A bicycle wheel has a radius of 13 inches.

What is the distance the bicycle will travel after 30 revolutions of the wheel?

Use 3.14 for π .

Step-by-step explanation:

the circumference of a wheel is one revolution

so

formula: circumference=π*diameter

D=26cm (13*2 to find the whole length from one end to other)

so you'll do 3.14*26 equals 81.64

one revolution=81.64

30 revolutions=2,448.3 inches (times by 30 with 81.64)

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
