Chapter 6: Q. 4 (page 364)

A __________ __________ is a positive angle whose vertex is at the center of a circle.

Short Answer

Expert verified

The solution is central angle .

Step by step solution

01

Step 1. Given information 

A positive angle whose vertex is at the center of a circle

02

Step 2. Calculation 

A central angle is a positive angle whose vertex is at the center of a circle. The rays of a central angle subtend (intersect) an arc on the circle. If the radius of the circle isrand the length of the arc subtended by the central angle is alsor, then the measure of the angle is one radian.

Angular Speed of a Race Car A race car is driven around a circular track at a constant speed of 180 miles per hour. If the diameter of the track is 12 mile, what is the angular speed of the car? Express your answer in revolutions per hour (which is equivalent to laps per hour).

A neighborhood carnival has a Ferris wheel whose radius is 30 feet. You measure the time it takes for one revolution to be 70 seconds. What is the linear speed (in feet per second) of this Ferris wheel? What is the angular speed in radians per second?

Hurricanes are categorized using the Saffir- Simpson Hurricane Scale, with winds 111-130miles per hour (mph) corresponding to a category 3 hurricane, winds 131-155mph corresponding to a category 4 hurricane, and winds in excess of 155 mph corresponding to a category
5hurricane. The following data represent the number of major hurricanes in the Atlantic Basin (category 3,4or 5) each decade from 1921to2010.

(a) Draw a scatter diagram of the data for one period.

(b) Find a sinusoidal function of the form y=Asin(蝇x-蠒)+Bthat models the data.
