  1. Aim: Review for Test #4 TEST TOPICS : • Law of Cos • Vector Problems • Bernoulli’s Probability • Daily Do Now Questions such as • Abs value inequalities • Operations with radicals. • Logarithmic expression TEST WILL BE TUESDAY, MAY 25

  2. Aim: Review for Test #4 Do we need to know any formulas for the test ? 3) nCr • pr • (1 – p)n – r

  3. Aim: Review for Test # 4 Do Now: 1) In triangle ABC, a = 6, b = 12, and m < C = 60. What is the length of side c to the nearest integer? 2) In triangle ABC, a = 6, b = 7, and c = 8. What is cos A in simplest fraction form?

  4. Aim: Review for Test #4 The accompanying diagram shows a resultant force vector, R. Which diagram best represents the pair of component force vectors, A and B, that combined to produce the resultant force vector R?

  5. Aim: Review for Test #4 3) Forces of 40 pounds and 70 pounds act on a body at an angle measure 60º. Find the magnitude of the resultant of these forces to the nearest hundredth of a pound. 4) The sides of a triangle have lengths 58, 92, and 124. Find, to the nearest tenth degree, the largest angle of the triangle.Find, to the nearest integer, the area of the triangle. 5) Two forces of 14 and 30 act on a body forming an obtuse angle with each other. If the resultant force has a magnitude of 20, find the angle between the two forces to the nearest degree.

  6. Aim: Review on Test #4 As shown in the accompanying diagram, a circular target with a radius of 9 inches has a bull’s-eye that has a radius of 3 inches. If five arrows randomly hit the target, what is the probability that at least four hit the bull’s-eye?
