What is a graph?

A graph, which is a diagrammatic depiction of a network, describes the connection between lines and points. A graph consists of various points and the separation between two of them.

It doesn't matter how much time the lines are or where the points are located. A node is a name for each constituent in a graph.

For example to draw the equation y = 6x +9 this will draw a straight line in the coordinate geometry.

The solution of any equation is a point of intersection of a graph as we can see that the graph which is present in the question has only one intersection so there will be only one answer.

A soccer ball is kicked toward the goal. The height of the ball is modeled by the function h(t) = −16t2 + 48t, where t equals the time in seconds and h(t) represents the height of the ball at time t seconds. What is the axis of symmetry, and what does it represent?

t = 3; It takes the ball 3 seconds to reach the maximum height and 3 seconds to fall back to the ground.
t = 3; It takes the ball 3 seconds to reach the maximum height and 6 seconds to fall back to the ground.
t = 1.5; It takes the ball 1.5 seconds to reach the maximum height and 3 seconds to fall back to the ground.
t = 1.5; It takes the ball 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.

Answers

Answer:

isabel saves the most of their salary each month

Step-by-step explanation:

Let us assume the Salary of Gavin, Harry & Isabel be $100

Since

Gavin saves 28%

So his saving amount is Gavin

= 28% of $100

= $28

As harry spends 3 ÷ 4 of his salary

So Harry Spenings is

= (3  ÷ 4) of $100

= $75

Now

Harry Saving is

= $100 - $75  

= $25

Also the ratio between isabel saves, and spend is 3:7

3k + 7k = 10k = 100S

 k = $10

Now

the amount of salary isabel saves

= 3k

= 3 × $10

= $30

Now

$30 > $28 > $25

i.e.

isabel Saving >  Gavin Savings > Harry Savings

Hence, isabel saves the most of their salary each month

Estimate the probability that on the next roll the score will be 4.
b)
If the dice is rolled 400 times, about how many 2s would you expect to get?​

Answers

Answer:

a) 1/10

b) 110

Step-by-step explanation:

A) we start by getting the total number of rolls

That would be;

11 + 22 + 7 + 8 + 13 + 19 = 80

The frequency of getting a 4 is 8

The probability that the next roll will be a 4 is;

8/80 = 1/10

b) Firstly, we get the probability of getting a 2

We have this as:

22/80

So for 400 rolls, the number of 2’s will be;

22/80 * 400

= 22 * 5 = 110

Ajar contains $36.25 in dimes (10 cents) and quarters (25 cents). There are 250
coins in the jar. How many quarters are there in the jar?

Answers

Answer:

Step-by-step explanation:

The jar contains 2 types of coins dimes and quarters

the total amount is equal to 36.25 dollars

the total number of coins is 250

let  number of dimes be x and quarters be y

let us put the equation

0.10x + 0.25y = 36.25

for our convinience convert all money to cents i.e. = 3625 cents

now the equations are

10x + 25y = 3625

x     +    y   = 250

we need to solve for y i.e. number of quaters

y = 250 - x

rewrite the equation substituting y in x place

10(250 - y) +25 y = 3625

2500 - 10y +25y = 3625

15y = 1125

y = 75

so the number of quarters = 75

cross checking :

number of dimes = 250 - 75 = 175

total = 10x175 + 25x75 = 1750 + 1875 = 3625 = $36.25

Step-by-step explanation:

have a nice day!! ^_^

The coordinate of A` is (5,5) , the coordinate of B` is (5,1), the coordinate of C` is (2,1) and the coordinate D` is (1,5).

What is the coordinate of a point?

A pair of number that describes the exact position of a point on  a cartesian plane by using the horizontal and vertical lines is called the coordinate of a point. Coordinates are usually denoted by (x, y).

From the figure we can see that A` is 5 unites right of vertical line and 5 unit upward the horizontal line. So, the coordinate of A` is (5,5).

Similarly, B` is 5 unit right of vertical line and 1 unit upward the horizontal line. So, the coordinate of B` is (5,1).

C` is 2 unit right of vertical line and 1 unit upward the horizontal line. So, the coordinate of C` is (2,1).

And, D` is 1 unit right of vertical line and 5 unit upward of horizontal line. So, the coordinate of D` is (1,5).

Hence the coordinates of A`B`C`D` is (5,5), (5,1), (2,1) and (1,5) respectively.

Answers

Answer:

81 / 64

Step-by-step explanation:

The ratio of the areas can be obtained thus :

Area of ∆ABC / Area of ∆PQR

Area of ∆ABC / Area of ∆PQR = AB² / PQ²

AB = 1.8 ; PQ = 1.6

AB² / PQ² = 1.8² / 1.6²

Given:

The area of a rectangle = 14 square units.

The side lengths are a and b.

[tex]a=2\dfrac{1}{3}[/tex]

To find:

The value of b.

Solution:

We know that, the area of a rectangle is:

[tex]Area=Length\times Width[/tex]

The area of the given rectangle is:

[tex]14=a\times b[/tex]

[tex]14=2\dfrac{1}{3}\times b[/tex]

[tex]14=\dfrac{2(3)+1}{3}b[/tex]

[tex]14=\dfrac{6+1}{3}b[/tex]

On further simplification, we get

[tex]14=\dfrac{7}{3}b[/tex]

[tex]14\times 3=7b[/tex]

[tex]42=7b[/tex]

Divide both sides by 7.

[tex]\dfrac{42}{7}=b[/tex]

Answers

Given:

Point on straight line = (-6,4)

Gradient = -2

To find:

The equation of the line.

Solution:

Point-slope form: If a line passes through the point [tex](x_1,y_1)[/tex] with slope m, then the equation of the line is

[tex]y-y_1=m(x-x_1)[/tex]

The line passes through the point (-6,4) with slope -2. So, the equation of the line is:

[tex]y-4=-2(x-(-6))[/tex]

[tex]y-4=-2x-12[/tex]

Adding 4 on both sides, we get

Do you wonder what your kid is playing all the time and is it affecting them? Kids/teens are playing a video game called Fortnite and parents and teachers are debating if this game is an addiction or just an amusement. Parents, teachers, and scientists are trying to figure out the outcome of this issue if it is addicting. Some people think that this game is just an amusement and something for kids to enjoy but others think it is an addiction and that it is affecting them. Although Fortnite is an amusing game that kids can have fun with, we need to understand that kids play it too much because they can be affected in school and themselves because of not finishing their work, and it is also affecting their mental health, and it is a big distraction with life at home as well. First, why Fortnite is an addiction is because kids will not be able to get their work done in class. In the article "Fortnite-Addiction or Amusement" it states Teachers are finding that this is the hottest topic of conversion, and they are spending all their time at home playing this game, forgetting about their academic responsibilities" (Crouch 13). This explains that kids are talking about Fortnite instead of doing their school work. One time when I was at school we were doing a school project and I got assigned with classmates that liked to play Fortnite and that is all they talked about during the time we had to do the project and I did pretty much all the work. In conclusion, kids are spending way too much time talking about it instead of working at school. I Next, why Fortnite is an addiction is because it could be affecting their own health. According to the author of the article "Fortnite-Addiction or Amusement" it states "According to Psychology Today, "[too much screen time] can unintentionally cause permanent damage to their still-developing brains" (Crouch 10). This explains that playing video games can cause permanent damage to their brains. To explain further this means when looking at a screen for too long this may cause their permanent damage to their brains because they are still growing. In conclusion, too much screen time can cause permanent damage to the brain unless already fully developed. On the other hand, Fortnite can be an amusing game by it being free for everyone. According to the text it states "First, one of the top reasons why Fortnite is so popular is because the initial game is free" (Crouch 5). However, that means that the game is more accessible and becomes more of a distraction with more kids/ieens. According to the author Though many will argue that Fortnite is not the root of the problem in households and classrooms, many parents and teachers disagree, and they are seeing this game become a huge distraction and addiction in and out of the classroom" (Crouch 9). We need to find a way to stop this being such a distraction. In conclusion, although Fortnite is an amusing game that kids can play with friends and after school, we need to understand that kids need to stop making it such a distraction because of not finishing their work, and it is also affecting their mental health, and it desensitizes kids. Teachers in school are noticing that kids in school are only talking about the game Fortnite and it's distracting them from doing work. Also since kids are playing the game way too much it could affect their health and it mostly affects their brian permanently because their brian is not fully developed. Fortnite can be good because it's free but it causes too much distraction and kids will not get work done in school. Fortnite can be fun but too much can be bad. PLEASE HELP MEEEEE!!!!!
