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.
Solve with variables
Answer:
4
Step-by-step explanation:
Step 1:
6x + 10 + 2x = 42 Equation
Step 2:
8x + 10 = 42 Combine Like Terms
Step 3:
8x = 32 Subtract 10 on both sides
Step 4:
x = 32 ÷ 8 Divide
Answer:
x = 4
Hope This Helps :)
x = 4 and x = –4
x = 8 and x = –8
x = 16 and x = –16
The correct statement is that the solution of this equation x² – 16 = 0, is 4 and -4.
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?
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.
More about the quadratic equation link is given below.
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 :
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
Thus, the required solution is x = 4 and x = -4.
Option (B) is correct.
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.
