Best ResponseYou've already chosen the best response.3we know that your function has to be a polynomial of degree 2 from your drawing we see that x=6 and x=6 are two zeroes of the requested polynomial

Best ResponseYou've already chosen the best response.0Oh! So would it be 1(x+6)(x6) ??

Michele_Laino

Best ResponseYou've already chosen the best response.3the simpler polynomial which satisfies those requisites is: \[y = \left( {x  6} \right)\left( {x + 6} \right)\] even if, we have to check if my function contains the point (0,36) does my function pass at point (0,36)?

Best ResponseYou've already chosen the best response.3you have to create a table for a straight line like this one: dw:1438706644480:dw

Best ResponseYou've already chosen the best response.3step#1 please chose two point on your rainbow

Best ResponseYou've already chosen the best response.3you have to choose 2 values for xcoordinate

Best ResponseYou've already chosen the best response.3between 6 and 6

Michele_Laino

Best ResponseYou've already chosen the best response.3no, your value has to be less than 6 and grater than 6

Best ResponseYou've already chosen the best response.3x=5 is right! the other value can be x=2

Michele_Laino

Best ResponseYou've already chosen the best response.3what do you think?

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3now we have to compute the corresponding yvalue, so, if x=5 then: y=5^2+36=25+36=11

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3whereas if x=1, then: y=1^2+25=...?

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3sorry if x=1, then: y=1^2+36=35 we have these points: (1,35) and (5,11)

Best ResponseYou've already chosen the best response.0so then we would have to make a chart, and another function right?

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3now: step#2 we have to write the equation of the straight line which passes at points (1,35) and (5,11)

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3for example we can use this equation: \[\Large y  35 = m\left( {x  1} \right)\] where: \[\Large m = \frac{{{y_2}  {y_1}}}{{{x_2}  {x_1}}} = \frac{{11  35}}{{5  1}} = ...?\]

Michele_Laino

Best ResponseYou've already chosen the best response.3so, what is the equation of your straight line?

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3we have to substitute our value of m, into my equation above: \[\Large y  35 =  6 \cdot \left( {x  1} \right)\]

Best ResponseYou've already chosen the best response.3please, simplify

Best ResponseYou've already chosen the best response.3I got: Y=6x+41 am I right?

Michele_Laino

Best ResponseYou've already chosen the best response.3ok! Now the exercise asks you at least four points

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3you have already two points: (1,35) and (5,11)

Michele_Laino

Best ResponseYou've already chosen the best response.3so you have to choose another 2 values for x, and compute the corresponding value for y. Please keep in mind that x has to be greater than 6 and less than 6

Michele_Laino

Best ResponseYou've already chosen the best response.3whit those four points you have to create a table like this: dw:1438708104245:dw

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3ok! x=2 is good, so: y= 2^2+36=4+36=...?

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3so the third point is: (2,32)

Michele_Laino

Best ResponseYou've already chosen the best response.3now, we can choose x=3

Michele_Laino

Best ResponseYou've already chosen the best response.3I got this: y=(3^2)+36=9+36=27

Best ResponseYou've already chosen the best response.0Yayyy! We did it! So just to make sure, the 2nd equation is y=6x?

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3so, the requested table is: dw:1438708531419:dw

Michele_Laino

Best ResponseYou've already chosen the best response.3the second equation is: \[\Large y =  6x + 41\]

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0oh, so is it possible that we could have plug the points into that equation to get the points too?

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3I have made an error, at x=2 we have to compute the value of the ycoordinate of the line, namely: \[\Large y =  6 \cdot 2 + 41 = ...\]

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3similarly at x=3: \[\Large y =  6 \cdot 3 + 41 = ...\]

anonymous

Best ResponseYou've already chosen the best response.0so can we draw the chart again and see?

Michele_Laino

Best ResponseYou've already chosen the best response.3ok! so we got these points: (2,29) and (3,23)

Best ResponseYou've already chosen the best response.0what would the domain/range be?

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3the domain of the direction of the drone, it is all the real line

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0so would the domain be 6 and 6 then?

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3it is the domain of the rainbow, I think

anonymous

Best ResponseYou've already chosen the best response.0Thanks for all your help!!!!! :D

Michele_Laino

Best ResponseYou've already chosen the best response.3please wait, I have made another error, the fourth point is: (3,59)

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Good thing you caught that!

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3since we have: \[\Large y = \left( {  6} \right) \cdot \left( {  3} \right) + 41 = 18 + 41 = 59\]

Michele_Laino

Best ResponseYou've already chosen the best response.3the domain of the rainbow is the subsequent interval: (6,6) whereas its range is (0,36)

anonymous

Best ResponseYou've already chosen the best response.0what would that represent?

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3the range is the set af possible values of the function x^2+36 when x is inside the domain

Best ResponseYou've already chosen the best response.0Is the linear function you created positive or negative? Explain.

Michele_Laino

Best ResponseYou've already chosen the best response.3I think that it represents the possible Rainbow heights with respect to the Earth's surface

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.3the linear function which we have created has a negative slope, so I think it is negative

anonymous

Best ResponseYou've already chosen the best response.0What are the solutions or solution to the system of equations created? Explain what it or they represent.

Michele_Laino

Best ResponseYou've already chosen the best response.3the requested solution is given by the coordinates of the intersection points, namely: (1,35) and (5,11)
