Find geometric mean between 3 and 6

2 answers:

4 0

Call the geometric mean ' G '.

Then (3 / G) = (G / 6)

This is a proportion, and may be "cross-multiplied":

G² = 18

G = √18 = about 4.2426... (rounded)

$geometric\ mean\ between \ a\ and\ b\ = \sqrt{a\cdot b} \\----------------------\\\\geometric\ mean= \sqrt{3\cdot6} = \sqrt{3\cdot3\cdot2} =3\cdot \sqrt{2}$

What is the prime factorization of 240? Question options: 24 · 3 · 7 23 · 3 · 5 24 · 5 23 · 5 · 7 24 · 3 · 5

The prime factorization of 240 is $2^{4}$ . 3 . 5 ⇒ last answer

Step-by-step explanation:

Prime number is the number that has only 2 factors 1 and itself

{2 , 3 , 5 , 7 , 11 , 13 , 17 , 19 , 23 , 29 , ............}

In prime factorization we use only the prime numbers

Ex: The factors of 15 are 1 , 3 , 5 , 15,

Then the prime factors of 15 are 3 and 5 only because they are

prime numbers

So to find the prime factors of a number do that

1. Factorize the number by divide it using prime numbers only

2. Write the number as a product of its prime factors

∵ 240 divisible by first prime number 2

∴ 240 ÷ 2 = 120

∵ 120 ÷ 2 = 60

∵ 60 ÷ 2 = 30

∵ 30 ÷ 2 = 15

- We divided the number by 2 for 4 times

∴ $2^{4}$ is a prime factor of 240

∵ 15 is divisible by prime number 3

∴ 15 ÷ 3 = 5

∴ 3 is a prime factor of 240

∵ 5 is divisible by prime number 5

∴ 5 ÷ 5 = 1

∴ 5 is a prime factor of 240

∴ The prime factors of 240 are $2^{4}$ , 3 , 5

The prime factorization of 240 is $2^{4}$ . 3 . 5

Break down every term into prime factors. ...Look for factors that appear in every single term to determine the GCF. ...Factor the GCF out from every term in front of parentheses, and leave the remnants inside the parentheses. ...Multiply out to simplify each term.

Use the function below to find F(1). F(t) = 2•1/2^3t

stiv31 [10]

Answer:

D) 1/4

Step-by-step explanation:

To solve this, first lets figure out what this variable is. We know we must multiply by t. Well, looking at it, we know that t is one. So lets plug that in.

2*1/2^3(1)

Now we need to figure out what the exponent is that 2 will be raised to. To find that, find out what 3 times one is.

2*1/2^3

Now we need to solve the exponent.

2*1/8

Remember, 2 cubed is eight.

Now we need to find out what 2*1/8 is. To solve this more easily, I am going to turn two into a fraction. This will give us 2/1*1/8. Now we cross multiply, multiplying the numerators by the numerators, and the denominators by the denominators. Remember, the numerator is the top number, and the denominator is the bottom number.

If we do that, we get:

2/8

If we simplify it, we get 1/4. So the asnwer is D) 1/4
