Chapter 2: Q. 10 (page 119)

A circle of radius ris in inscribed in a square. See the figure.

Part (a): Express the area A of the square as a function of the radius rof the circle.

Part (b): Express the perimeter p of the square as a function of the radius rof the circle.

Short Answer

Expert verified

Part (a): Area of the square as a function is Ax=4r2.

Part (a): Perimeter of the square as a function is px=8r.

Step by step solution

01

Part (a) Step 1. Given information.

Consider the given question,

Side of squarea=2r.

We know the area of the square is A=a2.

Substitute the values,

Ax=2r2Ax=4r2

02

Part (b) Step 1. Given information.

Consider the given question,

Side of squarea=2r

We know the perimeter of the square is role="math" localid="1645809518903" p=4a.

Substitute the values,

px=42rpx=8r

Temperature Measurements The relationship between the Celsius (掳C)and Fahrenheit (掳F)scales for measuring temperature is given by the equation.

F=95C+32

The relationship between the Celsius 掳Cand Kelvin Kscales is K=C+273. Graph the equation F=95C+32using degrees Fahrenheit on the y-axis and degrees Celsius on the x-axis. Use the techniques introduced in this section to obtain the graph showing the relationship between Kelvin and Fahrenheit temperatures.

Cost of Trans-Atlantic Travel A Boeing 747 crosses the Atlantic Ocean (3000 miles) with an airspeed of 500 miles per hour. The cost C (in dollars) per passenger is given by

C(x)=100+x10+36,000x

where x is the ground speed (airspeed卤wind).

(a) What is the cost per passenger for quiescent (no wind) conditions?

(b) What is the cost per passenger with a head wind of 50 miles per hour?

(c) What is the cost per passenger with a tail wind of 100 miles per hour?

(d) What is the cost per passenger with a head wind of 100 miles per hour?

Two cars leave an intersection at the same time. One is headed south at a constant speed of 30 miles per hour, and the other is headed west at a constant speed of40 miles per hour (see the figure). Build a model that expresses the distance between the cars as a function of the time t.

[Hint: At t=0, the cars leave the intersection.]
