If h(x) = 5 + x and k(X) =. 1/x which expression is equivalent to (kon)(x)?

Answers

Answer 1
Answer:

Answer:

(5+x)/x

Step-by-step explanation:

Given

h(x)= 5+x

k(x)= 1/x

(koh)(x)=?

Here you multiply

1/x( 5+x)

5/x +x/x

5/x+1 or

5/x +x/x

(5+x)/x

Answer 2
Answer:

For this case we have the following functions:

h (x) = 5 + x\nk (x) = \frac {1} {x}

We must find (k_ {0} h) (x):

By definition of compound functions we have to:

(k_ {0} h) (x) = k (h (x)

So:

k (h (x) = \frac {1} {5 + x}

Finally:

(k_ {0} h) (x) = \frac {1} {5 + x}

Answer:

(k_ {0} h) (x) = \frac {1} {5 + x}

a veterinarian purchases some medication for $19.50 and wants to make a $2 profit. what is the percent markup on this medication

Answers

so he has to sell it at 19.5+2=21.5 dollars

so assume19.5=100%
the markup is 2 dollars
2=x%
find x if 19.5=100%

so since they are proportionite
19.5:100 and 2:x
if we make them fractions and flip one of them then multiply we will get 1 since
2/4=1/2
2/4 times 2/1=4/4=1 so

19.5/100 times x/2=19.5x/200=1
19.5x/200=1
multiply both sides by 200
19.5x=200
divide both sdies by 19.5
x=10.256 aprox
x=10.3% markup

Which of the following functions is graphed below

Answers

Answer:

Option: C is the correct answer.

            C.   y=|x+4|-2

Step-by-step explanation:

We know that the vertex of a absolute value function or a modulus function f(x) of the type:

        f(x)=a|x-h|+k

is denoted by V such that:

          V=(h,k)

By looking at the graph of the function we see that the vertex of the function is:

                        (-4,-2)

A)

               y=|x+4|+2

The vertex of this function is:

              (-4,2)

Hence, option: A is incorrect.

B)

               y=|x-4|+2

The vertex of this function is: (4,-2).

Hence, option: B is incorrect.

D)

                 y=|x-4|-2

The vertex of this modulus function is: (4,-2)

Hence, option: D is incorrect.

C)

                y=|x+4|-2

The vertex of this function is: (-4,-2)

Also, we see that the graph of this function matches the given graph.

           Hence, option: C is correct.

Why is 6 is greater than 5/8 but less than 70

Answers

6 is a whole number and 5/8 is a fraction
Fractions are parts of a whole number
So a fraction is smaller than any whole number
Thats why 6 is greater than 5/8
6 is a number that is in the ones place
Once the ones place is full up the number 9 and is about to go to 10 it goes to the tens place
So anything that is in the tens place is greater than a number in the ones place
6 is in the ones place
70 is in the tens place
Thats why 6 is less than 70
6 is greatwr than5/8 but less than 70 because 5/8 isn't a whole number like 6 and is less than 70 because 7 is more than 5 and since 5/8 isn't a whole number it is less than 70
