A basketball with a radius of 24.1 cm rolls 8.0m in 11 seconds. what is the angular frequency of the ball?
Dominik [7]
The formula for angular frequency is:

ω = velocity/radius

Since we are given distance(8.0m) and time(11 seconds) , we can also express the formula as:

ω = distance/(radius)(time)

Substituting the given values:

8.0m/(0.241m)(11s)

Which would give us the answer of 3.03 seconds.

Hope this answer helps.

PLEASE HELP (20pts, attachment below) Find x and y.
kherson [118]

Step-by-step explanation:

5x +2 = 182 -4x

5x+4x = 182-2

9x = 180

x = 180/9

x = 20

4y +2 = 5x +2

4y = 5x

4y = 5(20)

4y = 100

y = 100/4

y = 25

What are the solutions to this problem? (use the quadratic formula and i)<br><br> -2x^2+5x-11=0
Sever21 [200]

Step-by-step explanation:

The quadratic formula is:

x = \frac{-b \pm\sqrt{b^2-4ac} }{2a}\\

A, in this case, is -2.

B is 5

C is -11

x = \frac{-5 \pm\sqrt{5^2-4(-2)(-11)} }{2(-2)}

x = \frac{-5\pm\sqrt{25 -88} }{-4}\\

x = \frac{-5\pm\sqrt{-63}}{-4}

x = \frac{-5+i\sqrt{63} }{-4} and \frac{-5-i\sqrt{63} }{-4}

We can break up the fraction to make it easier on our eyes

x = \frac{5}{4}\pm\frac{i\sqrt{63} }{4}

\frac{\sqrt{63} }{4} ≈1.9843

x = 1.25 + 1.9843i\\1.25 - 1.9843i
