csZachariah Greaves June 11, 2014 MAT 220 40. In an equation, y=kx, when you multiply x by a fixed amount, y is also multiplied by the same amount. If x doubles, then y would also double. As long as x is always as twice as much as y, then they vary directly. 41. The first thing you would do is start with the equation y=kx. Next you would take the given values, plug them in, and solve to find k. Then you would substitute that answer for k into the equation. Finally, you would solve whatever

Espérance mathématique : Définition : de façon générale, l’espérance mathématique correspond à la moyenne des valeurs numériques pondérées avec la probabilité que ce réalise chacune de ces valeurs. Formule : E = p1xr1 + p2xr2 + p3xr3 + … + pnxrn Où p1, p2, p3, … ,pn correspond à la probabilité que les événements 1,2,3,…,n se réalisent Où r1, r2, r3, … ,rn correspond à la valeur numériques des événements 1,2,3,…,n Exemple : Un élève estime qu’il aura une note de 67% pour la compétence

Student Answers and Work Form Unit 5 Version A Student Name: Darryl Gamble 1a Answer: x = (5, 0) 1b. Key work steps: shifted right 5 units X = (5, 0) 1b Answer: x = (100,0) 1b. Key work steps: The vertical asymptote is translated up 2 so will still be the same . So the vertical asymptote of log (x), x = -0 will also be the vertical asymptote of g(x). log(x), x = 0, will also be the vertical asymptote of g(x).An x-intercept by definition is on the x-axis

1) Create and justify a relation that represents a function with the given range. Write your answers as ordered pairs. a) { (0 , 11) , (1 , 20) , (2 , 34) , (3 , 41) } this is because no value is same for the order pairs in x values b)Create and justify a relation that does not represent a function with the given range. Write your answers as ordered pairs. { (0 , 11) , (0 , 20) , (2 , 34) , (3 , 41) } this is the case since the values of X in the first two cases are similar hence making it not
