Which equation matches the graph of the greatest integer function given
bekas [8.4K]

The equation that matches the graph of the greatest integer function is y = [x] - 2

<h3>How to determine the equation?</h3>

The parent function of an step function is represented as:

y = [x]

From the given graph, we can see that the lines are shifted 2 units down.

This means that:

(x,y) = (x,y - 2)

So, we have:

y = [x] - 2

Hence, the equation that matches the graph of the greatest integer function is y = [x] - 2

Alex worked 45.75 hours this week at $7.86 per hour. what is his gross pay? $382.19 $359.60 $314.40 $391.82
Eva8 [605]

Assuming that no overtime was factored into his wages, Alex would have gotten a gross pay of $359.60. This was done by multiplying $7.86 x 45.75 hours.

Assuming that overtime was factored into his wages, Alex would have gotten a gross pay of $382.19. This was done by figuring out how much "time and a half" is for over time. "time" = 7.86; "and a half"= 7.86/2= 3.93

Time AND a half would equal 7.86 + 3.93= 11.79.

So, Alex would get an additional $11.79 for the hours OVER 40 hours which was 5 hours and 75 minutes..

11.79 x 5.75 = 67.79

Total hours for a 40 hour work week for Alex with 7.86 would equal a gross pay of 314.40. Plus 67.79. = 382.19

diego has 90 songs on his playlist. how many songs are there for each genre ? 40% rock , 10% country , 30% hip hop , the rest is
hjlf

Answer:

Diego playlist has 36 songs in rock genre, 9 songs in Country genre, 27 songs in hip hop genre and 24 songs in electronica genre.

Step-by-step explanation:

Given:

Total Songs on playlist = 90

rock = 40%

country = 10%

hip hop = 30%

rest is electronica.

We need to find the number of songs in each genre.

rock = 40%

So Number of songs in rock genre = \frac{40}{100}\times90 = 36\ songs

country = 10%

So Number of songs in country genre = \frac{10}{100}\times90 = 9\ songs

hip hop = 30%

So Number of songs in hip hop genre = \frac{30}{100}\times90 = 27\ songs.

and rest is electronica genre.

Number of songs in electronica genre can be calculated by Subtracting Number of songs in rock genre and Number of songs in country genre and

Number of songs in hip hop genre from Total number of songs.

framing in equation form we get;

Number of songs in electronica genre = 90-30-9-27 = 24\ songs

Hence Diego playlist has 36 songs in rock genre, 9 songs in Country genre, 27 songs in hip hop genre and 24 songs in electronica genre.
