Find the equation of the ellipse with the following properties.
zalisa [80]
Equation of an ellipse:

(x-h)²/a² + (y-k)²/b² = 1
Since it passes through the origin (0,0) , then h = k = 0 hence the equation:
(x-0)²/a² + (y-0)²/b² = 1
x²/a² + y²/b² = 1

2a = major axis = 2.|5| + |-5| = 10. then a = 5 and a² = 25
2b = minor axis = 2.|3| + |-3| = 6. then b = 3 and b² = 9

Then the final equation is:
x²/25 + y²/9 = 1

a point on the rim of a wheel moves with a velocity of 80 feet per second. What is the angular velocity of the point if the diam
valentina_108 [34]

The angular velocity is 16 radians per second

<u>Solution:</u>

The angular velocity of point is given by formula:

w = \frac{v}{r}

Where,

w is the angular velocity in radians

v is the linear velocity

r is the radius

Given that diameter of wheel is 10 feet

radius=\frac{diameter}{2}

radius = \frac{10}{2}=5

Thus radius is 5 feet

A point on the rim of a wheel moves with a velocity of 80 feet per second

Linear velocity = v = 80 feet per second

Therefore, angular velocity is given as:

w = \frac{80}{5} = 16

Thus angular velocity is 16 radians per second
