Una química esta estudiando los efectos de los minerales en el crecimiento de las plantas. sabe q el fósforo estimula el crecimiento. decide probar los efectos de diferentes concentraciones de fósforo en las plantas de maiz durante un periodo de 20 dias

1- que hipótesis podría probar la especialista en quimica?
2-cual es la variable independiente y la variable dependiente?
3-enumera las 3 posibles constantes en el experimento.
4-cuales datos cuantitativos podrìa recolectar durante el transcurso del experimento?
5 - cuales datos cualitativos podrìa recolectar durante el transcurso del experimento.
agradezco la ayuda q me puedan dar

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

me! what did you put for this question?

step-by-step explanation:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

won't that be plagrisim thought?
