The value  -16.5 tells us the displacement between his current position and his initial position.

Displacement is defined as the minimum distance between two points. It is a vector quantity and needs direction with magnitude.

It is given that

Initial position =14.2 m

Final position=-2.3 m

14.2+(16.5)=-2.3

To understand this, we need to first calculate the displacement between his initial and final position

Displacement = Final pposition - Initial position

Displacement= -2.3-14.2

Displacement =-16.5 m

So: -16.5m is the total displacement from the start position (i.e. off the cliff) and current position (beneath the water surface)

I got it right on khan. Btw I don't know if someone said this already bc I am sooo tired bc it's 1 am :(

You're supposed to post all the photos in a single question.  Anyway, this is the one that has a domain and range of all real values.

We can see a domain of all real values -- there's no x that's not included.

We can see the range of all real values -- there's no y that's not included.

Step-by-step explanation:

First we have to figure out which order to solve this equation.

Following the rules of PEMDAS, we know it would be 5 - [6 x 8 ( ÷ 8 ) ] + 3.

Please tell me if you need a larger explanation on PEMDAS, or what the brackets and parenthesis mean.

Next we simplify the equation, bringing us to the answer, 2.

Once again, please tell me if you need to know how I simplified the equation.

Hope this helped :)

Answer:

The following graph represents the function g(x)=|x+4| +2

1) On a coordinate plane, an absolute value graph has a vertex at (-4,2)

Step-by-step explanation:

A vertex can bed defined as a point where two lines meet. In a graph, a vertex can also be interpreted as the point where the direction of the line or curve change

The function is given by:

[tex]g(x)=|x+4|+2[/tex]

which is an absolute value function. We need to find the vertex of the graph.

The graph drawn is attached below.

We can see in the graph that at x = -4 and y = 2 , a point is formed where the straight line changes its direction.

So the vertex is formed at (-4,2)

Answer:

A. (-4,2)

Answer:

0.25 seconds

Step-by-step explanation:

First let's expand the function h:

[tex]h = -16(t- 1/4)^2 + 49[/tex]

[tex]h = -16(t^2 - t/2 + 1/16) + 49[/tex]

[tex]h = -16t^2 + 8t - 1 + 49[/tex]

[tex]h = -16t^2 + 8t + 48[/tex]

To find when the marshmallow reaches the maximum height, we can use the formula to find the vertex of the quadratic function, and the x-coordinate of the vertex is when we have the maximum height:

[tex]x_{vertex} = -b/2a[/tex]

In our equation, b = 8 and a = -16, so:

[tex]t_{vertex} = -8 / (-32) = 0.25\ seconds[/tex]

Answer:

Associate the numbers or coordinates with something in your life. Think of it from every possible aspect. For example, number 7. I just think of it as "7 is half of 14, there are 7 days in a week, 7 can be said as 70, which means 7 tea cups. See like that, now when you try and remember the numbers, you are able to pick up on these trail of thoughts are trace it back to its origin, which here is 7.

Answer:

Multiplying the vertex matrix with the matrix gives us a reflection matrix. The most common matrix reflections are seen as a reflection in the x-axis as well as reflection in the y-axis. It can also be reflected by  90 degrees or by 180 degrees. So, one way to remember the elements is by multiplying the given matrix by a unit matrix. And on the other hand, you can remember the elements remembering by what degree we are reflecting the matrix. This way makes it easier to remember the elements.

Answer: 30 dominoes in total.

Step-by-step explanation:

Each line is 21 inches long.

the space between dominoes is 1 + 1/2 inches.

(assuming that the distance includes the domino itself) Now, we need at least two dominoes to see this distance,

The we have N + 1 dominoes per line, and the distance is:

N*(1 + 1/2)inches = 21 inches

If we find N, we can find the number of domineoes in each line:

N = 21/(1 + 1/2) = 14

This means that we have 14  + 1 = 15 dominoes in each line, and we have two lines, so we have 30 dominoes in total.

Answer:

42

Step-by-step explanation:

During the season, 40% of the goals are scored the by the star player.  This means that 60% of the goals are scored by everyone else.

100% - 40% = 60%

To find how many goals are scored by the rest of the team, convert the percentage to a decimal.  You then have to multiply the decimal by the total goals scored.

60% = 0.6

70 × 0.6 = 42

The rest of the team scored 42 goals.  

Answer:

42

Step-by-step explanation:

40% of 70=28

Answer:

x = 10

Step-by-step explanation:

Since B is the midpoint of segment AC, then AB = BC.

AB = BC

3x - 8 = x + 12

2x - 8 = 12

2x = 20

x = 10

As per the given information, the value of x is 10. For understanding, check the calculations provided below.

A midpoint is a point that divides a line into two parts equally.

In the given diagram,

B is the midpoint of line segment AC. Midpoint B divides the line segment AC equally.

When a midpoint B divides equally then AB = BC

Given that,

AB = 3x-8 and BC = x+12

B is the midpoint of line segment AC.

So,

AB = BC

Substitute the expression and solve for x

AB = BC

3x-8=x+12

Subtract x,

⇒ 3x-x-8 = x-x+12

⇒ 2x-8=12

Add 8

⇒ 2x = 12+8

⇒ 2x = 20

divide by 2

∵ x = 10

Thus, the value of x is 10.

Answer:

x=-3

Step-by-step explanation:

2^4x = 8^x-3

writing 8 as 2^3

2^4x = 2^3^x-3

We know a^b^c = a^(b*c)

2^4x = 2^(2*(x-3))

2^4x = 2^(2x-6)

The bases are the same so the exponents are the same

4x = 2x-6

Subtract 2x from each side

4x-2x= 2x-6-2x

2x=- 6

Divide by 2

2x/2 = -6/2

x = -3

Answer: £18

Step-by-step explanation:

let Bridget get £x,

Stephen gets 3x, Richard gets 2(3x)

Equation is x + 3x + 6x = 60

10x = 60: x = 60/40 = 6

Bridget gets £6

Stephen gets 3x = 3 x 6 = £18

Richard gets 2(3x) = 2 x 18 = £36
