The numbers to represents a diver’s position in relation to the surface of the water after diving into a pool is;

-2 meter

-3.1 meter

Negative 2 and one-half meters

Given that;

A diver’s position is in the surface of the water diving into a pool.

We have to find number to represents a diver’s position in relation to the surface of the water after diving into a pool.

What is Negative number?

A number less than zero is called the negative number.

A diver’s position is in the surface of the water diving into a pool.

Since, Diving into a pool is represents negative number.

Hence, The number to represents a diver's position is in negative sign.

So, The numbers are;

⇒ -2 meter

⇒ -3.1 meter

⇒ Negative 2 and one-half meters.

Answer:

-2, -3.1, -2.5

Step-by-step explanation:

Since the diver dived into the pool, they are below the surface (assuming it is an inground pool). So the correct answers will be the negative answers.

the smaller number is 8, and the larger number is 12, and they indeed add up to 20, and three times the smaller number (3 * 8) is equal to two times the larger number (2 * 12).

Let's call the two numbers x and y, with x being the smaller number and y being the larger number.

We have two pieces of information from the problem:

1. The sum of the two numbers is twenty:

  x + y = 20

2. Three times the smaller number is equal to two times the larger number:

  3x = 2y

Now, we can solve this system of linear equations.

First, we can solve equation (1) for x:

x = 20 - y

Now, substitute this expression for x into equation (2):

3(20 - y) = 2y

Now, distribute the 3 on the left side:

60 - 3y = 2y

Now, isolate the variables on one side of the equation and constants on the other side:

60 = 2y + 3y

Combine like terms:

60 = 5y

Now, divide by 5 to solve for y:

y = 60 / 5

y = 12

Now that we have found the value of y, we can substitute it back into equation (1) to find x:

x + 12 = 20

Subtract 12 from both sides:

x = 20 - 12

x = 8

So, the two numbers are:

x = 8 (smaller number)

y = 12 (larger number)

Therefore, the smaller number is 8, and the larger number is 12, and they indeed add up to 20, and three times the smaller number (3 * 8) is equal to two times the larger number (2 * 12).

Answer:

L = ±√( (100c² - 100v²) / C² )

Step-by-step explanation:

You're just doing reverse PEMDAS.

So first get all the values correlated with L on one side and the non-L values on the other side using subtraction/addition.

Then remove all coefficient using multiplication/division.

Then take the sqareroot to get rid of the squre on the v.

Remember that taking squareroot gives a ± answer because

(x)² = (-x)²
