Which of these do you prove with a geometric proof? Select one of the options below as your answer:. . A.. experiments. B.. opinions. C.. postulates. D.. theorems.

Answers

Answer with explanation:

A.→Experiment

In Experiments we do not require basic geometrical equipment.While doing experiment, to find the value of g, we use string, cork to find value of g(Acceleration due to gravity).We use different locations, to check whether value of g is same or it differs.There is no geometric proof required.

B.→Opinions

In opinion we use our senses to answer.Someone has better sense, he or she can provide better opinion on that issue ,where opinion is being taken.So,there is no geometrical use or geometric proof required while taking or forming opinion.

C:→Postulates

are the mathematical truths which do not require any proof.They are universally true statement which is used for proving other mathematical statement.

D: →Theorems

While dealing with areas and volumes of fields and different solid, we use theorems so, that things can be calculated or evaluated in more appropriate way.So, to prove theorems we require things which we call geometrical equipment.While dealing with theorems we use geometrical proof in which geometrical equipment like compass, ruler,set Square is required.

(D)We can prove THEOREMS with geometric rules........

If Walt can paint 25 feet of fence in an hour, and Joe can paint 35 feet in an hour, howmany minutes will it take them to paint a 150-foot fence, if they work together?

Answers

If Walt paints 25 ft. on one hour, and Joe pairs 35 ft in an hour, then they paint 60 ft per hour together. So, 60ft divided into the 150 ft fence equals 2 1/2 hours.

It will take Walt & Joe 2 1/2 hours to paint a 150ft fence.

The answer is 2 and a half hours

What are the solutions to the quadratic equation x2 – 16 = 0?x = 2 and x = –2
x = 4 and x = –4
x = 8 and x = –8
x = 16 and x = –16

Answers

The correct statement is that the solution of this equation x² – 16 = 0, is 4 and -4.

What is a quadratic equation?

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation. The general form of the quadratic equation is ax² + bx + c = 0

Given

The quadratic equation x² – 16 = 0

To find

The root of the quadratic equtaion?

How do find the solutions to the quadratic equation?

The quadratic equation x² – 16 = 0

We know the formula,

a² - b² = ( a - b ) ( a + b )

Then

x² – 4² = 0

(x - 4)(x + 4) = 0

x = 4 and -4

Thus, the solution of this equation x² – 16 = 0, is 4 and -4.

Answer: The correct option is (B) x = 4 and x = -4.

Step-by-step explanation: We are given to find the solutions to the following quadratic equation :

$x^2-16=0~~~~~~~~~~~~~~~~~~~~~(i)$

Since the coefficient of x is zero in the given equation, so we will be using the method of square root to solve the equation.

From equation (i), we have

$x^2-16=0\n\n\Rightarrow x^2=16\n\n\Rightarrow x=\pm√(16)~~~~~~~\textup{[taking square root on both sides]}\n\n\Rightarrow x=\pm4\n\n\Rightarrow x=4,~-4.$

Thus, the required solution is x = 4 and x = -4.

Option (B) is correct.

The fastest elevators in the Burj Khalifa can travel 330 feet in just 10 seconds. How far does the elevator travel in 12 seconds?

Answers

Answer:

The elevator will travel 396 feet in 12 seconds.

Step-by-step explanation:

10 secs = 330ft

330/10 = 33

10 * 33 = 330

Hence,

12 * 33 = 396

12 secs = 396 ft

Hope this helps :)

Answer:

The answer is 396 feet per second.

Step-by-step explanation:

1) If it travels 330 feet in 10 seconds: 330 divided by 10 = 33 feet per second.

2) It travels at 33 feet per second, for 12, seconds, so then you just need to multiply 33 x 12, to get 396 feet per second, and that's your answer.
