The function h(x) is a transformation of the square root parent function,
kondaur [170]

Answer:

A. h(x)=\sqrt{x-3}

Step-by-step explanation:

<h3>Step 1: Definition</h3>

The parent function of \sqrt{x} is translated to the left when h is positive in the transformation \sqrt{x+h}.

If h is negative, the graph translates towards the left with the distance equal to the value of h.

<h3>Step 2: Implementation</h3>

Here the graph moved 3 units towards the right. This means that h is negative and has the value of 3.

So, plugging that into the parent function for translation, the function becomes:

h(x)=\sqrt{x-3}

Charles will babysit for up to 4 hours and charges $7 per hour. Write a function in function notation for this situation.
I am Lyosha [343]
Assume Charles charges $7*3=$21 if he babysits for 2,5 hours (that is 2 and a half hours).

That is we are not considering Charles babysitting exactly 1, 2, 3 or 4 hours, but also in between times.


then we can write the following piecewise function to describe the situation:


f is a function from (0, 4] to {$7, $14, $21, $28}

f(x)=\begin{cases} &#10;      \$7 & if \enspace \enspace x\leq 1 \\&#10;      \$14 & if \enspace \enspace 1\ \textless \  x\leq 2 \\&#10;      \$21 & if \enspace\enspace 2\ \textless \ x\leq 3 \\&#10;      \$28 & if \enspace\enspace 3\ \textless \ x\leq 4 \&#10;   \end{cases}

Can someone pleaseee help!!!
krok68 [10]

Answer:

Step-by-step explanation:

use known angles and rules to find unknown values

vertical angles (pairs of angles on opposite sides of an intersection) are equivalent

supplementary angles (angles found next to each other on a line) add up to 180 degrees

opposite interior angles are equivalent

And I don't remember the name of this kind of angle, but angle 1 and 10 are equivalent because they are found on the same "location"

using these rules you can find all missing angles.

1= 75

2=180-75=105

let me know if you need more help than this
