Whats the radical of 12?

Mathematics
1 answer:
Harrizon [31]3 years ago
4 0

Answer:

2√3

Step-by-step explanation:

So √12 is in radical form. I think what you are asking for is to reduce the expression to its **simplest** readical form.

So 12 = 4*3, √12 = √4 * √3.

So 12 = 4*3, √12 = √4 * √3.

We can ‘reduce’ this by noting that √4 =2, so the expression becomes 2√3.

This cannot be further reduced because 3 isn’t a square or divisible by a square, so 2√3 is the simplest radical form.

What is the factorization of this polynomial? 9x^2-0x-4
Harman [31]
9x²-0x-4
=9x²-4
=(3x-2)(3x+2) is the factor form of 9x²-0x-4
Solve for x:
3x-2=0
Add 2 to each side
3x-2+2=0+2
3x=2
Divided 3 to each side
3x/3=2/3
x=2/3
Or
3x+2=0
Subtract 2 to each side
3x+2-2=0-2
3x=-2
Divided 3 to each side
3x/3=-2/3
x=-2/3. Hope it help!

The CPU of a personal computer has a lifetime that is exponentially distributed with a mean lifetime of six years. a) What is th
amm1812

Answer: Our required probability is 0.39.

Step-by-step explanation:

Since we have given that

X be the exponentially distributed with mean life = 6 years

So, E[x]=6

\dfrac{1}{\lambda}=6\\\\\lambda=\dfrac{1}{6}

So, our cumulative distribution function would be

F(x)=1-e^{-\lambda x}

We need to find the probability that the CPU fails within 3 years.

P(X

Hence, our required probability is 0.39.

How do you find the f(x) inverse using fractions?
fenix001 [56]
For example.. 1) switch places of x and y. x=3y+1 x=3 y +1
2) try to solve for y. so multiply the denominator by x to get rid of it
3) after multiplying, ur left with xy+x=3 x y + x=3
4) that converts to 2xy= x y =3
5) get rid of 2x on left by placing it on the right
6) convert y to inverse function

The first five terms of an arithmetic sequence are shown below: 20, 17, 14, 11, 8, . . . Let n represent the term number and f(n
Leona [35]

Answer: 17 -3n

Explanation:

In the given arithmetic progression 20,17,14,11,8....

first term that is a = 20

common difference that  is d=  a2-a1 = 17-20 = -3

let n is the nth term

a_{n} = a+(n-1)d

substituting the values of first, common,difference and n

a_{n} =20+(n-1) (-3)

                        = 20 -3n+3

                         =23 -3n
