CCII Unit 5 Warm-Ups

Warm-Ups (Monday 11/17) a) Describe the transformation from the parent graph b) Domain:c) Range: d) Vertex:e) Axis of Symmetry:

Warm-Ups (Tuesday 11/18) 1.sin (62 o ) 2.cos (132 o ) 3. tan (-87 o ) 4.4tan (x) = cos (x) – 4 = sin (x) + 5 = 2.57

Warm Ups (Wednesday 11/19) Sketch the following graph (and table of x and y values) : y = 2sinx +1 a)Amplitude: b)Midline: c)Increasing: d) Decreasing:

Warm-Ups (Thursday 11/20) A ladder leans against a second- story window of a house. If the ladder is 25 meters long, and the base of the ladder is 7 meters from the house, how high is the window? (Hint: Draw a Triangle, label it, then use the Pythagorean Theorem!)

Warm-Ups (Monday 11/24) 1.sin (70 o ) 2.2tan (x) = cos (x) – 4 = sin (x) + 3 = Solve for the missing side:

Warm-Ups (Tuesday 11/25) 1)A rectangle is 7 cm wide and 10 cm long. Find the length of a diagonal of the rectangle. 2) A 20-foot ladder is leaned against a wall. If the base of the ladder is 8 feet from the wall, how high up on the wall will the ladder reach?

Warm-Ups (Monday 12/1) Solve for the missing side or angle: 1) 2)

Tuesday (12/2/2014) An airplane is flying at a height of 2 miles above the ground. The distance along the ground from the airplane to the airport is 5 miles. What is the angle of depression from the airplane to the airport?

Warm-Ups (Wednesday 12/3) A bird sits on top of a lamppost. The angle of depression from the bird to the feet of an observer standing away from the lamppost is 35 degrees. The distance from the bird to the observer is 25 meters. How tall is the lamppost?

Warm-Ups (Thursday 12/4)

Warm-Ups (Friday 12/5) 1.Triangle ABC has <C = 45, a = 15, and b = 20, what is the area of triangle ABC? 2.Find the original height of the tree if the angle the tree makes with the ground is 25⁰: 15 ft

Warm Ups (Monday 12/8) 1) y = 1 + 1/2sinx a)Amplitude: b)Midline: c)Increasing: d) Decreasing: 2) Look at the diagram below. What is the length of WX? 45

Warm-Ups (Wednesday 12/10) 1)In triangle ABC, m<C = 30 and a = 16. If the area of the triangle is 24, what is the length of side b? 2) In triangle KHS, k = 9, h = 7 and m<S = 130 degrees. What is the area of the triangle rounded to the nearest tenth?
