Answer:

a = 2 m/s²

Step-by-step explanation:

[tex]a = \frac{v-u}{t}[/tex]

where v is the final velocity, u is the initial velocity, and t is the time it takes. the intial velocity is always 0 m/s. given the equation, we subsitute:

Does anyone know how to solve this?

Answers

Answer:

A point in polar coordinates is written as (R, θ)

If we want to transform this point to rectangular coordinates, we get:

x = R*cos(θ)

y = R*sin(θ)

Now we can remember that the sine and cosine functions have a period of 2*pi, then:

cos(θ) = cos(θ + 2*pi)

or:

cos(θ) = cos(θ + 2*pi + 2*pi)

and so on.

Then the point (R, θ) is the same as (R, θ + 2*pi) and (R, θ + k*(2*pi))

where k can be any integer number.

Then if we have a point in polar coordinates:

(-4, -5*π/3)

Then another two polar representations of this point are:

(-4, -5*π/3 + 2*π) = (-4, -5*π/3 + 6*π/3) = (-4, π/3)

Now we can not add 2*π (nor subtract) because we would have an angle outside the range [-2*π, 2*π]

For example, if we have:

(-4, π/3 + 2*π) = (-4, 7*π/3)

And we can not change the value of the radius and get the coordinates for the same point.

So another representation could be something like:

(-8/2, π/3)

Where i just wrote -4 in another way.

Now, a really important point.

When working with polar coordinates, we always use R as a positive number (here you can see that R is negative) so this is not the standard notation for the polar representation of a point.

Answer:

Step-by-step explanation:

2 24/60 = 2 2/5

there are 60 minutes in an hour so you can just put 24 over 60 and the two outside to write it as a mixed number fraction then reduce. If you want to write it as a improper fraction you can multiple 2 times 5= 10 then add 2 to get 12/5

Which of the following could be a possible value for m?
32
33
100

Answers

33 and 100 are correct. Both are greater than 32

The answer is 33 and 100.

Because it says m is larger than 32. It can’t be 32, the sign is only larger than, not larger than or equal to. It also can’t be 31 because it is smaller than 32.

The midpoint of AB is M(-3,-3). If the coordinates of A are (-5, -1), what are
the coordinates of B?

Answers

Answer:

The coordinates of B are (-1, -5).

Step-by-step explanation:

Since the x-coodinate of M is 2 greater than that of B (note that -3 = -5 + 2), the x-coordinate of B is found by adding 2 to -3, obtaining -1. The y-coordinate of M is -3, which is 2 less than the y-coordinate of A; Thus, the y-coordinate of B is 2 less than -3, that is, -5.

The coordinates of B are (-1, -5).

14 Customers into the store over the course of seven minutes how many Internet store after one minute

Answers

Answer:

Step-by-step explanation:

14 divided by 7 is two customers in one minute

Answer:

After one minute there will be 2 people inside the store.

Step-by-step explanation:

First we put this into a proportion. Aka set up like a fraction.

14 (customers) x

------- ---> ------

7 (minute) 1 minute

In order to find x, we must divide by 7 because in order to make the bottom number one on the bottom, you must divide by 7 , so we do the same to the top.

14/7 is 2.

This means that per minute, there are 2 people inside the store.

After one minute, There will be 2 people inside the store.

This game, like many from its era, featured a number of memory corruption bugs, including one which allowed for arbi- trary code execution. That is, there exists some sequence of inputs which, if performed by the player, will allow the player to construct any arbitrary computer program and execute it on the console, subject only to the console's hardware limitations (those limitations being a 16-bit address space). Suppose we were to create an emulator that lifted those restrictions. It would support a superset of the Game Boy's instruction set with a variable length instruction capable of reaching any memory address within its own hardware's infinite memory. We will call this emulator E, and run it on a Turing machine (with all of its infinite tape). E will receive as input on its tape in the form of every button press from the player, for every frame, until they power off the game. It will also write to the tape as output, every frame that should appear on the screen. Can we construct a Turing machine that will decide whether a game of Pokemon Yellow, when run within the emulator E, will ever display the ending credits?
