Considere a reta r, de equação y = 3x − 1, e as retas u e v, dadas por
u: x + y − 5 = 0
v: 2x − y − 1 = 0
Seja s a reta perpendicular à reta r, que passa pelo ponto de interseção das retas u e v, a equação geral da reta s é:
Considere a função real f definida por
f(x) = 2x
e a função real g definida por
g(x) = f(x + m) + k
em que m, k ∈ R Sendo assim, analise as assertivas abaixo:
I. O gráfico da função g, em relação ao gráfico de f, é deslocado k unidades para cima se k > 0.
II. Se m = 0 e k = 1, então o conjunto imagem de g é dado por Im = { y ∈ R ∣ y > 1 }.
III. A translação horizontal provocada pelo termo m altera o domínio da função exponencial.

( ) In “dogs don’t care” (l. 26), the word “care” could be replaced by “mind” without a significant change of meaning.
( ) The expression “his then-girlfriend” (l. 01) could be understood as the girlfriend he had at that time.
( ) In “The research is mixed” (l. 28), the word “mixed” could be replaced by “conflicting” without significant change of meaning.
( ) In “which dogs can see much clearer than other colours” (l. 23), the word “which” refers to dogs.

I. Os carboidratos miméticos de gordura, como amidos, gomas, hemiceluloses e celuloses, usados como substitutos de gordura, imitam a suavidade e a cremosidade das gorduras nos alimentos, principalmente por retenção de gordura e encorpamento dos sólidos, fornecendo sensação de umectância e textura.
II. As proteínas miméticas de gordura não se comportam como gorduras em temperaturas elevadas, como no caso de frituras. São mais indicadas para substituição em alimentos, especialmente em emulsões de óleo em água.
III. Os substitutos de gordura sintéticos, como a polidextrose e os poliéteres de sacarose, são resistentes à hidrólise enzimática e pouco digeridos no intestino. Muitos substitutos possuem grupos funcionais e estruturais do tipo triacilglicerol, que apresentam grupos éster reversos.
IV. Os trigliceróis sintéticos de calorias reduzidas são obtidos por sínteses variadas, como hidrogenação, esterificação e interesterificação dirigida. Os representantes desse grupo de substitutos são os triglicerídeos de cadeia longa.
