ASK YOUR TEACHER The length of each of the two equal sides of an isosceles triangle is 26 meters (see figure). The angle between the two sides is 0. PRACTICE ANOTHER Ꮎ 26 m/ 26 m (a) Write the area of the triangle (in m2) as a function of = 2 A(을)= 0 -338 sin × m² 2 (b) Write the area of the triangle (in m2) as a function of 0. A(0) = = 338 sin 0 ✓ m² Determine the value of such that the area is a maximum. 元 0 = 2 You're right! Need Help? Read It 3 8

An observer views the space shuttle from a distance of x = 6 mi from the launch pad. x mi (a) Express the height of the space shuttle as a function of the angle of elevation 0. h = mi (b) Express the angle of elevation as a function of the height h of the space shuttle. 0 =

You wants to do ride the Ferris wheel. The Ferris wheel has a radius of 9.5 m and rotates once full rotation every 10s. The bottom of the wheel is 1.2 m above the ground.a) Write a cosine equation that gives a rider’s height above the ground, in meters, as a function of time, in seconds, with the rider starting at the bottom of the wheel b) How would the equation written in (a) change if the radius of the wheel was 8 m? List the change(s) and specify the new value(s). c) After 6s, what is the height of the rider?  d) Write a sine equation that models this scenario.

What is the equation of the reciprocal function ?

An observer views the space shuttle from a distance of x = 3 mi from the launch pad. x mi (a) Express the height of the space shuttle as a function of the angle of elevation 0. mi (b) Express the angle of elevation 0 as a function of the height h of the space shuttle.

Which trig function has the same ratio as Sin X?

Suppose you are standing at a distance, d, of 175 feet from a statue of height h feet. h h = d Ө (a) Express the height of the statue as a function of the angle 0. (b) Express the angle as a function of the height of the statue. 0 =
