A webmaster makes $24 an hour for the first 38 hours she works during a week and $31 an hour for each hour worked over$38 hours.

Answer:

y=\left\{\begin{matrix}24x & x\leq 38 \\ 31x & x > 38\end{matrix}\right.

Step-by-step explanation:

Here, x represents the number of hours she works in a week and y represents the amount she is paid,

Since, for the hours less than equal to 38,

She is paid $ 24 per hours,

That is, y = 24 x for x ≤ 38,

Also, she is paid $ 31 per hours for the hours more than 38,

That is, y = 31 x for x > 38,

Hence, the piece wish function that shows the given situation is,

y=\left\{\begin{matrix}24x & x\leq 38 \\ 31x & x > 38\end{matrix}\right.

X \leq 38       ->     24x
x > 38        ->      31(x-38) + 912

912 = 24*38   (You will have to have 38 hours to be able to be in this part of the piece wise function)

What does the y-intercept mean? What does the x-intercept mean? Explain what each intercept means and then Identify the x-interc
irinina [24]

x intercept = where the function crosses the x axis (x,0)

y intercept = where the function crosses the y-axis (0,y)

A. y=7/2x-2

x intercept , replace y by 0 and solve for x:

0 =7/2x-2

2= 7/2 x

2 / (7/2) = x

x= 4/7

y-intercept, replace x by 0 and solve for y

y= 7/2x-2

y= 7/2 (0) -2

y=-2

B.

x-intercept:

x=-3

y-intercept

0=-3

It doesn't have a y-intercept.

if a right triangle has one side measuring 3√2 and another side measuring 2√3, what is the length of the hypotenuse?
lina2011 [118]

Answer:

<h2>\sqrt{30}</h2>

Step-by-step explanation:

Given,

Perpendicular ( p ) = 3√2

Base ( b ) = 2√3

Hypotenuse ( h ) = ?

Now, let's find the length of the hypotenuse:

Using Pythagoras theorem:

{h}^{2}  =  {p}^{2}  +  {b}^{2}

plug the values

{h}^{2}  =  {(3 \sqrt{2} )}^{2}  +  {(2 \sqrt{3} )}^{2}

To raise a product to a power, raise each factor to that power

{h}^{2}  = 9 \times 2 + 4 \times 3

Multiply the numbers

{h}^{2}  = 18 + 12

Add the numbers

{h }^{2}  = 30

Take the square root of both sides of the equation

h =  \sqrt{30}

Hope this helps...

Best regards!!

Given: F(x) = x + 2 and G(x) = 3x + 5 (F - G) (x) = <br><br> 1) 4 <br> 2) -3x - 3<br> 3) -2x - 3
mamaluj [8]
This equation is telling you to subtract the value of f(x) from the value of g(x).


f(x)= x + 2
g(x) = 3x + 5

so x + 2 - 3x -5 = -2x-3
