6) A right triangle is a triangle with one angle measuring 90°. In a right triangle, the sides are related by Pythagorean Theorem, c^2=a^2+b^2 , where c is the hypotenuse (the side opposite the 90° angle). Find the hypotenuse when the other 2 sides' measurements are 6 feet and 8 feet. 7) Suppose you travel north for 65 k

#120 Digging up the street. A contractor wants to install a pipeline connecting point A with point C on opposite sides of a road. To save money, the contractor has decided to lay the pipe to point B and then under the road to point C. Find the measure of the angle marked x in the figure for exercise #120 on page 161.

Which one of the following trigonometric functions of x is not correct? Which one of the following trigonometric functions of x is not correct given that sin x > 0 and sec x = -2? ? csc x = ( 2 sq rt 3) / 3 ? cos x = - 1 / 2 ? cot x = - ( sq rt 3 ) / 3 ? tan x = - ( sq rt 3 ) / 2

Match sec4 y - tan4 y to one of the following: ? csc y ? sec2 y+ tan2 y ? 1+ tan y ? csc y x cot y

Costs can be classified into two categories, fixed and variable costs. These costs behave differently based on the level of sales volumes. Suppose we are running a restaurant and have identified certain costs along with the number of annual units sold of 1000. Item: Raw Materials (cost for hamburgers) Total Annual Cost: 650

1. If sin(alpha)=1/5 where alpha is in quadrant II, find the remaining five trigonometric functions of alpha. 2. Given that sin(alpha)= -2/3 and cos(alpha)= -root5/3>0, find the remaining four trigonometric functions. 3. Sketch a graph of y=3cos(2theta+pi) using either transformations or the "5 key points" method. Be

Consider the graph of y = tan x. (a) How does it show that the tangent of 90 degrees is undefined? (b) What are other undefined x values? (c) What is

Complete the Identity: 1. cos 4(theta) 2. sin(theta) sin(theta) ---------- - ---------- 1+sin(theta) 1-sin(theta) Use the given information to find the exact value of the expression. 3. Find sin(2theta). tan(theta) = 24/7, theta lies in quadrant III.

1. A surveyor is measuring the distance across a small lake. He has set up his transit on one side of the lake 130 feet from a piling that is directly across from a pier on the other side of the lake. From his transit, the angle between the piling and the pier is 55(degrees). What is the distance between the piling and the p

LOOKOUT STATION A is 15 km west of station B. THE BEARING FROM A TO A FIRE DIRECTLY SOUTH OF B IS 37 DEGREES AND 50'E. HOW FAR IS THE FIRE FROM B?

1. A boat sails at a constant speed in a straight line. its position at time S is (30S- 300,10S +500). in the water there are two buoys, A and B. at positions A- (7100,2800) and B - (125700,42500). a) write an expression in terms of S that is the square of the distance between the boat and buoy A at time S, simplify the answe

Use trigonometric identities to derive the following identities: a.) sin^2x+cos^2x=1 b.) sin2x=2sinxcosx c.) cos2x=cos^2x-sin^2x d.) cos2x=2cos^2x-1 e.) cos2x=1-2sin^2x

I am having difficulty using the epsilon/delta definition....even difficulty when not using it. There's a problem which reads as follows: find the limit as x approaches 0 of (cosx-1)/x^2. The main reason as to why I am having difficulty without using the epsilon/delta definition is because I simply am confused what to do when
