- Simplify by canceling common factors.
- The rationalized expression is obtained.
- Repeat the same process for the second part of the question.

Question 3: Solving equations with square roots.

- Isolate the square root term on one side of the equation.
- Square both sides to eliminate the square root.
- Simplify and move all terms to one side.
- Factor or solve the quadratic equation to find the values of x.

Question 4: Using the Pythagorean Theorem.

- Recognize that the bases and the ball's path form a right-angled triangle.
- Apply the Pythagorean Theorem: a^2 + b^2 = c^2.
- Substitute the given distances for the bases (90 feet).
- Simplify to find the exact and approximate distance the ball travels from home to second base.
