Em um rally de regularidade, os participantes, que competem em duplas, devem realizar cada trajeto rigorosamente no tempo determinado pela organizaç? o. o tempo de cada equipe é comparado com o tempo ideal. para cada décimo de segundo atrasado, perde-se 1 ponto, e para cada décimo de segundo adiantado, perdem-se 2 pontos. o resultado é revelado após o término da prova e vence a dupla que perder menos pontos. observe os tempos realizados por 3 equipes: lucas e daniel 2 min 36 s, mari e laura 1 min 59 s, rafael e jean 2 min 43 s

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
