the answer would be= -2fx+3x^2+15+a/fx
Answer:
Discrete probability distribution
Step-by-step explanation:
A weighted average <em>of</em><em> </em><em>the</em><em> </em><em>possible</em> values that random a valuable can take
Answer:
B
Step-by-step explanation:
![\sqrt[4]{2x^2} *\sqrt[4]{2x^3} =(2x^2)^{1/4}*(2x^3)^{1/4}\\= 2^{1/4}*(x^2)^{1/4} *2^{1/4} * (x^3)^{1/4}\\](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2x%5E2%7D%20%2A%5Csqrt%5B4%5D%7B2x%5E3%7D%20%3D%282x%5E2%29%5E%7B1%2F4%7D%2A%282x%5E3%29%5E%7B1%2F4%7D%5C%5C%3D%202%5E%7B1%2F4%7D%2A%28x%5E2%29%5E%7B1%2F4%7D%20%2A2%5E%7B1%2F4%7D%20%2A%20%28x%5E3%29%5E%7B1%2F4%7D%5C%5C)
combine like terms
these steps use exponent laws
a few key ones i used:
(x^y^z) = x^(y*z)
x^y * x^z = x^(y+z)
let me know if you have any questions!
The sets for each of the given numbers are:
- 6426: Real, rational, integer and whole.
- √7: Real and irrational.
- 2π: Real and irrational.
- 4.0: Real, rational, integer, whole.
- √(25/36): Real and rational.
- -√16: Real, rational, and integer.
- -35: Real, rational, and integer.
- -31.8: Real and rational.
<h3>
To which set each number belong?</h3>
Here we need to identify 3 sets
- Rational numbers: all of these that can be written as a quotient of two integers.
- Irrational numbers: all of these that can't be written as a quotient of two integers.
- Integers: Any number that can be got by adding or subtracting ones.
- Whole numbers: All the integers equal or larger than 0.
- Real number: any of the above is a real number.
The first number is:
6426
It can be rewriten to:
6426/1
So this is: Real, rational, integer, and whole number.
Second number:
√7
This is a real and irrational number (square roots of non-square numbers are irrational numbers).
Third number:
2π
This is a real and irrational number, because π is irrational.
Fourth number:
4.0
This is: Real, rational, whole, and integer.
Fifth number:
√(25/36)
We can simplify that to:
√(25/36) = 5/6
So this is a real and rational number.
Sixth number:
-√16 = -4
That is a: Real, rational, and integer number
Seventh number:
-35
Same as the above one, real, rational, and integer.
Eight number:
-31.8
It can be written as:
-31.8 = -318/10
So this is real and rational number.
