ANSWER: 8-4 Trigonometry Express each ratio as a fraction and as a decimal to the nearest hundredth. 1. sin A 3. cos A SOLUTION: The cosine of an angle is defined as the ratio of the adjacent side to the hypotenuse. So‚ ANSWER: SOLUTION: The sine of an angle is defined as the ratio of the opposite side to the hypotenuse. So‚ 4. tan A ANSWER: 2. tan C SOLUTION: The tangent of an angle is defined as the ratio of the opposite side to the adjacent side. So‚ ANSWER: 3. cos A SOLUTION:

Team Exercise 4 Why has Altius lost market share? 10 points i) There was a decline in the economy‚ which led to less people spending money on golf. Now even during a modest recovery the industry is not nearly back to the glory of its past‚ and many golfers who stopped golfing are not returning‚ and few people are picking up the game for the first time. The declining interest created a major decline in spending. ii) Altius marketed itself exclusively as a premium brand. While other

Q1: Summarise the main development of a child age 0-2‚ 2-5 & 5-8 yrs. 0-2 Years As a child grows the changes in weight and height size are measured on a centile chart‚ these charts show the expected pattern at the particular ages. Development refers to the skills and abilities that you learn through life‚ but as we all know children are all individual and so when centile charts are used they are based on the “average” child but all children meet these different goals in their own time and don’t

open them anymore or reopen them before depolarization. This is due to the refractory period. 3) Why is it only possible to induce an extrasystole during relaxation? Because cardiac muscle is able to depolarize after repolarization takes place. 4) Explain why wave summation and tetanus are not possible in cardiac muscle tissue. How well did the results compare to your prediction? Cells do not show tetanus or summation because cardiac cells have both long action potentials and long twitches. Activity
