Chapter 8: Q. 53 (page 517)

Suppose that you are headed toward a plateau 50 meters high. If the angle of elevation to the top of the plateau is 20°, how far are you from the base of the plateau?

Short Answer

Expert verified

So the distance is 137.3739 feet.

Step by step solution

01

Given Information

Suppose that you are headed toward a plateau 50 meters high. If the angle of elevation to the top of the plateau is 20°.

02

Solution

We can draw a figure as: -

In △ABCwe have to find BC.

tan(C)=ABBC

tan(c)×BC=ABtan(20°)×BC=50BC=50tan(20°)BC=500.3639BC≈137.3739

03

Final Answer

The distance is 137.3739 feet.

The amplitude A and period T off(x)=5sin(4x) are ____ and ____ .

The displacement d (in meters) of an object at time t (in seconds) is given as d=5sin(3t)

(a) Describe the motion of the object.

(b) What is the maximum displacement from its resting position?

(c) What is the time required for one oscillation?

(d) What is the frequency?

an object of mass m (in grams) attached to a coiled spring with damping factor b (in grams per second) is pulled down a distance a (in centimeters) from its rest position and then released. Assume that the positive direction of the motion is up and the period is T (in seconds) under simple harmonic motion.

(a) Develop a model that relates the distance d of the object from its rest position after t seconds.

(b) Graph the equation found in part (a) for 5 oscillations using a graphing utility.
