Guys I need major help will give a lot of points if you answer this like a lot of points! Four members of a study team were analyzing the sequence 3, 7, 11, … They found the equation for the sequence to be t(n) = 4n − 1, and they were trying to figure out if 200 could be a term of their sequence.
They made the following statements. Which students justified their statements? Are the justifications convincing? Explain why or why not.
Shinna: “I think it’s not, because all the terms in the sequence are odd and 200 is an even number.”
Aldo: “I think it is, because the equation 200 = 4n – 1 has a solution.”
James: “It can’t be, because the solution to 200 = 4n – 1 is n = 50.25, which is not a whole number. There can’t be a 50.25th term!”
Leslie: “I think 199 and 203 are terms of the sequence, but not 200.”
Now create your own sequence. Then figure out what the 110th term of your sequence would be and whether the number 419 is a term in your sequence. Use multiple representations to justify your answers thoroughly.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
