Answer:

(f+g)(x)=(2^{x} +x-3)^{\frac{1}{2} }

Step-by-step explanation:

I assume you are asking about the question on edmuntum that wants (f+g)(x)?

in that case 2^{\frac{x}{2} } can be rewritten as (2^{x})^{\frac{1}{2} } and \sqrt{x-3} can be rewritten as (x-3)^{\frac{1}{2} }.

Now all that needs to be done is grouping all the terms in the same parentheses and adding in an addition sign to get (2^{x} +x-3)^{\frac{1}{2} }.

<h2>Explanation:</h2>

I don't know what your question, but I'll assume you want the composition of two functions.

Remember that:

The \ \mathbf{composition} \ of \ the \ function \ f \ with \ the \ function \ g \ is:\\ \\ (f \circ g)(x)=f(g(x)) \\ \\ The \ domain \ of \ (f \circ g) \ is \ the \ set \ of \ all \ x \ in \ the \ domain \ of \ g \\ such \ that \ g(x) \ is \ in \ the \ domain \ of \

f(x)=2^\frac{x}{2}} \\ \\ g(x)=\sqrt{x-3}

Suppose in this case you want (g \circ f)=g(f(x)), then:

g(f(x))=\sqrt{2^\frac{x}{2}-3}

Describe two methods for converting a mixed number to a decimal
uysha [10]
R example: 6 1/2 = 13/2 = 6.5

For the first example, six and a half is equal to thirteen halves, which is then equal to six point five. To do this, the rule to turn a mix number into a fraction is by multiplying the 2 with the 6 and then add the answer to 1, which gives 13/2 (Remember to always give the same denominator). Finally, thirteenth halves is equal to six point five (because when you divide 13 by 2, you get 6 and one left over. To continue dividing, add a 0 , and so 10 goes into 2 is five. so the decimal is 6.5

<h3><u>Answer</u> :- </h3>

c) 0.01

<h3><u>Solution</u> :-</h3>

To Write percentage in decimal or fraction we divide it by 100

therefore,

\begin{gathered}\\\implies\quad \sf 2\% = \frac{2}{100} \\\end{gathered}

\begin{gathered}\\\implies\quad \sf 2\% = 0.02 \\\end{gathered}

Half of 0.02 = \sf\frac{1}{\cancel2} \times\cancel{0.02}

\implies\boxed {0.01}

Translate the following into an algebraic expression: A number is 30% of 20% of the number x.
bezimeni [28]

Answer: 0.06x

Step-by-step explanation:

  • An algebraic expression is an expression consist of integer constants, variables, and algebraic operations.

The given statement:  A number is 30% of 20% of the number x.

The required algebraic expression would be:

30% of 20% of x

=\dfrac{30}{100}\times \dfrac{20}{100}\times x  [we divide a percentage by 100 to convert it into decimal]

=\dfrac{6}{100}\times x\\\\=0.06x

Hence, the required algebraic expression would be :

0.06x
