Answer 1

Answer:

c. (x +3)(x + 1)

Step-by-step explanation:

Factoring an equation is a way of expressing an equation as the product of other linear expressions. The following expression,

[tex]x^2 +4x +3[/tex]

Can be represented as the product of the following,

[tex](x+3)(x+1)[/tex]

To check this, one can distribute, one of the expressions over the other, then simplify, the result should be the starting expression,

[tex](x+3)(x+1)\\[/tex]

Distribute,

[tex](x)(x)+(1)(x)+(3)(x)+(3)(1)[/tex]

Simplify,

[tex]x^2 +x +3x + 3\\[/tex]

[tex]x^2 +4x +3[/tex]

1. 18.85in

4. 25.13m

Step-by-step explanation:

I got you

So to find the circumference of any circle we use the equation 2pi(r)

2(3.1415)(3)= 18.85in for the first one because radius is half of the diameter which is 6 so half of 6 is 3

For 4. 4m is actually the radius so just plug that into the equation 2pi(4)=25.13m

Answers

Answer: the movie was 1 hour and 35 minutes and Amar got home at 6:15 P.M.

Step-by-step explanation:

to find out how long the movie was you have to find the distance between the time frames 3:55 and 5:30.

3:55+1 hour= 4:55

4:55+5 minutes= 5:00

5:00+30 minutes= 5:30

Add the times to find how long the movie was.

This is how I found how long the movie was.

To find out when Amar got home you have to do the same thing as well.

5:30+30 minutes= 6:00

6:00+15 minutes= 6:15

Hope this helps!

A single-server waiting line system has an arrival pattern characterized by a Poisson distribution with 3 customers per hour. The average service time is 12 minutes. The service times are distributed according to the negative exponential distribution. The average time a customer can expect to wait in line is:

Answers

Answer:

18 minutes

Step-by-step explanation:

Given that:

The arrival time = 3 customers / hour

The avg. service rate (s) = 12 minutes per customer

To hour, we have:

[tex]s = \dfrac{60}{12}[/tex]

s = 5 customers/ hour

Thus, the required average time for a customer needs to wait in line is:

[tex]= \dfrac{3}{5}\times (5-3) hours \\ \\ = \dfrac{3}{5}\times 2 \\ \\ = \dfrac{3}{10} \ hours[/tex]

To minutes;

[tex]= 3 \times \dfrac{60}{10} \ minutes[/tex]

= 18 minutes

It was a dark quiet night, Halloween night when Celestia screamed. Celestia was a dragon human hybrid with dark blue hair and kind light blue eyes, dark blue wings, a dark blue tail, her hair was always in what looked like two buns on top of her head the little bit of hair that was too short-covering her ears with her bangs shadowing her face, she was in a witch costume that was black dark purple and dark pink with a black hat. Nikki came running her longish white and purple hair in a messy bun, she was wearing her mad scientist costume but the fake blood looked suspiciously realistic. Wannabe ran in looking like the human form of sans along with Angel a few feet behind him dressed as a fairy. Nikki stood staring trying not to cry. Nikkis friend Emery came in wearing her police uniform on and blue blonde hair up in a ponytail along with Rihanna in her outfit that she wore at her concert the night before, the light baby blue costume made her light pink eyes stand out and her fox tail nearly invisible under a big black bow, her hair in ponytails right behind her fox ears. The two stared in horror at what seemed to have happened, one of their friends had been brutally murdered but their face was unrecognizable from the damage. Nikki stood up and took ad headcount matching names with faces until she realized who it was. Im going to find the person who did this and make them pay, Nikki said in a dark evil angry voice, she was mad and near her breaking point. Nikki left the room unable to look at her friend lying there dead while everyone else looked at each other. Kind convenient YOU found him like this Celie Rihanna said to Celestia glaring at her, the two never liked each other and were always fighting. First of all, I couldnt handle the blood. Second of all, thats my friend! Why would I hurt him!?!? Celestia snapped, angry she was accused of the crime. You found him like this. That's a little suspicious dont you think? Rihanna said giving Celestia looks. I hate to say this but Nikki could have been faking the blood on her costume looks a bit too realistic Angel said her voice trailing off, she hated to accuse Nikki but at this point, they were all suspects except for Angel. She had said before that she'd never been able to kill someone and get away with it shed end up admitting she did it. Nikki came back in a completely different costume, her Sara Sanderson costume to be exact. Why did you change costumes? Angel questioned Nikki, changing costumes because there was what looked like blood on the other was suspicious. You act like I can choose to wear only one costume, heck Ill probably end up wearing a cosplay before we figure out who did this, Nikki answered, it was true Nikki tended to wear up to ten outfits a day so why would today be any different? Emery glared at Nikki, she didnt believe her story. Seems pretty convenient she had to change costumes so soon... She thought suspecting Nikki was hiding something. Lets do this Danganronpa style! Angel shouted, she had always thought how they did the class trials on that anime and in the game was cool. Everyone got to a podium and glared at one another. I was passing out candy to the trick-or-treaters, Rihanna said then turning her head to Celestia who was on her left. I was in the Bathroom, Celestia said, nobody was going to question her now. I was fixing my fursuit, one of the ears fell off, Nikki said with the tail to her fursuit in hand. I was outside sitting on the porch, Emery said pointing at the door.
