<span>It could be C. If the blade spends twice in a minute, it would be 30 seconds. 30=2pi/B=pi/15. </span>
Answer:
The equation for b would be y = 1/2x + 1
Step-by-step explanation:
In order to find this, start by finding two points on the line. We'll use (0,1) and (2, 2). From there we start by finding the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (2 - 1)/(2 - 0)
m = 1/2
Now using that, we can plug it, along with a point into point-slope form to get the answer.
y - y1 = m(x - x1)
y - 1 = 1/2(x - 0)
y - 1 = 1/2x
y = 1/2x + 1
Answer:

Step-by-step explanation:
{x -4y = −21
{8y - x = 45

The angular speed of the wheel is calculated as 52.36 radians per second
<h3>How to solve for the angular speed</h3>
The revolution of this wheel is said to be at 500 in a minute
This is also called the frequency of this wheel.
This can be written as
500rev in 60 seconds. 500/60 = 8.333 per second
Angular speed is given as
pi = 22/7
f = 8.333
Formular for angular speed = ω = 2*pi*f
w = 2 * 22/7 * 8.333
= 52.36 radians per second
