What is the domain of <br> F(x)=√x ?<br><br> (PLEASE HELP ASAP)
leva [86]

Option C. all real numbers greater than 0 is the correct answer

Further explanation:

Domain is the set of all inputs on which the function is defined or real.

The given function is:

f(x)=\sqrt{x}

As the function involves a square root, we have to avoid negative numbers.

  • All positive real numbers will produce defined output so the positive real numbers will be included in the domain.
  • If we look at negative real numbers, we will be taking square root of a negative number which will not result in a real number

So the domain will only include positive real numbers.

Hence, Option C. all real numbers greater than 0 is the correct answer.

Keywords: Domain, Domain of radical functions

The base of a triangle measures (3x − 6) units and the height measures (2x + 4) units. Part A: What is the expression that repre
Anettt [7]

To answer this item, we use the equation given for the calculation of the area of the triangle.

                                A = 0.5bh

Substituting the known expressions,

                      A = (0.5)(3x – 6)(2x + 4)

 

Part A: Use distribution method to simplify the expression for the calculation of area.

 

                         A = 0.5(6x^2 + 12x – 12x – 24)

                           A = 0.5(6x^2 – 24)

<span>                          A = 3x^2 – 12</span>

 Part B: The equation for area of has a degree of two because the highest exponent is 2.

<span>Part C: The closure property of polynomials is always closed for multiplication.</span>

You are designing a 1000 cm^3 right circular cylindrical can whose manufacture will take waste into account. There is no waste i
asambeis [7]

Answer:

 h /r  =  2.55

Step-by-step explanation:

Area of a can:

 Total area of the can = area of (top + bottom)  + lateral area

lateral area  2πrh    without waste

area of base (considering that you use 2r square)  is 4r²

area of bottom      ( for same reason )                           4r²

Then Total area  =  8r² + 2πrh

Now can volume is   1000 = πr²h        h = 1000/πr²

And  A(r)  =   8r² + 2πr(1000)/πr²

A(r)  =   8r² + 2000/r

Taking derivatives both sides

A´(r)   =  16 r    - 2000/r²

If A´(r)  =  0              16 r    - 2000/r²   = 0

(16r³  - 2000)/ r²  =  0        16r³  - 2000  =  0

r³  =  125      

r = 5 cm      and      h  = ( 1000)/ πr²      h  = 1000/ 3.14* 25

h = 12,74  cm

ratio   h /r  =  12.74/5         h /r  =  2.55
